Abstract

Two-dimensional(2D)plain-wovenC/SiCcompositeplatesandduralumin (LY12)plates wereimpactedbymylar-filmflyerplateswhichwereloadedbyanelectricalgunto3.4-9.5m/s,respectively. Thefreeinterfacialvelocitiesoftheexperimentalplates were measured withalaser Dopplervelocimeterandtheimpact-induceddebriscloudswerecollectedwithpreparedfoamplates. Andthedamageareasoftheexperimentalplateswereinspectedbyusinganultrasonicscanningsystem. Basedontheaboveexperimentalresults,themechanicalresponsesofthe2Dplain-wovenC/SiC compositesunderhypervelocityimpactwereanalyzed.Theaboveexperimentalresultsshowthatwith theincreaseoftheimpactintensity,thefreeinterfacialvelocitiesofthe2Dplain-wovenC/SiCcompositeplatesincrease, thelocaldamageareasincrease,andthedebrisclouds-affectedregionsinthe preparedfoamplatesincrease.AndcomparedwiththeLY12platessubjectedtotheimpactofthe sameintensity,theintensitiesofthedebriscloudsfromthe2Dplain-wovenC/SiCcompositeplates arelower,theiraffectingregionsinthefoamplatesarelarger,andtheareicimpactenergiesarelower.
