Abstract:The aim of this work was to determine the fl exural properties of hybrid composites parts cut from trapezoidal core made of carbon/glass fi bers impregnated in epoxy resin with help of fi lament 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 fi ber reinforced plastic (FRP) laminates exhibit progressive failure consisting of fi ber failure, debonding, and delamination.Further, the paper investigates the content of voids inside the structure, the interface fi ber/epoxy resin using scanning electron microscope and the procedures involved in the laminate design, fabrication, experiments and analysis of composite part for decks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
