Abstract

Lowvelocityballisticimpactexperimentswerecarriedoutforcompositearmorsystem, whichwascombinedwithcompositelaminatesatthefrontandhomogeneoussteelplatesattheback. Failuremodesandenergyabsorbingmechanism wereanalysed.Ballistic-resistancewascomparedbetweenthecompositelaminatesandhomogeneoussteelplates. Basedontheexperiments,anequation wasobtainedtopredicttheresidualvelocityfortheperforationofcombinedtargetsaccordingtofailuremodes. Resultsshowthattheunitareadensityenergyabsorbingofthecompositelaminatesisfar moregreaterthanthatofhomogenoussteelplates.Failuremodesofthefrontalcompositearmorsof combinedtargetsaremainlyfabrictensilerupture.However,thefailuremodesofthesteelbacking platesaremostlypetalingbecauseoftheinfluenceofthefrontalcompositearmors.Itisshownthat thetheoreticalpredictionsareingoodagreementwithexperimentaldata.
