Abstract
Tests on ballistic penetration, quasi-static and dynamic constrained c ompression tests and tensile tests are reported for glass-reinforced p lastic (GRP), Kevlar(R), nylon and polyethylene composites. Sectioning of tested samples allowed deformation mechanisms to be studied. Balli stic penetration is associated with fibre tensile failure and ballisti c resistance correlates with tensile modulus. However, no correlation between the levels of fracture stress or fracture strain and ballistic resistance was found to exist. The mechanisms of deformation depend o n composite type and differences can exist between dynamic and static tests on identical specimens. Energy absorption in penetration of orga nic-fibre composites is by fibre stretching. Penetration of GRP compos ites involves fibre and matrix crushing and extrusion.
