In　order　to　enhance　concrete＇s　impact　resistance,　this　study　investigates　the　effects　of　single　basalt　fiber　and　basalt-polyethylene　hybrid　fiber　on　concrete　through　split　Hopkinson　pressure　bar　(SHPB)　tests,　emphasizing　their　significance　in　engineering　applications.　A　comparative　analysis　of　the　failure　modes,　dynamic　compressive　strength,　dynamic　compressive　toughness,　and　dynamic　growth　factor　of　specimens　was　conducted　under　different　strain　rates　and　polyethylene　fiber　volume　fractions.　The　study　considered　concrete　damage,　strain　rate　effect,　and　the　toughening　effect　of　fibers,　introducing　the　damage　factor,　and　establishing　a　dynamic　damage　constitutive　model　for　fiber-reinforced　concrete.　The　results　showed　that　basalt-polyethylene　fiber　reinforced　concrete　(BPFRC)　exhibited　better　impact　resistance　and　deformation　capability.　There　were　improvements　observed　in　dynamic　compressive　strength,　dynamic　compressive　toughness,　and　dynamic　growth　factor.　The　addition　of　basalt　fiber　(BF)　and　polyethylene　fiber　(PE)　played　a　buffering　role　in　inhibiting　crack　propagation　and　slowing　down　the　damage　process.　The　optimum　PE　volume　fraction　for　dynamic　compressive　strength　was　0.1%　at　a　strain　rate　of　60　s−1,　0.15%　at　a　strain　rate　of　95　s−1,　and　0.05%　at　a　strain　rate　of　120　s−1,　all　with　a　BF　volume　fraction　of　0.25%.　The　optimum　fiber　volume　fractions　for　dynamic　compressive　toughness　and　dynamic　peak　toughness　were　consistent,　both　at　0.25%　BF　and　0.1%　PE.　The　established　dynamic　damage　constitutive　model　for　fiber-reinforced　concrete　can　effectively　describe　the　impact　resistance　performance　of　BPFRC,　and　the　experimental　curves　fit　well　with　the　constitutive　curves.　Furthermore,　it　was　observed　that　BF　acted　as　macrofibers,　bridging　to　restrain　the　post-hardening　cracking　of　concrete,　while　PE　acted　as　microfibers,　inhibiting　the　propagation　of　plastic　cracks,　reducing　internal　defects　in　concrete,　and　enhancing　the　ductility　and　toughness　of　concrete.　Consequently,　BPFRC　holds　significant　potential　value　in　engineering　applications.　©　2023
