摘要:
A plurality of unidirectional sheets (30a, 30b, 30c) are superposed in different directions and they are bonded together. At least one of the unidirectional sheets is made by spreading a tow so as to obtain uniform thickness, width not less than 5 cm, and a weight of no more than 300 g/m2, cohesion being imparted to the sheet so as to enable it to be handled prior to being superposed with other sheets. Advantageously, the unidirectional sheets are made of carbon fibers and are obtained by spreading out large tows.
摘要(中):
多个单向片材(30a,30b,30c)在不同方向上重叠,并且它们结合在一起。 单向片材中的至少一个是通过铺展丝束制成的,以获得均匀的厚度,宽度不小于5cm,重量不超过300g / m 2,赋予内聚力 以使其能够在与其他片材重叠之前被处理。 有利地,单向片由碳纤维制成,并且通过展开大的丝束获得。
