Transverse impact resistance performance of the jet angle-interlock fabric composites

利用半自动小样织机织制不同组织结构的喷射口角联锁织物,再通过真空辅助树脂转移模型技术制成喷射口角联锁织物复合材料,对比它们的横向耐冲击性能。结果表明:对于不同结构、相同循环喷射口角联锁织物复合材料而言,可承受的冲击载荷方面,六层实口三循环喷射口角联锁织物复合材料最大、四层实口三循环喷射口角联锁织物复合材料优于四层空口三循环喷射口角联锁织物复合材料,能量吸收方面,六层实口三循环喷射口角联锁织物复合材料的能量吸收最大、四层空口三循环喷射口角联锁织物复合材料优于四层实口三循环喷射口角联锁织物复合材料;对于相同结构、不同循环喷射口角联锁织物复合材料而言,四层实口三循环喷射口角联锁织物复合材料可承受的冲击载荷及能量吸收都优于四层实口二循环喷射口角联锁织物复合材料。

The jet angle-interlock fabrics with different weaving structures were woven on the semi- automatic sample loom, and then the jet angle-interlock fabric composites were made with the vacuum assistanl resin transfer model technology. Their transverse impact resistance performance was compared. The results showed that, as far as the jet angle-interlock fabric composites with the same structures and different cycles were concerned, the bearable impact load of the 6-layer and 3-cycle full jet angle-interlock fabric composite was the best, the 4-layer and 3-cycle full jet angle-interlock fabric composite was better than the 4-layer and 3-cycle empty jet angle-interlock fabric composite, the energy absorption of the 6-layer and 3-cycle full jet angle-interlock fabric composite was the best, the4-layer and 3-cycle empty jet angle-interlock fabric composite was better than the 4-layer and 3-cycle full jet angle-interlock fabric composite; as far as the jetangle-interlock fabrics composites with the same cycles and different structures were concerned, the bearable impact load and tile energy absorption of the 4--layer and 3-cycle full jet angle-interlock fabric composite were both better than the 4-layer and 2-cycle full jet angle-interlock fabric eomposite.
