【摘要】：以600 tex玻璃長(zhǎng)絲束為經(jīng)紗,2 000 tex玄武巖長(zhǎng)絲束為緯紗,試織了3種不同梁高的T字形三維整體機(jī)織物,并采用VARTM(Vacuum Assistant Resin Transfer Moulding)成型工藝制備成復(fù)合材料。測(cè)試了3種T字形三維整體機(jī)織復(fù)合材料的沖擊性能。結(jié)果表明,梁高為12 mm的材料吸收能量最多,受到的沖擊強(qiáng)度最大;梁高為0 mm的材料吸收能量最少,受到的沖擊強(qiáng)度最小。不同梁高的T字形三維機(jī)織復(fù)合材料的破壞模式也各不相同。
[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,增強(qiáng)復(fù)合材料T字形結(jié)構(gòu)主要靠纖維鋪層來(lái)實(shí)現(xiàn),T字梁不僅制作工藝繁瑣,缺乏平行伸直的紗線增強(qiáng),且沒(méi)有厚度方向的紗線增強(qiáng),在受到剪切載荷作用時(shí),極易發(fā)生斷裂分層。T字形三維整體機(jī)織復(fù)合材料與二維層狀復(fù)合材料相比,具有層間強(qiáng)度高、耐沖擊損傷等優(yōu)點(diǎn)[1-3]。楊彩云[6]介，
