Abstract
A study of the intermediate velocity impact of composites is presented with reference to the use of low-cost processing methods such as vacuum-assisted resin transfer moulding, (VARTM) in order to address the process-performance relationships to various loading threats. Carbon graphite fibre composites are susceptible to impact damage because of their poor impact resistance, and are the focus of the present work. An evaluation is reported of the intermediate velocity impact response of two commonly used structural carbon fabric laminates produced from plain and 2/2 twill woven fabrics, processed using VARTM. All carbon/epoxy laminates were covered with a polycarbonate facing in order to enhance impact resistance. The perforation mechanism, ballistic limit, and damage evolution of each laminate is discussed. 14 refs.
