Abstract

The aim of this work was to determine the flexural properties of hybrid composites parts cut from trapezoidal core made of carbon/glass fibers impregnated in epoxy resin with help of filament winding technology. Values for stress, strain and module of elasticity were calculated using three point bending test. The tests were performed according to American Society for Testing and Materials (ASTM) standards. Hybrid fiber reinforced plastic (FRP) laminates exhibit progressive failure consisting of fiber failure, debonding, and delamination.
Further, the paper investigates the content of voids inside the structure, the interface fiber/epoxy resin using scanning electron microscope and the procedures involved in the laminate design, fabrication, experiments and analysis of composite part for decks.
