【摘要】:以600 tex玻璃长丝束为经纱,2 000 tex玄武岩长丝束为纬纱,试织了3种不同梁高的T字形三维整体机织物,并采用VARTM(Vacuum Assistant Resin Transfer Moulding)成型工艺制备成复合材料。测试了3种T字形三维整体机织复合材料的冲击性能。结果表明,梁高为12 mm的材料吸收能量最多,受到的冲击强度最大;梁高为0 mm的材料吸收能量最少,受到的冲击强度最小。不同梁高的T字形三维机织复合材料的破坏模式也各不相同。
[Abstract]:Using 600 tex glass filament beam as warp yarn and 2 000 tex basalt filament beam as weft, three kinds of T shaped 3D woven fabrics with different beam heights were experimentally woven. VARTM(Vacuum Assistant Resin Transfer Moulding was used. The impact properties of three T-shaped 3D monolithic woven composites were tested. The material with a beam height of 12 mm absorbs the most energy and receives the greatest impact strength. The material with a beam height of 0 mm absorbs the least energy and receives the least impact strength. The failure modes of the T-shaped 3D woven composites with different beam heights are also different.

【正文快照】: 目前,增强复合材料T字形结构主要靠纤维铺层来实现,T字梁不仅制作工艺繁琐,缺乏平行伸直的纱线增强,且没有厚度方向的纱线增强,在受到剪切载荷作用时,极易发生断裂分层。T字形三维整体机织复合材料与二维层状复合材料相比,具有层间强度高、耐冲击损伤等优点[1-3]。杨彩云[6]介,
