摘要: In this paper, a simple and innovative foam-filled lattice composite panel is proposed to upgrade the peak load energy absorption capacity. Unlike other foam core sandwich panels, kind of panels manufactured through vacuum assisted resin infusion process rather than adhesive bonding. An experimental study was conducted validate effectiveness for increasing strength. The effects web thickness, spacing density on initial stiffness, deformability absorbing capacity were also investigated. Test results show that compared foam-core maximum an approximately 1600% increase in strength can be achieved due use webs. Meanwhile, enhanced by thickness density. Furthermore, using webs, specimens had higher stiffness. A theoretical model developed predict ultimate panels.
