Abstract:Grid-scored foams are core materials adapted to resin infusion systems used in marine vessels and aerofoil shell structures of wind turbine blades. Perforation resistance is critical in such constructions, and so the goal of this research is to analyse the energy absorption ability of sandwich composites with grid-scored foam core. Grid-scored foam contributed more to the energy absorption capacity of sandwich structures due to causing higher contact force compared with rigid foam under low-speed and quasi-sta… Show more
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.
