Abstract:

In order to reveal failure mechanism and failure mode of glass fiber/epoxy resin sandwich composite under side compressive load, a meso-structural model was built by using the finite element software ANSYS, and numerical simulation of side compressive properties on the composite was analyzed emphasisly. The stress and strain distribution of the composite, fibers and resin was discussed under side compressive loads of 3 mm displacement by using the meso-structural model. The results show that when the composite is subjected to side compressive load, the maximum value of stress occurs on the upper and lower face-sheet macroscopically, where the composite is damaged easily. The minimum value of stress occurs on the piles, where the composite is hard to be damaged. Unstable failure easily occurs on the face-sheet between two rows piles, which is the main failure cause of the composite. The fibers play a major role in bearing, and the resin plays a minor role microscopically. The failure mode is the resin fracture, and the interfacial de-bonding between fibers and resin when the composite is loaded with 3 mm displacement compression.

Key words: glass fiber/epoxy resin sandwich composite, numerical simulation, side compressive properties, failure mechanism, failure mode
