Sandwich composite laminates structure is a classic application of composite material on actual aircraft structural. Dealing with low-velocity impact damage and residual compressive strength of sandwich composite laminates, explicit finite element method of ABAQUS/Explicit software was adopted to simulate low-velocity impact and compression process. Impact response and invalidation on compression between sandwich composite laminates with different core materials and regular composite laminates were compared. The simulation results indicated that softer core materials can absorb more impact energy, reduce the structure damage and enhance the residual compressive strength after impact.

Abstract Low velocity impact response (LVIR) of glass reinforced polymer composites (GRPCs), which have the potential to self repair both micro- and macro-damage, has been investigated. This class of materials falls under the category of passive smart polymer composites. The self-repairing mechanism is achieved through the incorporation of hollow fibers in addition to the normal solid reinforcing fibers. The hollow fibers store the damage-repairing solution or chemicals that are released into the matrix or damaged zone upon fiber failure. Plain-weave S-2 glass fabric reinforcement, DERAKANE vinyl ester 411-C50 and EPON-862 epoxy resin systems were considered for this study. Different tubing materials were investigated for potential use for storing the repairing chemicals instead of the actual hollow repair-fibers and included borosilicate glass micro-capillary pipets, flint glass Pasteur pipets, copper tubing and aluminum tubing. Composite panels were fabricated by using vacuum assisted resin transfer molding (VARTM) process. The present investigation addressed fabrication of self-repairing composite panels, the processing quality, selection of storage material for the repairing solution and, release and transportation of repairing solution.
