Abstract:
Sustainability is a widely acknowledged concept in modern day construction scenario. Although the construction industry is transforming in a substantial way in terms of the material used and the equipment used, the construction cost has risen steeply along with the worse impact on the environment due to this it has resulted in the acceptance of method like the use of natural fiber for example Coconut fibre for improving the strength of concrete. Coconut fiber is easily and widely available in abundance, which makes it fairly sustainable as form of reinforcement material in concrete. The use of coconut fibre as in form of reinforcement has also emerged as new source of income for the coconut producer. In addition, it can also be seen as a new effective way for the discarding of coir mattress wastage. The major problem of coconut fibre i.e. high water absorption rate of the fibre can be reduced to certain extent by coating the fibres with appropriate oil. In addition to this, the fibres which are naturally occurring is also ecologically sustainable and can lower the global carbon track effectively. This study aims to analyse the difference in strength of coconut fibre (processed fibres coated with oil and oil raw fibres coated with oil) reinforced concrete at various fibre contents and to collate it with the traditional concrete. The different strength aspects which are analysed in this study are the tensile, compressive and flexural strength of the concrete reinforced with coconut fibre at different percentages like 4%, 5% & 6% by the weight of cement of fibre. The optimum percentage of the raw fibre meshes and processed fibre were found and the optimum percentage of super-plasticizer required for the desired workability was also examined.

Abstract:
Polymeric materials reinforced with synthetic fibres such as glass provide advantage of high stiffness and high strength to weight ratio. Despite these advantages, the widespread use of synthetic fibre-reinforced polymer composite has a tendency to decline because of their high-initial cost and most importantly their adverse environmental impact. In this work, four different composites are prepared with untreated coconut fibres, NaOH mercerized coconut fibres, KOH mercerized coconut fibres and CSM glass fibres. A lot of studies are done earlier on NaOH mercerized coconut fibre composites. But, no studies are done specifically for KOH mercerized coconut fibre composites. So, KOH mercerized coconut fibre composites are prepared in this study. General purpose polyester resin is used for preparing all the compsites. The mechanical properties of composites are studied using the flexural test, impact test and tensile test. The mechanical properties of KOH mercerized coconut fibre composites are studied and compared with the mechanical properties of NaOH mercerized coconut fibre composites, untreated coconut fibre composites and CSM glass fibre composites.

Abstract:
Fire outbreaks in buildings have been a major concern in the world today. The integrity of concrete is usually questioned due to the fact that after these fire outbreaks the strength of the concrete is reduced considerably. Various methods have been adopted to improve the fire resistance property of concrete. This study focused on the use of coconut fibre to achieve this feat. In this study, varying percentages of treated and untreated coconut fibres were incorporated into concrete and the compressive strength was tested for both before heating and after heating. The percentages of replacement were 0.25, 0.5, 0.75 and 1% fibre content by weight of cement. Concrete cubes that had 0% fibre served as control specimens. After subjecting these concrete cubes to 250 °C and 150 °C for a period of 2 h, the compressive strength increased when compared to the control. The compressive strength increased up to 0.5% replacement by 3.88%. Beyond 0.5% fibre, the compressive strength reduced. Concrete having coconut fibre that had been treated with water also exhibited the highest compressive strength of 28.71 N/mm². It is concluded that coconut fibres are a great material in improving the strength of concrete, even after it was exposed to a certain degree of elevated temperature.

Abstract:
The aim of this study is to investigate the effect of polypropylene fibre addition into eco-concrete made with fly ash, an industrial by product, as partial cement replacement material, and coconut shell, an agricultural waste, as coarse aggregates, on the mechanical properties of the concrete. Two different mixes were developed, one with coconut shell only as coarse aggregates, and the other with the combination of both conventional aggregates and coconut shell as coarse aggregates. The cement content was replaced with class F fly ash at 10% by weight in the concrete mixes. The volume fractions of polypropylene fibres used in this study were 0.25%, 0.5%, 0.75% and 1.0%. The addition of polypropylene fibres slightly reduces the slump and density of coconut shell concrete. As the volume fraction of fibres increases, the compressive strength and modulus of elasticity of coconut shell concrete also increases by up to 0.5% of fibre volume fraction. The split tensile strength and flexural strength of coconut shell concrete were also enhanced with fibre addition. The addition of 0.75% and 1.0% volume fractions of polypropylene fibres slightly reduces compressive strength. Results of this study show that polypropylene fibres may be used in coconut shell concrete to improve the mechanical properties of the composite.

Abstract:
In the last few years, there is emerging attention in using Lightweight Foamed Concrete (LFC) as a lightweight non-structural and semi-structural element in buildings to take advantage of its excellent insulation properties. Though, LFC has been noticed to have some disadvantages: considerable brittleness; results in low compressive and flexural strength, poor fracture toughness, poor resistance to crack propagation and low impact strength. Coconut fibre obtained from coconut husk, belonging to the family of palm fibres, is agricultural waste products obtained in the processing of coconut oil. In Malaysia, they are available in large quantities. Coconut fibre is extracted from the outer shell of a coconut. There are many general advantages of coconut fibres e.g. they are moth-proof, resistant to fungi and rot, provide excellent insulation against temperature and sound, not easily combustible, flame-retardant, unaffected by moisture and dampness, tough and durable, resilient, springs back to shape even after constant use, totally static free and easy to clean. Hence this study is intended to look into the potential of coconut fiber in enhancing the engineering properties of LFC. There are 5 engineering properties will be focused in this study which are flexural strength, splitting tensile strength, compressive strength, Poisson’s ratio and Poisson’s ratio toughness. Three densities of LFC of 800 kg/m3, 1100 kg/m3 and 1400 kg/m3 were cast and tested. The ratio of cement, sand and water used in this study was 1:1.5:0.49. Coconut fibers were used as additives at 0.12%, 0.24%, 0.36%, 0.48% and 0.60% by volume of the total mix. Test results indicated that the engineering properties of LFC strengthen with coconut fiber had increased soundly. Coconut fiber inclusion changes the post-peak response at the load-deflection curves for the samples, which modifies the failure mode and enhance the flexural strength, compressive strength and splitting tensile strength.

Abstract:
Currently, the use of composites to replace parts made only with plastics has been gradually employed. The advantages of these composites are low cost, high availability of raw materials and good physical and mechanical properties. Thus, this work aimed at producing and characterizing composites produced with coconut fibre reinforced polyurethane matrices. The coconut fibres were studied as to their chemical constituents, aspect ratio, bulk density, pH, tensile properties, and surface SEM images. The composites were prepared using the hand lay-up process and four different concentrations of coconut fibre were evaluated: 30, 40, 50, and 60%. The composites were assessed as for water absorption after 20 days of immersion, bulk density, impact IZOD, tensile tests, and visualize the matrix-reinforcement interface using SEM. The electron micrographs showed a great deal of impurities on the surface of coconut fibres, such as greases, waxes, and gums, due to the high amount of extraction material (19.78%), which damages the adherence of the polymer onto the coconut fibre and, as observed, cause detachment between the reinforcement and the matrix. The tensile strength of the composites tended to increase as greater amounts of coconut fibres were added to the matrix. The averages were around 6.51 to 6.72 MPa for composites with 30 and 60% fibres, respectively. Therefore, coconut fibres can be considered as an alternative to synthetic fibres commonly used in composites, and they can be used at a ratio of 60% without prejudicing the properties of the composites, making them lighter and cheaper.

Abstract:
Natural fibres are considered as a potential replacement for man-made fibers in composite materials because of their advantages over other established materials. However, serious problem of natural fibres is their strong polar character which creates incompatibility with most polymer matrices. In present investigation, the effect of alkaline, silane and combination of both treatments is investigated. Tensile properties and fracture toughness of coconut spathe fibre for untreated and treated were evaluated. Samples were fabricated by using the hand layup process. Result indicated that silane treatment has achieved a better performance for the tensile test while there is none improvement fracture toughness was displayed by silane or alkaline treatment as compared to untreated fibres. The alkaline treatment showed to be harmful for fracture toughness of the coconut spathe fibre since the improved interfacial adhesion impaired the main energy absorption mechanisms.

Abstract:
The rate of global deforestation and its impact on the environment has led particle board manufacture to search for alternative feedstock, especially in countries where wood is less available compared to other cellulosic natural product. Based on the properties of coconut fibre and PET bottle, these two materials can be recycle as raw material for manufacture of panel board. As for this study, the coconut fibre were used as the filler and PET bottle as outer lining of the panel board. Two types of coconut fibre were used which are grinding and un-grinding coconut fibre. At first, the coconut fibre are undergoes softening, grinding, drying and sieving process, while PET bottle was cleaning, shredding, sieving before compacted using hydraulic hot press machine. There are four types of testing that been carried out which are swelling, water absorption, Modulus of Elasticity (MOE) and Modulus of Rupture (MOR). The result show the conventional board has the highest value for MOE test, so it’s indicate that the conventional board is less strength from the coconut fibre board. As for water absorption test, the average water absorption of coconut fibre based panel board is less than conventional board. Overall, the coconut fibre board is better than conventional panel board because coconut fibre board are less swelling, has low water absorption, high modulus of rupture and low modulus of elasticity. Based on the finding, this coconut fibre panel board has potential as a stronger and long-lasting panel board than the conventional board in the market. Other than that, the panel also have their own aesthetic value since the recycled plastic bottle used as outer lining is colourful and giving aesthetic value.

O presente trabalho tem por objetivo oferecer subsídios para análise do ciclo de vida de assentos a base de fibra de coco com látex. Com esse intuito foi realizado um estágio junto a uma Unidade de beneficiamento e industrialização da fibra de coco, localizada na comunidade de Praia Grande, no município de Ponta de Pedras, Ilha do Marajó, no Estado do Pará. Nesse estágio foram coletados dados a respeito de todo o processo de beneficiamento da fibra de coco até a produção de mantas a base de fibra de coco com látex para aplicação em veículos. Através da Mercedes-Benz do Brasil, foram feitas amostragens dos materiais em estudo: fibra de coco, manta de fibra de coco com látex e espuma de poliuretano. É importante notar que a fibra de coco e suas mantas foram fornecidas pela Unidade de beneficiamento e industrialização de fibra de coco já citada e, a espuma de poliuretano foi fornecida pela Empresa Sanko de Diadema - SP. A partir dessas amostragens foram realizados ensaios de compressão e torção, apenas compressão, análise de metais e análise qualitativa do produtos formados na pirólise desses materiais, visando analisar assentos automobilísticos a base de fibra de coco com látex como um possível substituto da espuma de poliuretano. A partir deste estudo foi possível verificar que ambos os materiais sofrem deformação volumétrica após os ensaios de compressão e torção e, apresentam um comportamento de retorno ao seu volume inicial. No entanto, a espuma retorna praticamente 100% ao seu volume inicial enquanto a manta de fibra de coco com látex mantém uma deformação em torno de 10%. Quanto a análise qualitativa dos produtos formados na pirólise a 800oC desses materiais verificou-se que o fumo produzido pela pirólise da espuma de poliuretano é mais tóxico em relação ao produzido pela manta de fibra de coco com látex.

Part of the work was developed at a unit for manufacture and industrialization of coconut fibres, at the community of Praia Grande, town of Ponta de Pedras, Marajó Isle, Pará, Brazil. At the unit, information on the processing of the coconut fibre was collected, ranging from the raw material to the production of a mat of natural fibre with latex to be used in vehicles. The different materials involved in the study were analysed at the laboratories of Mercedes-Benz do Brazil: coconut fibre, the mat of natural fibre with latex, and polyurethane foam. The polyurethane foam was supplied by Sanko, from Diadema/SP. Once obtained the samples, they were submitted to tests of compression and torsion, compression only, analysis of heavy metals content, and qualitative analysis of products resulting from the incineration of the different materials. The coconut fibre plus latex composite was evaluated as a possible substitute for polyurethane foam in seats. Starting from this study it was possible to verify that both materials suffer volumetric deformation after the compression rehearsals and torsion and, they present a return behaviour to its initial volume. However, the foam comes back 100% practically to its initial volume while the mat of coconut fibre with latex maintains a deformation around 10%. As the qualitative analysis of the products formed in the pyrolysis to 800oC of those materials was verified that the fume produced by the pyrolysis of the polyurethane foam is more toxicant in relation to the produced by the mat of coconut fibre with latex.

L’objectif de ce travail est de caractériser le comportement mécanique de composites constitués à de matrices polymériques renforcées par des fibres naturelles. Les matériaux étudiés dans cette thèse sont le polypropylène pour la matrice et les fibres de coco pour les renforts. La caractérisation morphologique et mécanique de ces matériaux est entreprise grâce à l’usage de la microscopie électronique à balayage, la tomographie aux rayons X, la corrélation d’images numériques et la thermographie infrarouge. Dans une première partie, on a étudié en détail les fibres de coco dans trois états différents: à l’état naturel et après traitement chimique suivi ou non de séchage. Les fibres ont été observées en tomographie et leurs caractéristiques essentielles définies. Par ailleurs des essais mécaniques in-situ dans un microscope électronique à balayage ont été conduits pour l’obtention de leurs propriétés mécaniques. Il a quasi été procédé à la caractérisation mécanique du comportement de tissus de fibre en vue de leur utilisation dans un composite. Dans une seconde partie, le comportement mécanique du polypropylène (à l’état vierge ou recyclé) a été analysé grâce à des essais de traction à déplacement imposé et à diverses vitesses de chargement. Ces essais ont été instrumentés pour des mesures de champs de déplacement et de températures, les premiers servant à mesurer les états de déformation, la progression de l’endommagement et observer les modes de rupture du matériau. L’effet du recyclage est souligné et en particulier la dégradation des propriétés mécaniques. Les caractéristiques complètes (élasticité, pic et plateau et endommagement) et l’effet de la vitesse sur celles-ci sont exhibées pour les deux états. Dans la dernière partie du travail, on s’est intéressé au comportement du composite considérant la matrice à l’état vierge ou dans l’état recyclé. Les caractéristiques obtenues sont discutées en soulignant l’influence du mode d’élaboration utilisé et l’apport des fibres de coco
The objective of this work is to characterize the mechanical behavior of composites made with recycled polymeric matrices reinforced with natural fibers. The materials studied in this thesis are the polypropylene matrix and the coconut fibers for reinforcement. The morphological and mechanical characterization of these materials is undertaken with the use of scanning electron microscopy, X-ray tomography, the digital image correlation and infrared thermography.In the first part, we studied in detail the coconut fibers in three different states: in its natural state and after chemical treatment followed or not drying. The fibers were observed in tomography and their essential characteristics defined. Furthermore in situ mechanical testing in a scanning electron microscope were conducted to obtain their mechanical properties. It has almost been carried out the mechanical characterization fabrics of the behavior for use in a composite. In a second part, the mechanical behavior of polypropylene (virgin or recycled state) was analyzed by tensile testing at imposed displacement and various charging speeds. These tests were instrumented for measurement of displacement fields and temperatures, the first to measure the deformation conditions, the progression of the damage and observe the failure modes of the material. The effect of recycling is particularly pointed out and degradation of mechanical properties. Complete specifications (elasticity, peak and shelf and damage) and the effect of speed on them are exhibited for both states. In the last part of the work, it was interested in the behavior of the composite matrix considering the blank state or in the recycled state. The characteristics obtained are discussed emphasizing the influence of the method of production used and the contribution of coconut fibers

Two batch mesocosms were created on site in Da Nang, Vietnam to reduce nutrients in wastewater from fish processing factories. The mesocosms contained either activated carbon or coconut fibre which in earlier studies has shown promising results in wastewater treatment. Three aspects of the materials were compared; Chemical content, which measured levels of COD, total-nitrogen and total-phosphorus. Rate of biofilm formation, where biofilm were measured visually and through weight. The last aspect was microbiological presence where fours species of microorganisms were cultivated. The experiment showed no obvious difference between the materials but concludes that this is an experiment that could and should be developed further.

Abstract:
Au Burkina Faso, l'un des soucis majeurs demeure la gestion des eaux usées et excréta. Dans l'optique de trouver une alternative à l'assainissement autonome (assainissement non collectif), des technologies biologiques rustiques par cultures fixées sur supports fins, destinées aux petites et moyennes collectivités ont été expérimentées. Le premier volet du travail expérimental à consister à évaluer les performances comparées du sable et des fibres de coco en traitement d'eaux résiduaires urbaines après un processus anaérobie par lagunage. Dans une deuxième étape, ont été évaluées les performances épuratoires de filtres plantés de Andropogon gayanus Kunth et Chrysopogon nigritana (Benth) Veldkamp deux poaceae des zones tropicales. Les abattements moyens d'élimination de la pollution biodégradable sont respectivement de 99% et 98% à la sortie du filtre à sable et de celui de substrat de coco. Cependant, il y a une DCO ajoutée due à l'extraction de composés phénoliques du substrat de coco qui occulte les performances réelles de ce support de culture. Toutefois, en l'absence d'une bonne nitrification au sein du massif de substrat de coco, contrairement au sable, nous avons relevé une élimination de l'azote sous forme d'ammonium avec un rendement de 75%. Par ailleurs, ce matériau végétal par sa structure très poreuse a montré une plus grande capacité à éliminer les sels minéraux comparativement au sable. Quant aux filtres plantés de Andropogon gayanus et Chrysopogon nigritana, si les deux pilotes ont assuré des abattements de plus de 97% de la DBO5, le premier a assuré un prélèvement plus important des nutriments (N et P).

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIRO
Este estudo apresenta o comportamento de um solo argiloso reforçado e não reforçado com fibras de coco verde (resíduo proveniente do consumo da água de coco), através da realização de ensaios de caracterização e ensaios mecânicos de compactação e de ensaios triaxiais isotropicamente drenados. A fibra de coco utilizada foi obtida por processo mecânico na empresa ECOFIBRA, que possui uma parceria com a Companhia de Limpeza Urbana da cidade do Rio de Janeiro (COMLURB) em projeto piloto de coleta seletiva das cascas de coco verde. O material recebido foi estudado de duas maneiras, as fibras foram inseridas ao solo moídas e cortadas (no comprimento aproximado de 2cm). O solo argiloso, de origem coluvionar, foi retirado do campo experimental da PUC-Rio. Busca-se estabelecer padrões de comportamento que possam explicar a influência da adição da fibra de coco verde, relacionando-a com os parâmetros de resistência ao cisalhamento do solo e dos compósitos. Os ensaios foram realizados em amostras compactadas na densidade máxima e umidade ótima, com teores de fibra moída de 0,5 por cento e 1 por cento e teores de fibra cortada de 0,5 por cento, 0,75 por cento, 1 por cento, 1,25 por cento e 1,5 por cento, em relação ao peso seco do solo. Observa-se um incremento na resistência ao cisalhamento das misturas solo-fibra, uma vez que se observa um discreto aumento do ângulo de atrito e em um expressivo aumento da coesão das misturas reforçadas, em comparação aos dados obtidos para o solo puro. Os resultados se mostraram satisfatórios para aplicação do solo reforçado com fibras de coco em camadas de aterros temporários submetidos a carregamentos estáticos, dando assim uma destinação mais sustentável a este resíduo, atendendo às questões ambientais e sócio-econômicas.
This study presents the behavior of reinforced and unreinforced clay soil with green coconut fibers (waste from consumption of coconut water), by conducting tests for the characterization and mechanical compaction tests and isotropically drained triaxial tests. The coconut fiber used is obtained by a mechanical process in ECOFIBRA company, which has a partnership with the Urban Cleaning Company of the city of Rio de Janeiro (COMLURB) in a pilot project about separate collection of green coconut shells. The received material was studied in two ways; the fibers were inserted into the milled and cut (in the approximate length of 2 cm). The clay soil, with colluvium origin, was removed from the experimental field of PUC-Rio. Seeks to establish patterns of behavior that might explain the influence of the addition of green coconut fiber, relating it to the parameters of shear strength and deformation of soil and composites. The tests were performed on samples compressed at maximum density and optimum moisture content in the milled fiber of 0.5 percent and 1percent fiber content and the cut of 0.5 per cent, 0.75 per cent, 1 per cent, 1.25 per cent and 1.5 per cent on dry weight of the soil. Observed na increase in shear strength of the soil-fiber mixtures, since it was observed a modest increase in friction angle and a significant increase in the cohesion of reinforced mixtures, ompared to the data obtained for the pure soil. The results ere satisfactory for application of soil einforced with coconut fiber layers temporary landfills subjected to static loads, thus giving a more sustainable destination to this residue, given the environmental and socio-economic.

Com o objetivo de avaliar a curva de crescimento, acúmulo de nutrientes e modificações químicas do substrato para a cultura do pimentão cultivado em fibra da casca de coco foi instalado um experimento em casa de vegetação, o qual constou inicialmente de 160 plantas (‘Eppo’) divididas em quatro blocos. Foram analisadas duas plantas por bloco a cada 21 dias após o transplante. O cultivo do pimentão foi realizado em vasos plásticos de 13 dm3, contendo fibra da casca de coco, e dispostos em fileiras duplas nos espaçamentos 0,5 m x 0,8 m entre fileiras simples e 1,10 m entre fileiras duplas. Em cada amostragem, foram avaliadas as características relacionadas ao crescimento da planta, bem como a produção e a qualidade de frutos maduros. A massa seca na parte aérea atingiu o máximo de 451,56 g planta-1 aos 189 dias após o transplante (DAT). As produções de matéria seca de folhas, caule, raiz e frutos aumentaram ao longo do tempo atingindo os valores máximos de 68,79; 65,86; 11,58 e 302,91 g planta-1 aos 189 DAT, respectivamente. O mesmo aconteceu com a área foliar por planta, altura da planta e a taxa de crescimento absoluto, cujos valores máximos foram 6.183,51 cm2, 136,99 cm e 4,47 g planta-1 dia-1, respectivamente. Conclui-se que o crescimento da planta foi contínuo ao longo do ciclo sendo que os frutos acumularam a maior quantidade de matéria seca. A produção comercial de frutos maduros estimada foi 97,3 t ha-1, sendo toda a produção classificada como Extra. Foi verificado acúmulo de 8,22 g planta-1 de N, 1,14 g planta-1 de P, 7,84 g planta-1 de K, 3,25 g planta-1 de Ca, 1,34 g planta-1 de Mg, 2,24 g planta-1 de S, 16,65 mg planta-1 de B, 3,36 mg planta-1 de Cu, 45,98 mg planta-1 de Fe, 34,78 g planta-1 de Mn e 22,28 mg planta-1 de Zn.

Resumo: Dentre as fibras vegetais, a fibra de coco (Cocos nucifera L.) é uma das mais utilizadas no desenvolvimento de produtos ecológicos. Apesar da grande disponibilidade, devido ao consumo de água de coco, a fibra do coco verde apresenta menor aplicação do que a proveniente do coco maduro. Em embalagens secundárias e de transporte, as fontes celulósicas provenientes de árvores coníferas, apresentam intensa utilização, contudo, ainda não se constatou a utilização de fibras lignocelulósicas no setor de produtos hortícolas. Neste trabalho, buscou-se investigar o desempenho da fibra de coco verde como material de acolchoamento em sistemas de embalagens para duas frutas tropicais: mamão (Carica papaya L.) e manga (Mangifera Indica L.). A parte experimental consistiu na obtenção da fibra de coco, desenvolvimento de mantas de fibra, avaliação do desempenho mecânico como material de acolchoamento e avaliação quanto à vibração em teste de simulação de transporte. Em todos os experimentos, utilizou-se como comparativo, a palha de madeira proveniente de coníferas (Pinus eliottii). Para o mamão, a fibra de coco foi tão eficiente quanto à palha na prevenção de injúrias na polpa, mas não evitou abrasões na superfície. Observou-se também redução na taxa de respiração, sem interferência na perda de massa e na variação da cor da epiderme. Por outro lado, o sistema de embalagem com a fibra de coco foi mais eficiente para a manga do que para o mamão, pois a fibra protegeu o fruto contra injúrias internas. Tal comportamento contribuiu para os bons resultados de cor e de produção de gás carbônico. Assim, como material de acolchoamento, a fibra de coco verde apresentou desempenho mecânico comparável à classe de materiais celulósicos. Quanto à aplicabilidade, é possível proteger frutos tropicais, utilizando a fibra de coco verde no seu estado natural, sendo que a viabilidade poderá tornar-se mais expressiva com o desenvolvimento de bandejas ou mantas de fibra com aglutinantes naturais, tais como o gel de fécula e o látex de seringueira utilizados neste trabalho
Abstract: Among the vegetable fibers, the coir (Cocos nucifera L.) is one of the most used in the development of environmentally friendly products. Despite the large amounts, due to the consumption of coconut water, green coconut fiber has less application than that of the mature coconut. The cellulosic sources from coniferous trees have extensive use in secondary packaging and transportation; however, one has still not found its use of lignocellulosic fibers in the vegetable sector. In this study, it was sought to investigate the performance of green coconut fiber as a cushioning material in packaging systems from two tropical fruits: papaya (Carica papaya L.) and mango (Mangifera Indica L.). The experimental part consisted of obtaining the coconut fiber, development of webs of fiber and evaluating mechanical of the cushioning material on the vibration test to simulate transport. In all experiments, was used for comparison, the straw of wood from conifers (Pinus eliottii). For papaya, coconut fiber was as efficient as the straw in the prevention of damage in the pulp, but did not prevent abrasions on the surface. It was observed reductions in respiration rate, without interference in the weight loss and the variation in skin color. Moreover, the packaging system with coconut fiber was more efficient than the sleeve for papaya, as the fruit fiber protected against internal injuries. Such behavior has contributed to get good results of color and carbon dioxide production. Thus, as a cushioning material, the green coconut fiber had mechanical performance comparable to the class of cellulosic materials. In relation to applicability, it is possible to protect tropical fruits, using green coconut fiber in their natural state, and its viability may become more significant with the development of fiber mats or trays with natural binders such as starch gel and latex rubber used in this work

Abstract:
O presente trabalho considerou o potencial de utilização de subprodutos da agroindústria como casca de coco verde e bagaço de cana-de-açúcar, com o intuito de agregar valor a esses materiais, por meio da fabricação de chapas de partículas multicamadas (3 camadas: 2 camadas externas - CE e uma camada interna - CI), utilizando resina poliuretana bi-componente à base de óleo de mamona (PU-mamona). As chapas produzidas foram avaliadas por ensaios termo-físico-mecânicos: condutividade térmica, densidade aparente, perfil de densidade, absorção de água, inchamento em espessura, flexão estática, flexão dinâmica, tração perpendicular, arranchamento de parafuso, dureza Janka e abrasão, com objetivo de verificar as características do material e indicá-lo para usos específicos; microestrutural: microscopia eletrônica de varredura visando identificar características microestruturais do compósito para interpretar as propriedades físico-mecânicas do produto; durabilidade: envelhecimento natural para expor o material a condições ambientais externas e envelhecimento acelerado para exposição a condições internas. Os resíduos utilizados, o adesivo PU-mamona e os parâmetros de produção adotados mostraram-se adequados para fabricar chapas de partículas multicamadas de baixa (529 kg/m3) e média (692 kg/m3) densidade. O ensaio de condutividade térmica permitiu classificar as chapas em estudo na categoria de materiais isolantes onde os valores estiveram entre 0,14 e 0,17 W/m.K. Os perfis de densidade obtidos permitiram observar a variação da densidade ao longo da espessura das chapas e indicou diferenças entre as chapas homogêneas e multicamadas. As chapas multicamadas apresentaram melhores propriedades físico-mecânicas, em comparação com as chapas de partículas homogêneas e atenderam os requerimentos estabelecidos pelos documentos normativos nacionais e internacionais. Os resultados de envelhecimento natural e acelerado indicaram que as chapas em estudo (homogêneas e multicamadas) são sensíveis às condições de exposição externas (temperatura, umidade e radiação) e às condições extremas de exposição interna (umidade e radiação UVB).
This study considered the potential use of agro-industrial wastes like green coconut shell and sugarcane bagasse in order to add value to those materials, by mean fabrication of multilayer particleboards (3 layers: 2 external layers - EL and internal layer - IL), using castor oil-based polyurethane adhesive. The particleboards were evaluated using physic-mechanics tests: density, density profile, water absorption, thickness swelling, static flexure, dynamic flexural, perpendicular traction, screw pullout, Janka hardness and abrasion with the objective to verify the material characteristics and to indicate specific uses, microstructural: Scanning electron microscopy looking to identify microstructural characteristics of composite to interpret the physic-mechanics properties of product, durability: natural aging to expose the material to external environmental conditions and accelerated aging for exposure to indoor conditions. The residues used, the castor oil-based polyurethane adhesive and the parameters of production adopted; proved to be suitable for making multilayer particleboard of low (529 kg/m3) and medium (692 kg/m3) density. The thermal conductivity test allowed to classify the plates in the category of insulating materials with values between 0,14 e 0,17 W/m.K. The density profiles obtained made possible to observe the change of density along the thickness of the boards and showed differences between the homogeneous and multilayer sheets. The multilayer boards presented better physical and mechanical properties in comparison with the homogeneous particleboards and complied with the standards national and international. The results obtained after the natural and accelerated aging indicated that the plates being studied (homogeneous and multilayer) are sensitive to external exposure conditions (temperature, humidity and radiation) and to the extreme conditions of internal exposure (moisture and UVB radiation).

Abstract:
Sustainability is a key in modern construction scenario. Even when the construction industry underwent a revolution in terms of equipment and materials used, the resultant impact on environment skyrocketed. This leads to the adoption of more sustainable approaches in construction like using coconut byproducts such as coconut fibre and shell as additives in concrete. Coconut fibre is abundantly available material which makes it a viable reinforcement material in concrete and the same goes for coconut shell which can be used as a partial replacement for conventional aggregate. This can further act as a new source of income for the coconut producers who get the benefit of the new demand generated by the construction industry. It is also an effective method of disposal of coconut husks and shells and thus reduces their negative impact on the environment. This project aims at studying the variation of strength of coconut fibre reinforced concrete (CFRC) with different percentages of coconut fibre (0.5%, 1%,1.5% and 2% by weight of cement), coconut shell aggregate concrete by replacing coarse aggregate with different percentages of coconut shell ( 15%, 30% and 45%) compared with that of conventional concrete. The optimum percentage of both fibres to be added and coconut shell to be used is determined by analyzing the strength aspects such as flexural, compressive and tensile strength. This project also includes the investigation on the mechanical properties of CFRC with coconut shell aggregate by incorporating coconut fibre and shell together in concrete matrix.

Abstract:
In developing future electrical networks, it is crucial to develop new alternatives insulating materials which can improve the performance of the next generation high voltage cables. The high electric field reduces the resistance of solid insulation and causes partial discharge occurs through the impurities in a dielectric where this phenomenon causes ageing to the dielectric and ultimately leads to breakdown. Thus, this paper seeks to analyse the electric field intensity of High Density Polyethylene (HDPE) when added with 10%, 20% and 30% of different types of bio-filler such as coconut coir fibre, pineapple leaves fibre, and oil palm empty fruit bunch. This can be achieved by creating a two-dimensional (2D) axisymmetric electrostatic model by using the Finite Element Method Magnetics (FEMM) 4.2 software. The results showed that the inclusion of bio-filler in HDPE increased the maximum electric field intensity when compared with unfilled HDPE. The electric field intensity also varied with the different percentages loading of biocomposite and their permittivity. As a result, the maximum electric field intensity was much lower for HDPE added with a 10% loading of the oil palm empty fruit bunch. Hence, oil palm empty fruit bunch was the best composition as it tends to improve the dielectric properties since it has a lower electric field intensity at the top sphere electrode as compared to other compositions.
