Comparison of Mechanical Properties of Unidirectional and Woven Carbon, Glass and Aramid Fiber Reinforced Epoxy Composites

Abstract

In this study, mechanical behavior of epoxy composite reinforced by unidirectional and woven fiber is investigated experimentally. In the preparation of composite samples woven shaped glass, aramid and carbon fibers and unidirectional shaped glass and carbon fibers were used. Tension, compression and shear tests were carried out to determine mechanical properties of composites. It is seen from the test results, that unidirectional carbon fiber shows better performance than the glass fiber. Mechanical properties of 0• -oriented unidirectional fiber are better than those of 90• -oriented unidirectional fiber. Mechanical properties of aramid-fiber-reinforced composite are higher than those of glass and carbon fiber, when the woven types of fibers are considered.

The Mechanical Properties of Kevlar Fabric/Epoxy Composites Containing Aluminosilicates Modified with Quaternary Ammonium and Phosphonium Salts

“…During the bending of continuous fiber reinforced composites, the composite is compressed and tensioned. Polymer composites, in particular aramid fiber composites, are characterized by the weak transverse properties [ 44 , 45 ] and significantly lower compression compared to tension strength [ 46 ]. As a result, the bending strength depends primarily on the compressive strength, as the damage usually starts on the compressive side [ 30 ].…”

Electrical and Mechanical Performance of Hybrid and Non-hybrid Composites

“…Braga et al [11] demonstrated the mechanical properties and the microstructure of hybrid jute-glass /epoxy composites and found that the physical and mechanical properties of this hybrid were significantly improved. Tensile and shear properties of epoxy composite reinforced by two different types of fibers, unidirectional (glass and carbon) and woven fibers (glass, aramid and carbon), were investigated [12]. Tensile properties of aramid fiber of the woven type are higher than that the glass and carbon fibers.…”
