PARTICULARITIES CONCERNING THE CHARPY TESTS OF COMPOSITE MATERIALS REINFORCED WITH WOVEN FABRICS

Abstract

The paper analyses the effects of the type of reinforcement on the impact characteristics in case of two composite materials reinforced with woven fabrics made of E-glass fibres. Therefore, two kinds of reinforcements were used to manufacture the composite materials: the first composite was reinforced only with glass woven fabrics while the other one composite was additionally reinforced with fir wood flour. The volume ratio of E-glass fibres was the same for each composite analysed. The paper presents and analyses the results of the Charpy tests (failure energy U and resilience K) in case of the composite materials tested. Some important remarks concerning the failure areas of the specimens are presented. Finally, the paper graphically shows the effects of the type of the reinforcement on the dynamical characteristics obtained in Charpy test.
