At the same time, some defects are pointed out: present fabrics are not properly applied, and most of looms can't produce woven perform whose property is similar in different directions. Their shearing strength are lower, utilization of mechanical properties are also smaller;Although three-dimensional braided composites is of excellent integrated structure, normal braided fiber is traveled from internal to external surface, which is passed through braider and becomes three-dimensional structure. If the external surface is cut or rubbed , it's possible for the fiber to break down. In addition , the shape of perform is easily changed after it's finished . To deal with respective shortcomings and highlight their own advantages, we're searching a new weaving method which is the combination between weaving and braiding .
但它们各自也具有许多缺点:目前机织物适应性不够,大多数织机还不能加工三维各向同性的机制预型件,材料剪切性能较低,力学性能利用率低;三维编织复合材料虽然具有良好的结构整体性,但常用的编织都是纤维从内表面穿到外表面,即穿过编织件的断面成三维结构,用这种方法制成的结构,如果外表面受到摩擦或切割损伤,就有可能导致结构的解体,此外编织结构的织物易变形,所以我们需要考虑一种新的结构,能同时发挥各自优势,又能同时克服二者缺点,这就是机织与编织结构相结合的方法。
