摘要/Abstract

摘要： 釆用高强低伸工业涤纶为原料,加工织造了机织间隔织物,对间隔织物空间进行泡沫填充,面层与树脂进行复合,制成了三明治型复合材料板材。测试了冲击位置不同时复合板材耐冲击性能和冲击前后板材的侧压性能,分析了冲击位置对三明治型复合板材耐冲击性能的影响。结果表明,相同冲击能量作用下,冲击位置不同时,复合板材的表观破坏和冲击后侧压性能均有差异。在间隔织物规格相同的情况下,冲击位置在接结点处的板材表观冲击损伤大,但冲击发生在接结点处的板材受冲击后,所能承受的侧压载荷相对较大。

关键词: 机织间隔织物, 三明治型复合板材, 冲击位置, 冲击性能, 侧压性能

Abstract: The high-strength low-stretch industrial polyester filaments were used to manufacture the woven spacer fabric, which was filled with foam between the two surface layer. Then, the surface layer was composited with resin to make the sandwich composite panels. Impact test was performed at different positions on the composites and the sidewise compression property of the panels was tested before and after impacting to analyze the influence of impact positions on the impact property of the composite panels. The experiment results indicated that the visible impacting damage and side compression properties of panels after impacting were different when the impacting positions on the panels were different, even though the impacting energies were same. It was found that when the impact applied on the position of the binder yarn, the visible impacting damage was more obvious than that of the other positions. But the side compression loads of the panels impacted on the binder yarn were larger than that of panels impacted on other position.

Key words: woven spacer fabric, sandwich composite panels, impact position, impact property, side compression property
