Abstract
In order to get a strong, stiff and lightweight structure, a novel glass fiber reinforced composite (GFRC) lattice sandwich panel (LSP) was designed and manufactured. The lattice core consists of orthogonal corrugated GFRC truss and foam cubes. A modified vacuum assisted resin infusion (VARI) method was used to manufacture the LSP. Flatwise compression test, theoretical analysis and finite element analysis were carried out to reveal the modulus and failure modes of the structure. A local buckling failure and delamination at the corner of strut were observed in compression. Experimental, theoretical and simulation result show great agreement with each other on the modulus of the structure. The experimental modulus and ultimate failure strength are about 1.798Â GPa and 5.59Â MPa, respectively.
