Patent number: 8771567Abstract: A process for producing fiber preforms for composite material components makes it possible to directly produce complex geometries in a flexible and low-cost manner by applying a plurality of dry fiber rovings independently of one another even in spatially uneven contours. It is no longer necessary to use cut fabric strips since fiber preforms are produced straight from the dry fiber rovings. This obviates the need to carry out production, transport and order picking processes. It is not necessary to cut fiber 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 fiber webs. The described process can also readily be scaled since the number of dry fiber rovings arranged next to one another make it possible to vary the area which can be covered.Type: GrantFiled: October 13, 2010Date of Patent: July 8, 2014Assignees: Airbus Operations GmbH, Toho Tenax Europe GmbHInventors: Joachim Piepenbrock, Carsten Barlag, Pierre Zahlen, Bernd Wohlmann, Markus Schneider
