Resumen
The ballistic behavior of multi-layer Kevlar
aramid fabric/polypropylene (PP) composite
laminate (CL) and plain layered aramid fabric (AF) impact specimens was investigated. It
was found that the thermoplastic PP matrix increases the ballistic performance of CL
targets when compared to AF targets with similar areal density, resulting in less aramid
fabric needed to obtain the same level of protection when the PP matrix is incorporated. It
was found that the improved ballistic performance of CL targets is due to the fact that the
thermoplastic matrix enables energy absorbing mechanisms such as fabric/matrix
debonding and delamination. The ballistic limit and penetration threshold energy of the CL
configurations, which were predicted using an empirical model, were found to be higher
than those of the AF targets. These results show that aramid fabric/PP laminates should be
further studied for improved ballistic performance at lower costs.
