EXPERIMENTAL INVESTIGATION ON FLEXURAL BEHAVIOR OF REINFORCED FOAM SANDWICH BEAMS WITH TWO-WAY LATTICE-WEB
摘要
Abstract
Composite sandwich structure has the characteristics of high specific strength,high specific stiffness,good designability and corrosion resistance etc.Two-way lattice-web reinforced foam core sandwich beams are prepared through vacuum assisted resin infusion,with polyurethane foam as the core,Glass Fiber Reinforced Polymer (GFRP) as the panels and lattice webs.In order to study the failure mode and mechanism,a series of three point bending tests were performed on the common foam sandwich beams and the lattice-web reinforced foam sandwich beams with different web height and web space.Based on the equivalent cross model of foam filled with rectangular honeycomb shape,the bending stiffness and the deflection of the specimens are predicted,and the calculated values agree well with the experimental values.关键词
