Experimental investigation of low-velocity impact on woven glass-fibre-reinforced plastics composites

Abstract

This study describes the experimental investiga-tion of low-energy drop-weight impact tests on woven glass-fiber-reinforced composites. The test program consisted of drop weight impact tests for the determination of the absorbed energy for the impact damage and the influence of impact energy, varied between 6 and 28 J, on damage area development. The most of the energy absorbtion of the composite laminates appeared to be the result of delamination and fibre break-age. Absorbed energy and damaged area of woven- and multiaxial non-crimpe fabric composites was compared.
