Abstract:

Synthetic ropes are popular for application in marine boat as docking, anchor, tow, and sailing. The advantages of synthetic ropes are waterproof, strong and durable, can be designed for sinks or floats and able to stretches. Synthetic ropes are stronger, more resistant to rotting than ropes created from natural fibers. Synthetic ropes also possess certain disadvantages of slipperiness, and can be damaged more easily by UV light. Synthetic ropes is recognizes as a source of microplastic fiber pollutant in marine area. In this work a bark of Hibiscus tiliaceus three is introduced as candidate source of natural fiber for rope to reduce number of microplastic fiber pollutant from synthetic rope. The bark was taken from a trunk with diameter around 20 cm. The bark was immersed in water for 7 days and subsequently was soaked in 5% NaOH solution for 2 hours. Fiber obtained then was dried. It was prepared 7 valid single fiber samples. The average of tensile strength of single fiber obtained by using this method is found around 44.604 MPa. The average of Modulus elasticity E is found 365.864 MPa. The failure strain is found 11.6 %.

Abstract:

Carbon fiber is mainly distributed in the shape of short fibers and continuous fiber bundles as the reinforcing phase in metal matrix composites, and it is seldom studied as braided rope shaped to reinforce the matrix. For this paper, the pretreatment and the surface metallization of the carbon fiber braided rope were studied. Besides, the casting experiments of aluminum-based carbon fiber braided rope composites were performed without external pressure. XPS analysis shows that the surface of the carbon fiber braided rope treated with ultrasonic degumming contains many hydrophilic oxygen-containing functional groups C-OH, C=O, COOH, etc., which can effectively improve the wettability between the carbon fiber braided rope and the aluminum matrix. SEM, EDS, and XRD were used to analyze the micromorphology and structure of the copper plating on the surface of carbon fiber braided ropes obtained from different pH plating solutions. When pH is 12, a continuous, uniform, and dense layer was formed on the surface of carbon fiber braided ropes. In addition, copper coating can effectively inhibit the formation of Al4C3 brittle phase. Finally, the mechanical properties results indicated that the tensile strength of the carbon fiber bundle and carbon fiber rope reinforced composite materials were 69 MPa and 83 MPa, respectively, indicating that the reinforcing effect of the carbon fiber rope is better than that of the carbon fiber bundle.

Abstract:

Thermal damage is an important failure mechanism that affects the bending failure of fiber ropes. This is relevant because synthetic fibers often have a relatively low melting point and low thermal conductivity. In cyclic bending over sheave (CBOS), the heat generated by friction and deformation is not conducted rapidly to the external environment, and the temperature of the rope core increases quickly. This higher temperature greatly reduces the mechanical properties of the fiber, thus accelerating the final rope failure. In this paper, evidence of thermal damage in the bending process of a braided synthetic fiber rope is given. The test conditions inducing thermal damage are discussed, including stress level, bending frequency and diameter ratio. The reasons for the heat generation and the dynamic process of heat accumulation inside the rope during CBOS are also discussed. This study aims to provide theoretical and experimental guidance for the design and use of fiber rope.

Abstract:

Ultra-high molecular weight polyethylene fiber (UHMWPE) exhibits outstanding strength to weight balance due to high molecular orientation, high crystallinity and low density. For these reasons, is widely used in applications demanding high strength high modulus fibers. This paper systematically studies the relationships between the mechanical properties of ropes made of ultra-high molecular weight polyethylene fiber and several attributes of the rope construction. By studying the structure of the rope, a formula relating the Young's modulus and twist angle was developed. It was found that the breaking strength and the elongation of the rope were closely related to the twist angle. Finally, the breaking strength of the rope had a positive correlation with the diameter of the rope. The retention rate of fatigue strength studied in this paper was kept above 100%. These results may provide useful guidance to the industrial production of the UHMWPE based ropes.

Abstract:

As soft elements for force transmission, braided fiber ropes play important roles in many fields where the fiber ropes are used bent over sheaves, while the relevant experiments are time-consuming and expensive. Computational simulation is a promising choice for evaluating the performance of fiber ropes when bent over a sheave. This article presents two methods that could be employed to build a model of braided rope bent over a sheave. One is the mathematical method which deduces the exact mathematical equations of braiding curves based on the Frenet–Serret frame. The spatial equations, considering the phase difference of strands in the same direction and the difference of strands’ projection in different directions, are discussed carefully. The final equation of braided strands is confirmed by modeling the braided rope in Maple® 17. The other method, which is inspired by the analysis of braiding movements, is based on the intersection of surfaces of braiding surface and helical surface which are introduced and defined based on the motion analysis of bobbins and take-up roller. The SolidWorks® 2018 is successfully employed to realize the modeling process.

Abstract:

A steel portal frame subjected to an external blast is analyzed. The use of diagonal synthetic fiber ropes to brace the frame is studied. The force-elongation relationship of the ropes when in tension is modeled either as a bilinear function with initial slackness, or a power law based on tests. The effect of the ropes in reducing deflections and plastic strains is determined using the finite element software ABAQUS/Explicit. Inclusion of the influence of strain-rate on the material behavior of the frame is important. Several blast magnitudes and rope stiffness coefficients are considered. Snap loads occur in the ropes if the blast is sufficiently large. Deformations and strains may be reduced significantly by the ropes, and failure may be prevented.

Abstract:

A comparative study of lifting lines for subsea equipment decommissioning was conducted to evaluate the applicability of fiber ropes. Generally, conventional steel wire ropes are used for subsea equipment decommissioning operations, but there are some disadvantages in using steel wires as the lifting lines at deepwater depth. To overcome the disadvantages, fiber ropes are proposed for using as lifting lines. The comparative methods to evaluate the performance of both lifting lines include three sections of calculations, payload capacity, and horizontal offset due to current, critical length of lifting line. Moreover, dynamic analysis using Orcaflex was performed to compare the dynamic forces occurring in the lifting lines during subsea equipment decommissioning. The results showed that the fiber ropes had advantages in payload capacity, critical length of lifting line and lower dynamic forces occurred compared to the steel wire ropes at deepwater depth.

Abstract:

The tensile property of two-dimensional (2-D) braided cored ropes with high-performance is investigated and found that braiding angle has an evident fluence on the tensile characteristic.In the skin-core structure, the core yarns are straight and parallel with each other ,and have a larger percentage than those in other style of cored rope. The tensile strength and breaking elongation of the samples with different braiding angle is tested by Shimadzu universal testing machine. The load-displacement curves of the rope are drawn and analyzed. It shows that of the tensile fracture mechanism is different from the other structural ropes, and the straight state of the core yarns leads to higher utilization of fiber strength. The results also indicate that braiding angle has a great influence on the strength and breaking elongation of cored rope. In the five samples, the sample with 30°has the both ideal tensile strength and ideal elongation. Beyond the angle, the greater braiding angle is, the much more closely the core yarns are wrapped. The greater friction between fibers of core yarn decreased motion of the fiber in core yarn, some of them was fractured before all the yarns were straighten. The utilization of the braiding yarn fiber strength decreased.

Abstract:

Modern synthetic fiber materials coupled with the various rope constructions that are currently available produce a wide variety of ropes well suited for today's fishing applications. Ropemakers provide many products designed exclusively for fishermen. The market is large, which encourages competition; however, it is also very cost sensitive which can inhibit research and development. This article begins with the history of ropemaking and goes on to describe modern ropemaking materials and designs, the properties and applications of rope in fishing, and sources of rope information. Whale entanglement and environmental concerns are areas where the selection, use, control and disposal of rope fishing gear could well become regulatory issues. An ongoing whale entanglement research program may be a model that will stimulate research.

Abstract:

In recent work, a design methodology for multi-lay wire strands has been developed. The current paper expands on this earlier work to study wire ropes in which the strand is a basic component. Wire ropes with the three types of cores, independent-wire-rope-core (IWRC), fiber-core (FC), and wire-strand-core (WSC), are considered. This work further generalizes the previously developed linearized theory which, through substantiation with experiment, is felt to be reasonably accurate for most wire rope behavior. The theory is then utilized to examine various parameters in the design of wire ropes.

Abstract:

Agel ropes have lower mechanical properties (breaking strength and elongation) than synthetic fiber ropes. Chitosan coating is expected to improve the mechanical properties of agel ropes. The aims of this study are to investigate the effect of immersion in chitosan on the physical and mechanical properties of agel ropes, and to examine the breaking strength and elongation of coated agel ropes after being soaked in both freshwater and seawater. This experimental study was conducted at the Laboratory of Fishing Gear Technology, Department of Fisheries Resources Utilization IPB University, and Laboratory of Forest Product Engineering, Department of Forest Products IPB University. The experiment involved 3 mm in diameter of two agel ropes incorporating control rope and agel rope soaked in 1% chitosan for 24 hours. The control rope was light brown, stiff, and rough, while the treated rope was darker, less stiff, and smoother. The breaking strength of control and treated rope was significantly different (P<0.05), which in respect constitute 15.06 kgf and 24.54 kgf. The elongation of both ropes were also significantly different (P<0.05), making 10,56% for control and 18,04% for treated rope. Breaking strength of the agel rope decreased by 50% after being immersed for 28 days. Keywords: agel rope, chitosan, breaking strength, elongation

Abstract:

Until the present days, in discontinuous conveyor systems, e.g. cranes and elevators, steel wire ropes and steel chains are the exclusively used tension members. Nevertheless, these tension members are exhibiting essential disadvantages, e.g. high dead weight, low bending flexure and high susceptibility to corrosion. For fulfilling the steadily increasing requirements especially in running ropes, alternative tension members have to be developed and approved concerning their series-production readiness by utilization of new technologies and new materials. High-strength fiber ropes are demonstrating promising mechanical properties, regarding tensile strength, vibration behavior and bending fatigue life. Still, the application of such high-strength fiber ropes is limited, due to unavailable systematic investigations and insufficient guidelines for dimensioning and processes for determination of discard criteria. With the help of new technologies and procedures, e.g. multi-zone cyclic bend-over-sheave (CBOS) test machinery and computer-assisted tomography, new knowledge concerning the wear behavior of fiber ropes is to be gained and new discard criteria are to be developed.

Abstract:

The tensile mechanical properties of polyethylene/silica (PE/SiO2) composite fiber and three-strand PE/SiO2composite fiber ropes were investigated. It was found that the SiO2content had a significant effect on the tensile mechanical properties of composite fiber. The breaking force of the fishing three-strand PE/SiO2composite fiber rope with diameter 8 mm was 15.8 kN. Compared to common synthetic fiber rope with the same diameter, fishing three-strand PE/SiO2composite fiber rope had higher breaking force and less elongation. On the premise of maintain the breaking force, the common synthetic fiber rope could be replaced by the fishing three-strand PE/SiO2composite fiber rope in fishing area, and the linear density, the elongation at break, the netting gear resistance and using diameter of rope decreased. Therefore, an efficient method to improve the tensile mechanical properties and lower cost by using composite fiber rope was established.

Abstract:

In this review, previous studies about the properties and applications of natural fiber composites in the aerospace and automobile fields will be discussed. Natural fiber composites are a better alternate to the existing artificial fiber composites due to their advantages, e.g. lightweight, cheaper and, most importantly, their environmental aspects and biodegradability. Since ancient times, natural fibers have been used for preparing walls, baskets, ropes, clothes, and many more products. More recently, natural fibers such as jute, kenaf, sisal, hemp, and flax have been used in the engineering production field. Natural fiber composites are used increasingly in the aerospace and automotive industries. Nowadays, natural fiber composites and artificial composites are being compared by researchers to find the most appropriate materials for engineering fields. Researchers are also more focused on natural fibers due to their biodegradability and low production cost. Assessments of the materials used in aircraft parts and panel structures have been made to study the potential of using natural fiber composites instead.

Abstract:

In this study, the fire resistance performance of high-strength concrete columns was evaluated to see the influence of lateral confinement reinforcement with wire ropes for improving ductility, fire resistance reinforcement with fiber cocktail and load ratio. For this, loaded fire test was conducted under ISO834 standard fire condition. The axial ductility of the 60MPa high-strength concrete column reinforced with pre-stressed wire ropes was improved and its fire resistance performance was also improved by 23% compared with its counterpart without wire ropes. The appropriate load for the 60MPa concrete column reinforced with wire ropes was found to be 70% of design load. The fire resistance performance of the 100MPa high-strength concrete column reinforced with pre-stressed wire ropes and fiber-cocktail was improved as much as 4 times compared with that reinforced with tie bars only. The appropriate load for the 100MPa columns was found to be less than 70% of design load in order for the columns to secure required fire resistance performance.

The effectiveness of externally applied fiber-reinforced polymer (FRP) ropes made of carbon fibers in X-shape formation and in both sides of the joint area of reinforced concrete (RC) beam–column connections is experimentally investigated. Six full-scale exterior RC beam–column joint specimens are tested under reverse cyclic deformation. Three of them have been strengthened using carbon FRP (CFRP) ropes that have been placed diagonally in the joint as additional, near surface-mounted reinforcements against shear. Full hysteretic curves, maximum applied load capacity, damage modes, stiffness and energy dissipation values per each loading step are presented and compared. Test results indicated that joint sub assemblages with X-shaped CFRP ropes exhibited improved hysteretic behavior and ameliorated performance with respect to the reference specimens. The effectiveness and the easy-to-apply character of the presented strengthening technique is also discussed.

Abstract:

The utilization of synthetic materials stimulates environmental concerns, and researchers worldwide are effectively reacting to environmental concerns by transitioning towards biodegradable and sustainable materials. Natural fibers like jute and sisal have been being utilized for ages in several applications, such as ropes, building materials, particle boards, etc. The absence of essential information in preparing the natural-fiber-reinforced materials is still a challenge for future applications. Chemical treatments and surface modifications can improve the quality of the natural fibers. Natural-fiber-based composites are a potential candidate for many lightweight engineering applications with significant mechanical properties. In the view of the progressive literature reported in the field, this work aims to present the significance of natural fibers, their composites, and the main factors influencing these materials for various applications (automotive industry, for instance). Secondly, we aim to address different surface modifications and chemical treatments on natural fibers and finally provide an overview of natural fiber reinforced polymer composites’ potential applications.

Abstract:

Sisal fiber is an important agricultural product used in the manufacture of ropes, rugs and also as a reinforcement of polymeric or cement-based composites. However, during the fiber production process a large amount of residues is generated which currently have a low potential for commercial use. The aim of this study is to characterize the agricultural residues by the production and improvement of sisal fiber, called field bush and refugo and verify the potentiality of their use in the reinforcement of cement-based composites. The residues were treated with wet-dry cycles and evaluated using tensile testing of fibers, scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy. Compatibility with the cement-based matrix was evaluated through the fiber pull-out test and flexural test in composites reinforced with 2 % of sisal residues. The results indicate that the use of treated residue allows the production of composites with good mechanical properties that are superior to the traditional composites reinforced with natural sisal fibers.

Abstract:

Fibers extracted from Amazonian plants that have traditionally been used by local communities to produce simple items such as ropes, nets, and rugs, are now recognized as promising composite reinforcements. This is the case for guaruman (Ischinosiphon körn) fiber, which was recently found to present potential mechanical and ballistic properties as 30 vol% reinforcement of epoxy composites. To complement these properties, Izod impact tests are now communicated in this brief report for similar composites with up to 30 vol% of guaruman fibers. A substantial increase in impact resistance, with over than 20 times the absorbed energy for the 30 vol% guaruman fiber composite, was obtained in comparison to neat epoxy. These results were statistically validated by Weibull analysis, ANOVA, and Tukey’s test. Scanning electron microscopy analysis disclosed the mechanisms responsible for the impact performance of the guaruman fiber composites.

Abstract:

Fique fibers, native to Colombia, are traditionally used for ropes and bags. In the extraction of long fibers for these purposes, the same amount of short fibers is generated; the short fibers are then discarded in the soil or in landfills. This agro-industrial waste is cellulose-rich and can be potentially developed into new biobased products. As an alternative use for these fibers, viscose regenerated fibers with potential applications in the textile industry were developed. Fique waste fibers were pulped (to produce fique cellulose pulp, FCP) using a 33 design of experiment (DOE) to adjust the variables of the whitening treatment, and DOE analysis showed that time and hydrogen peroxide concentration do not have a significant effect on non-cellulosic remotion, unlike temperature. The behavior of this pulp in the production of viscose was compared against that of commercially available wood cellulose pulp (WCP). FCP showed a suitable cellulose content with a high degree of polymerization, which makes it a viable pulp for producing discontinuous viscose rayon filaments. Both pulps showed the same performance in the production of the viscose dope and the same chemical, thermal, and mechanical behavior after being regenerated.

Abstract:

Abaca, also known as Manila hemp, is native to the Philippines, where it is grown as a commercial crop. It belongs to the Musasea family and is cultivated for ropes and fibers. The abaca fiber is a natural fiber with highest cellulose content. In this study, the effects of alkali treatments on mechanical properties and microstructure of abaca fibers are discussed. Abaca fibers were soaked in the aqueous solution of sodium hydroxide at the concentration from 3 to 15wt% for 5 minutes, and subsequently subjected to tensile tests and observations by scanning electron microscopy (SEM) to assess morphological changes caused by the alkali treatment. Fourier transform-infrared spectroscopy analysis demonstrated that the treatment led to the gradual removal of lignin and hemicelluloses from the abaca fibers. The cellulose crystallinity of abaca fibers was analyzed by an X-ray diffraction method. SEM images revealed that the lumen size decreased and shrunk with increasing alkali concentration. The tensile strength of the alkali-treated abaca fibers was higher than that of the untreated ones. The Young’s modulus increased with increasing alkali concentration up to 7wt% and then decreased. However, the strain at break decreased below 7wt% and then increased. The lumen size started to decrease from 7wt% alkali concentration.

Abstract:

Composites reinforced with natural lignocellulosic fibers (NLFs) are gaining relevance as the worldwide demand for renewable and sustainable materials increases. To develop novel natural composites with satisfactory properties, less common NLFs should also be investigated. Among these, the Cyperus malaccensis (CM), a type of sedge fiber, is already used in simple items like ropes, furniture, and paper, but has not yet been investigated as composite reinforcement for possible engineering applications. Therefore, the present work evaluated for the first time the properties of novel epoxy composites incorporated with 10, 20, and 30 vol.% of CM sedge fibers. Tensile, Izod-impact, and ballistic impact tests were performed, as well as Fourier transform infrared (FT-IR) spectroscopy and thermal analysis of the composites. Results disclosed a decrease (−55%) in tensile strengths as compared to the neat epoxy. However, the elastic modulus of the 30 vol.% sedge fiber composite increased (+127%). The total strain and absorbed ballistic energy did not show significant variation. The Izod impact energy of the 30 vol.% composite was found to be 181% higher than the values obtained for the neat epoxy as a control sample. An increase in both stiffness and toughness characterized a reinforcement effect of the sedge fiber. The thermal analysis revealed a slight decrease (−15%) in the degradation temperature of the CM sedge fiber composites compared to the neat epoxy. The glass-transition temperatures were determined to be in the range of 67 to 81 °C.

Abstract:

This research presents the structural design and mechanical performance evaluation results of a lightweight belt for high-rise elevators. Weight reduction of elevator components is indispensable in developing ultra-high-rise elevators. In this study, the structural design and performance evaluation of high-rise elevator ropes were carried out. The weight of the newly designed Carbon Fiber Reinforced Plastic (CFRP) belt was reduced by 30% compared with the original steel wire rope. The structural analysis results of the CFRP belt showed that the design criteria were met on the design load condition of the belt. Also, mechanical tests were executed to verify the mechanical characteristics of the newly developed belt, with the results showing that the belt had sufficient structural performance compared with conventional steel wire rope.
