This　article　proposes　a　composite　buffer　based　on　two　characteristics:　porous　throttling　and　damping　energy　dissipation　of　entangled　metal　wire　material　(EMWM).　A　series　of　quasi-static　tests　and　low-speed　impact　tests　were　carried　out　to　analyze　its　stiffness　and　damping　characteristics.　The　filling　degrees　of　cushioning　force　curves　and　energy　absorption　rate　were　proposed　as　quantitative　evaluation　indicators　for　the　composite　buffer　under　low-speed　impact.　Test　results　showed　that　the　stiffness　and　damping　of　the　composite　buffer　layer　increase　with　the　increasing　density　of　the　EMWM　damping　layer　under　quasi-static　conditions,　but　the　static　loss　factor　fluctuates.　Under　low-speed　impact　load,　the　composite　buffer　demonstrates　stable　force　output,　with　an　energy　absorption　rate　above　85%　and　favourable　filling　degrees.　This　work　provides　a　practical　reference　for　its　engineering　application.
