Abstract:

Carbon fibers (also known as graphite fibers) are high-performance fibers, about five to ten micrometers in diameter, composed mainly of carbon, with high tensile strength. Plus, they are extremely strong with respect to their size. They have high elastic modulus in comparison with glass fiber. According to the working period, carbon fibre-reinforced polymers possess more potential than those with glass fiber. However, they are relatively expensive as compared to similar fibers, such as glass fiber, basalt fiber, or plastic fiber. Its high quality, lightweight, and imperviousness to erosion, m

The question of adhesion of fibers with a cement matrix is considered. Under certain conditions the fibers connect and hold the places of potential breaks.

Since plain concrete is brittle by nature, the flexural and split tensile strengths developed must be taken into consideration. Plain concrete is robust in solidity; nevertheless, with feeble cutting-edge tautness. Numerous fibres are commonly utilized in the construction sector to enhance concrete's flexural strength, ductile strength and durability properties. The great tensile strength of steel fiber makes it the fiber of choice for usage in the building industry. However, steel fibre has some disadvantages, including a propensity for corrosion.

In this research, kenaf fiber bundles have been treated by both alkaline sulfide and a modified chemical degumming methods to improve fiber properties.

Abstract:

This study presents a multiscale characterization of flax fibers, from elementary fibers to technical bundles and yarns, to elucidate how fiber scale attributes influence yarn mechanics. Four yarn counts (111.11 tex, 100 tex, 90.9 tex, and 83.33 tex) were produced via dry spinning, and tensile testing performed at each structural level. The results revealed a progressive decline in a specific modulus from elementary fibers (1.09 ± 0.62 N/tex) to short bundles (14.41 ± 9.59 N/tex), primarily due to fiber misalignment. Post hoc analysis confirmed that finer yarns (83.33 tex) exhibited higher sti

The present work deals with the effect of water absorption on the mechanical properties of untreated, 10% alkali-treated, and 10% alkali plus 1% silane treated sisal fibers (5%, 10%, and 15%) reinforced polyester composites. Hand lay-up was used to create the composite. The samples were prepared in accordance with ASTM standards, and tests for tensile strength, flexural strength, impact strength, and water absorption were performed. An increase in the tensile, flexural and impact strength was observed with an increase in fibre loading for untreated, alkali-treated and alkali plus silane treate

Polyactic fibers have superior biodegradability, moisture absorption, resiliency and processibility and can be used in various fields especially in blood filtration. Polyactic can be melt blown into nonwoven fabrics. To predict the fiber diameter of the polyactic melt blown nonwoven fabric, the air drawing model of polyactic was established. The predicted fiber diameter tallies well with the measured fiber diameter. Computer simulations of the effects of the processing parameters on the fiber diameter were performed with the help of the air drawing model. The simulation results show that small

An important factor that determines progress of a country is the transportation network. One of the basic components of transportation is pavement. In most countries especially in India, pavements are in bad condition. This is mainly due to poor maintenance of the road, use of low- quality material, etc. The defects like potholes appear on a pavement when it loses its ability to transfer the traffic load to subgrade. The transportation sector is growing continuously. This causes a drastic increase in the number of vehicles which causes an increase in traffic load. The existing pavements are no

Aluminum matrix composites reinforced with carbon fiber have been manufactured for the first time by infiltrating an A413 aluminum alloy in carbon fiber woven using high-pressure die casting (HPDC). Composites were manufactured with unidirectional carbon fibers and with 2 × 2 twill carbon wovens. The HPDC allowed full wetting of the carbon fibers and the infiltration of the aluminum alloy in the fibers meshes using aluminum at 680 °C. There was no discontinuity at the carbon fiber-matrix interface, and porosity was kept below 0.1%. There was no degradation of the carbon fibers by their reactio

AbstractThe focal ratio degradation (FRD) of optical fibers is a major source causing light loss to astronomical multi-fibre instruments like LAMOST (Oliveira, A. C, et al. 2005). The effects of stress and twist during mounting and rotation of the fibers could change the FRD for individual fibers (Clayton 1989), which means that the transmission efficiency of each individual fiber will vary. We investigate such throughput variation among LAMOST fibers and its relevance to the intensity of sky emission lines (Garstang 1989) over the full wavelength coverage.

The effects of fiber shape on the mechanical responses of fiber assemblies under compression, tension, and shear deformations are numerically investigated using the discrete element method (DEM). Simulations of the compression of ring-shaped fibers are consistent with experimental results, verifying the discrete element method code. In the compressive tests of S-shaped fibers, pressure exhibits a nonmonotonic dependence on fiber curvature; while in the tensile tests, yield tensile stress generally decreases with increasing fiber curvature. In the shear tests, yield shear stress decreases with

A novel approach by rapid prototyping and rapid tool technique (RP/RT) was used in this paper to fabricate fibre-reinforced CPC composite artificial bone. The subsequent mechanical experiments demonstrated that the compressive strength of the CPC-fiber artificial bone was 24MPa, which was significantly higher than 6MPa for
