摘要
为了解纺织结构复合材料的动态力学行为,更好地设计并应用纺织结构复合材料,对三维多重纬经角联锁织物复合材料的动、静态力学性能进行了测试。运用分离式Hopkinson压杆装置测试了不同速度(应变率)及准静态时材料的力学性能。结果表明:三维多重纬经角联锁织物复合材料是应变率敏感材料;随着冲击速度的不断提高,材料所能承受的载荷及吸收的能量增大;材料破坏时前面表现为压缩破坏形式,背面为拉伸破坏形式。
For understanding the dynamic mechanical properties of textile structural composites and better designing and application of them,both the static and dynamic mechanical properties of 3-D multi-layer weft interlaced with warp interlock woven fabric composite were tested with a modified split Hopkinson pressure bar(SHPB) apparatus.It was found that this fabric composite is stress sensitive.The bearing ability and energy absorption of the composite increase with the increase of compact velocity.The damage morphology of the composite manifests the compression failure on the face and tension failure on the back.
