1. A method for producing a fibrous composite material component comprising the following steps:
applying a binder to a dry woven fabric layer,
reshaping the dry woven fabric layer into a preform layer, wherein the binder is activated and stabilizes the woven fabric,
following the reshaping step, applying the preform layer to further woven fabric layers using adhesive, thereby constituting a preform,
inserting the preform into a molding tool for carrying out a resin-transfer-molding (RTM) process, and
carrying out the RTM process such that the preform is a visible layer of the fibrous composite material component.
