Abstract:In order to analyze the mechanical properties and energy absorption effect of foam-filled sandwich composite materials reinforced specimens, quasi-static compression experiments were carried out. The Glass fiber reinforced polymer(GFRP) was used on the surface and lattice webs of the specimen, and polyurethane(PU) foam was used for core material. The specimens prepared from these two materials include hexagonal (H) lattice and trapezoidal (T) lattice. The experiment results show that the load displacement curve of 45 º trapezoidal lattice specimen is the most ideal. The specimen not only avoids the problem of sudden drop of bearing capacity, but also greatly improves the elastic stroke. For hexagonal lattice specimens, the increase of foam density has great influence on the elastic ultimate bearing capacity and energy absorption characteristics of specimens. Based on the stress analysis of the matrix element intercepted by the trapezoidal lattice specimen, the equivalent compressive elastic modulus of the 45 ° trapezoidal lattice specimen is obtained. Based on the compression experiment of ANSYS / LS-DYNA simulation specimen, the simulation results are in good agreement with the experiment values. Finally, through the collision simulation of ship anti-collision device pier, it is found that the trapezoidal lattice composite anti-collision device has a greater reduction of ship collision force and better anti-collision protection performance.
