多层复合舰用装甲结构抗高速破片特性比较研究

基于舰船舱壁防火、抗爆和抗高速破片冲击等综合防护需求,提出钢/陶瓷棉/FRp隔热对称式多层复合防护结构形式(简称MCFS结构).针对MCFS结构和钢/FRP对称式夹层结构(简称MFS结构)在高速(＞1000 m/s)破片模拟弹冲击下的损伤及吸能特性进行试验研究,结果显示,弹道冲击下MCFS结构的典型破坏模式为:前置钢板...

Energy Absorption Mechanism of MCFS Structure Impacted by High Velocity FSP

Under common demands of warship structure for fireproof,blastfroof and high velocity fragment resistance,the MCFS structure,a symmtrical multi-lays composite structure,which is made up of steel plate,heat insulation cushion and FRP,has been putted forward.The comparative experimental research for deformation and energy absorption property of MCFS and MFS(steel/FRP/steel sandwich) structures has been carried out.The experiment results show that the frontal steel plate has similar deformation model for the two structures.However,the deformation model of mid-lay FRP is different,the large deformation and heave of back face in MCFS and the ceramics cotton has little limit for the deformation of mid-lay FRP,but there is no visible deformtion cone in MFS.The ballistic experimental results show that the ability of fragments resistance and impact energy absorbing of MCFS is superior to MFS with the same weight per area.At the same time,the ballistic impact experiments for single steel target and single FRP laminates also have been done,the energy absorbing mechanism of MCFS is analysied on the base of experiments above.
