Abstract

Inordertoinvestigatetheanti-penetrationmechanismandtherelationshipbetweendynamic behaviorandanti-perforationperformanceoffiberreinforcedpolymercomposites(FRP),theexperimentwhichspherefragmentsimulatedprojectilespenetratecompositelaminateswasconductedto characterizetheanti-perforationabsorbingenergyproperty.Thecharacteristicofinstantaneousdeformationandfailurewasanalyzedbyhighspeedphotography, andtheanti-penetratingenergydissipationmodelofcompositelaminateswasinvestigatedbyCTandSEMscanningtechniquesandother methods.Theresultsshowthattheanti-perforationabsorbedenergyoflaminatesunderhighvelocity impactisproportionaltoimpactvelocity,theprocessofpenetratinglaminatesunderhighvelocityisa courseofdynamicdeformationunderhighstrainrateforcomposite,andthatdynamicmechanicalbehaviorunderhighstrainratehasaremarkableinfluenceontheanti- perforationabsorbedenergyof laminates.Atthesametime,thepropagatingcharacteristicofshockwavesinFRPdeterminedthe partitionofdifferentphaseoffailuremodel,anddeterminedthefailurezoneoflaminates.Basedon dynamicsinstantaneousanalysisofpenetratingprocessathighvelocity,thetwo-stagedynamicfailure modelofanti-perforatingabsorbedenergywasestablished,andthemodelagreedwellwiththeexperimentalresults.
