Responses of materials of honeycomb structures with ceramic insertions against a long-rod tungsten projectile

摘要：

　　The penetration resistance of hybrid honeycomb structures with ceramic insertions against a vertical long-rod tungsten projectile was studied by artillery-launched experiments.These hybrid honeycomb structures were fabricated using titanium alloy, AISI 4340 steel and 7075 aluminum alloy panels,respectively, with rectangular honeycomb cores in transverse orthogonal arrangement and slide-fitting ceramic inserts of zirconia toughened alumina prisms.The results showed that the penetration resistance of the targets reduced when the titanium alloy honeycomb structure is replaced by 7075 aluminum alloy or AISI 4340 steel with the same area density.The underlying mechanisms showed that the hybrid structure made of titanium alloy had the highest penetration resistance owing to a good constraint condition for ceramic prisms by metallic webs and a strong back support.
