Abstract:

Polypropylene fibrous concrete is a new kind of composite material. Polypropylene fiber leads to an increase in the resisting strength, cracking resistance performance, resistance to impact performance and permeability reducing performance of the concrete, thus reduces the shrinking and deformation of the concrete. This paper uses the method of numerical analysis, assisted by the software of finite element analysis, makes both static and dynamic analysis on the polypropylene fibrous concrete ditch with different volume mixing. It results in the stress and strain table of the head and base plat

Abstract:

The paper presents the results of the development of the technology of centrifugal-die forming of biologically active fibrous materials. The modification of biologically active polypropylene fibers was carried out directly at the process of their production in the field of centrifugal forces of rotating reactor during their molding from polypropylene melt. The properties of the obtained ion-exchange and biologically active polymer fibers are studied. It is shown that obtained and modified by the centrifugal-die method polypropylene fibers can be used as biologically active fibers.

Wet electrostatic precipitators (wet ESPs) are good options for effective control of PM2.5 emission. However, the common problems of uniform water film formed on rigid collector limited the applicability of typical wet ESPs, thus could be tend to cause "spark-over" and "back-corona". This research was designed to test the performance of the polypropylene fibrous as collection electrodes for PM2.5 control in wet ESP. Meanwhile, drop spreading feature and volume resistivity measurements of polypropylene fibrous collector were investigated. The results show that drop spreading existed in imbibiti

Abstract:

In this study, polypropylene (PP) fibrous mats are modified by plasma treatment, following by chemical grafting. Initially, the as-prepared PP fibrous mats are treated by plasma at different oxygen (O2) and argon (Ar) ratios. Then, the PP fibrous mats are modified by grafting dopamine onto polar groups for in situ polymerizations, resulting in a polydopamine (PDA) coating on the substrate's surface. Time-sensitive wettability is thereby converted into permanent wettability in PP fibers. The morphology, chemical performance, and relative wettability of the modified PP fibers are then characteri

Abstract:

Based on the evaluation of fibrous concrete materials and the experiments of freezing-thawing resistance home and abroad, the present experiment takes relative dynamic modulus of elasticity and rate of mass reduction as an analytical index to conduct a comparative study on the effects of the mixing of four kinds of polypropylene fiber on the cement concrete freezing resistance. The results show that different kinds of polypropylene fiber have different influences on cement concrete freezing resistance. And some polypropylene can improve it while others may make it decreased.

At present, research on concrete-filled sections extends to using lightweight concrete to reduce the total weight of such structures. However, research on concrete-filled hollow sections (CFHS) using foamed concrete remains ongoing. Therefore, this study was conducted to determine the strength of reinforced fibrous foamed CFHSs. Two types of fibre, namely, steel and polypropylene fibres, were used. A short-column specimen was prepared and tested under compression load.

Abstract:

The use of natural fibers as reinforcement in thermoplastics presents an interesting alternative for the production of low cost and ecologically friendly composites. One of the advantages of using natural fibres is their low specific weight, resulting in higher specific strength and stiffness when compared to glass reinforced composites. Natural fibres also present safer handling and working conditions. They are non-abrasive to mixing and can contribute to significant cost reduction.

Traditionally ultrafine fibers below 1 dpf are produced by extrusion followed by mechanical drawing. A modified melt spinning apparatus with high-speed air nozzle was designed and fabricated to produce continuous polypropylene filaments by cold air drawing only. With this setup, the fiber is quenched and simultaneously attenuated by a symmetric cold air jet. Since the formation of fiber structure is highly dependent on the processing conditions, the new process will provide a unique operation window to study fiber attenuation and structural formation under high-speed cold air drawing.

Naturalfibres are inexpensive, renewable, biodegradable, present lowerdensity and their mechanical properties can be compared tothose of inorganic fillers. However, several disadvantagesappear when natural fibres are used for composites. First ofall, the poor compatibility between the hydrophilic fibres withthe hydrophobic thermoplastic matrix leads to a weak interface,which results in poor mechanical properties. On the other hand,the hydrophilic nature of the fibres makes them very

Rubberized cementitious composites are gaining focus in sustainable construction. Crumb rubber, sourced from waste tires, is used as a partial replacement for sand in concrete. However, rubber's low density, elasticity, and hydrophobic nature reduce workability and mechanical strength, owing to voids and poor compaction. To address these issues, supplementary cementitious materials (SCMs) like silica fume and fly ash, along with polypropylene (PP) fibres, were incorporated in this study.
