Abstract：

B4C/Al　is　a　novel　composite　material　with　metals　and　ceramics.　Compared　with　traditional　ceramic　materials,　B4C/Al　has　been　widely　used　in　the　protective　armour　due　to　the　advantages　of　low　density,　high　hardness,　high　toughness,　and　low　cost.　In　order　to　research　the　mechanical　properties　of　B4C/Al　composites　under　dynamic　loading,　the　waveforms　of　the　materials　under　different　impact　speeds　and　the　fracture　morphology　under　micro　environment　were　obtained　through　split　Hopkinson　pressure　bar　(SHPB)　testing　and　scanning　electron　microscope　(SEM).　And　the　stress-strain　curve　characteristics　and　failure　modes　of　the　materials　under　different　strain　rates　were　studied.　Furthermore,　the　influence　of　Al　content　on　the　dynamic　compressive　strength　of　the　material　was　analysed.　The　results　can　provide　reference　for　the　design　and　application　of　B4C/Al　composites.　©　2022　Rare　Metals　Materials　and　Engineering　Press.　All　rights　reserved.
