摘要
Abstract
High performance fiber woven fabric can be utilized as blast-resistant structural material for impro-vised explosive devices(IEDs)in the cabin of civil aviation aircraft.In some cases,explosive devices are enhanced with fragments to increase their destructive effect.To evaluate the protective performance of fiber woven fabrics under blast loads with fragments,this research conducted free-field blast experiments with secondary fragments on aramid(Aramid)and ultra-high molecular weight polyethylene(UHMWPE)plain weave fabrics.Additionally,overpressure sensors and high-speed cameras were employed to record the experimental process.The failure behavior of the fab-rics was analyzed through theoretical analysis of shockwave and fragment propagation and experimental results.It was observed that the high-velocity fragments accelerated by the blast shockwave altered the blast loading character-istics,and resulted in changes to the fabric's failure modes.At close stand-off distance(SOD),the shockwave impacts the fabric before the fragments,and the preloading of the shockwave deteriorates the fragment-resistance of the fabric.The results indicate that:under the same charge,thicker fabrics are required to provide complete protec-tion against blast shockwave and fragments.Therefore,enhancing the fragment-resistant properties of fiber fabrics will be a focal point for improving protective performance in subsequent research.关键词
