Experimental research of compressive responses of multi-layered woven textile sandwich panels under quasi-static loading

摘要: Abstract Multi-layered panels were manufactured by stacking thin monolayer to improve the energy absorption ability of woven textile sandwich. Quasi-static compression experiments conducted get stress–strain curves and reveal mechanism. For multi-layered staked 3 mm thickness, core piles experience strength failure; that renders panel high load resistance a strain-hardening curve before densification. The thickening would trigger stack buckle one after other, which decreases prolonged zigzag load–deformation curve. peak structure is found be close its constituting monolayer, but much greater than same thickness. deformation then becomes multiple process collapses. Energy greatly enhanced far exceeds
