EFFECT OF LOADING SPEED ON DEFORMATION OF COMPOSITE MATERIALS: A CRITICAL REVIEW

Composite materials possess multiphase and by virtue of this have varied applications in the field of automotive, aerospace and defense industries. These applications demand high-impact loading at many instances, so the evaluation of the effect of impact loading on composite materials is important. Under high-strain loading, the composites mainly exhibit matrix properties but the variation arises when the amount of reinforcement is considered. The response of composite materials to high-strain loading for dilute concentration of reinforcement differs from that of highly populated reinforcement material. The loading speed refers to the crosshead velocity which has direct proportionality with strain rate. Loading speed is an experimental parameter which can be altered to study the crashworthiness of a material. This review report contains a brief review of literature on the effect of loading speed on the deformation history of polymer, metal and ceramic matrix composites.
