多层纬编增强结构因其优异的悬垂性、抗冲击性和近净成形可制造性而引起复合材料行业的兴趣。对这些结构的研究是德累斯顿工业大学纺织机械和高性能材料技术研究所的主要重点之一，从机械开发到整个生产链，考虑到使用过的高性能玻璃/丙纶混杂纱线的编织能力。这些面料结合了非卷曲面料和传统纬编面料的优点。由于水平(纬纱)和垂直(经纱)方向的直线镶嵌纱线，这些结构非常适合作为复合材料应用的增强结构，具有更好的机械性能。
Multilayer-weft-knitted reinforcing structures arouse interest in the composite industry for their excellent drapability, impact resistance, and near-net-shape manufacturability. The research into those structures is one main focus at the Institute of Textile Machinery and High Performance Material Technology at Technische Universitat Dresden starting from machine development up to the whole production chain, taking into account the knitting ability of the used high performance glass/ polypropylene hybrid-yarns. Those fabrics combine the advantages of non-crimp fabrics and conventional weft-knitted fabrics. Due to the straight inlay yarns in horizontal (weft) and vertical (warp) direction these structures ideally suit as reinforcing structures for composite application with improved mechanical properties.
