Abstract

A method for producing a fibrous composite material component, in particular for a vehicle. According to the method, at least one dry woven fabric layer is initially provided, wherein the woven fabric layer includes carbon fibers. A binder is then applied to the woven fabric layer. Further, the woven fabric layer is reshaped into a preform layer, wherein the binder is activated during the reshaping and the woven fabric is stabilized in the reshaped shape. The preform layer is then applied to further woven fabric layers in order to strengthen the shape. The connection of the preform layer and the further woven fabric layers thus results in a preform, which is inserted into a molding tool for carrying out an RTM process. Then, the RTM process is carried out in order to obtain a fibrous composite material component.
