Resistance to Penetration and Compression of Fibre-Reinforced Composite Materials

Abstract

Tests on ballistic penetration, quasi-static and dynamic constrained compression tests and tensile tests are reported for glass-reinforced plastic (GRP), Kevlar(R), nylon and polyethylene composites. Sectioning of tested samples allowed deformation mechanisms to be studied. Ballistic penetration is associated with fibre tensile failure and ballistic 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 on composite type and differences can exist between dynamic and static tests on identical specimens. Energy absorption in penetration of organic-fibre composites is by fibre stretching. Penetration of GRP composites involves fibre and matrix crushing and extrusion.
