Abstract
Analyses of impact resistance are made for composites reinforced with fibers of high modulus aramid, glass, graphite, and graphite/high modulus aramid hybrids which indicate that the aramid fiber offers advantages over the other materials in thin laminate specimens when measured by Charpy, Izod, and ball drop impact tests while retaining some structural integrity. Use of the high modulus aramid fiber as a hybrid with graphite resulted in higher impact energy resistance than the all-graphite fiber composite.
The fracture characteristics of notched quasi-isotropic high modulus aramid, E-glass, and A-S graphite epoxy lamina and of notched fabric epoxy lamina of aramid and of glass are analyzed. Aramid showed the highest fracture resistance, followed by glass and graphite.
