报告摘要：

Novel lightweight foam based sandwich structures are made from thin-skins and core with embedded composite reinforcement. The skin materials are usually made from high strength alloys, glass or carbon fibre reinforced composites, whilst the core is usually made from PVC foam, thermoplastic polyurethane, carbon fibre lattices, SLM lattice, composite egg box, etc., with possible embedded composite or metal tubes. Such sandwich structures maximise compression resistance offered by material as well as restraints to composite tubes from the foam. Throughout optimised design on blast and impact resistance, this type of sandwich structures can be produced with the optimised energy absorption to weight ratio. Also, they can be used in manufacturing train carriage components, mobile houses, super structures of ships.
