Abstract

Abstract: The vacuum introduction molding process is used to prepare a two-way lattice web reinforced foam sandwich composite beam with polyurethane foam as the core material and glass fiber reinforced composite material as the panel and lattice web. The quasi-static compression performance test and comparative analysis of ordinary foam sandwich beam and lattice web reinforced foam sandwich beam are carried out. The results show that compared with ordinary foam sandwich beams, the compression resistance of the lattice web reinforced foam sandwich beam has been significantly improved. Through theoretical deduction, the quasi-static compression expression of the lattice web reinforced foam sandwich composite beam is obtained. And compared with the experiment, the results are consistent.

Key words: lattice web, quasi-static compression, foam sandwich, composites
