Fiber Reinforced Polymer (FRP) bars are anisotropic in nature and have high tensile strength the fiber direction. The use of High-Strength Concrete (HSC) allows for better high-strength properties FRP bars. mechanical can yield to large crack widths deflections. As a result, design concrete elements reinforced with materials is often governed by Serviceability Limit States (SLS). This study inv...

Composite materials made of fiber-reinforced plastic laminates are highly susceptible to surface damage caused by wear during contour milling, especially with inappropriate tool and cutting material properties. Improper choice tools conditions lead delamination between applied layers, thermal in the polymer matrix, reduction edge quality tools. The study was devoted circumferential milling twil...

In this paper, the electromagnetic shielding characteristics of an up-to-date typical carbon filler material, carbon fiber used with a metal mesh were investigated. Carbon fiber 12k-prepregs, where carbon fibers were impregnated with epoxy, were laminated with wire meshes, vacuum bag-molded and hardened to manufacture hybrid-type specimens, with which an electromagnetic shield test was performe...

fiber reinforced composites are widely used instead of traditional materials in various technological applications. therefore, by considering the extensive applications of these materials, a proper knowledge of their impact behavior (from low- to high-velocity) as well as their static behavior is necessary. in order to study the effects of strain rates on the behavior of these materials, specia...

In this work, ozone modification method and air-oxidation are used for the surface treatment of polyacrylonitrile(PAN)based carbon fiber. The surface characteristics of carbon fibers are characterized by X-ray photoelectron spectroscopy (XPS). The interfacial properties of carbon fiber reinforced polyamide 6 (CF/PA6) composites are investigated by means of the single fiber pull-out tests. As a ...

In present work 2D FE (finite element) analysis of deformation and damage evolution site in fiber reinforced composites are carried out. The fiber cracking point and stresses is simulated in the fibers/matrix interface, using the ANSYS FE software at varying volume fractions. The effect of matrix cracks and the interface strength on the fiber failure is investigated. Multi-fibre model were used...
