THE EFFECT OF NONWOVEN REINFORCEMENT ON FLEXURAL STRENGTH OF GLASS, CARBON AND HYBRID COMPOSITES

This study examines the effect of nonwoven polypropylene veils on the flexural strength (3 and 4-point) of various layers of glass, carbon, and hybrid (glass and carbon) composite structures. The eight layers of the composite structures were manufactured using the vacuum infusion method with woven glass and carbon fabrics in various layer configurations. The flexural strength and elongation of the composites were found to be effectively influenced by the placement and number of nonwoven polypropylene reinforcement veils in the multilayer composite material.
