Fabric preforms undergo transverse compaction during composite manufacturing. This compaction changes the preform thickness, fibre volume fraction (FVF), tow geometry and voids for resin flow. In this paper, influence of yarn hybridisation and fibre architecture on the compaction response of woven fabric preforms has been studied. A series of cyclic compression tests have been carried out on both dry and wet preforms. The effect of hybridisation on compressibility has been investigated for single as well as multilayer fabrics. The influence of interlacement pattern (twill and satin fabrics) with hybrid yarns has also been investigated. Nesting efficiencies of multilayer stacks have been studied by utilising mechanical test results. Additionally, the meso-structure of single and multilayer fabrics under 1 bar pressure has been analysed using SEM images. It is observed that the thickness reduction for single layer twill hybrid fabric is 38% while thickness reduction for twill S-glass fabric is 67% at 100 kPa. Moreover, single layer hybrid twill fabrics have shown higher compressibility resistance (60% thickness reduction at 100 kPa) compared to single layer hybrid satin fabrics (which showed 67% thickness reduction at 100 kPa). Whereas opposite trend is observed for multilayer hybrid fabrics due to nesting effect.

纱线杂交和纤维结构对复合材料制造过程中机织物预制件压实响应的影响

织物预制件在复合材料制造过程中经历横向压实。这种压实改变了预成型件的厚度、纤维体积分数 (FVF)、丝束几何形状和树脂流动的空隙。在本文中,研究了纱线杂交和纤维结构对机织织物预制件压实响应的影响。已经对干和湿预制件进行了一系列循环压缩测试。已经研究了混合对单层和多层织物的可压缩性的影响。还研究了交织图案(斜纹织物和缎纹织物)与混合纱线的影响。已经通过利用机械测试结果研究了多层堆叠的嵌套效率。此外,使用 SEM 图像分析了单层和多层织物在 1 巴压力下的细观结构。据观察,单层斜纹混合织物的厚度减少了 38%,而斜纹 S 玻璃织物的厚度减少了 67%,在 100 kPa 下。此外,与单层混合缎纹织物(在 100 kPa 下厚度减少 67%)相比,单层混合斜纹织物显示出更高的抗压缩性(在 100 kPa 下厚度减少 60%)。而由于嵌套效应,多层混合织物观察到相反的趋势。与单层混合缎纹织物(在 100 kPa 下厚度减少 67%)相比,单层混合斜纹织物显示出更高的抗压缩性(在 100 kPa 下厚度减少 60%)。而由于嵌套效应,多层混合织物观察到相反的趋势。与单层混合缎纹织物(在 100 kPa 下厚度减少 67%)相比,单层混合斜纹织物显示出更高的抗压缩性(在 100 kPa 下厚度减少 60%)。而由于嵌套效应,多层混合织物观察到相反的趋势。
