PROCESS FOR PRODUCING FIBRE PREFORMS |
摘要 |
The process for producing fibre preforms for composite material components according to the present invention makes it possible to directly produce complex geometries in a flexible and low-cost manner by applying a plurality of dry fibre rovings independently of one another even in spatially uneven contours. It is no longer necessary to use cut fabric strips since fibre preforms are produced straight from the dry fibre rovings. This obviates the need to carry out production, transport and order picking processes. It is not necessary to cut fibre strips to size, and therefore a saving may be made on material. In addition, it is possible to increase the mechanical characteristic values in the composite material because it is not necessary to sew fibre webs. The described process can also readily be scaled since the number of dry fibre rovings arranged next to one another make it possible to vary the area which can be covered. In addition, it is advantageous that the dry fibre rovings are fixed directly in the process.
