Abstract
A leaf spring for a motor vehicle is made from a fiber composite component including individual fibers in form of at least two textile layers stacked on top of each other and a matrix made of a duroplastic or thermoplastic resin surrounding the fibers. The resin is hardened in a mold tool by applying pressure and heat. The stacked textile layers are formed inside a mold tool and fixed by a dry binder applied to at least one of the textile layers to form a dry preform. A fiber composite blank is stamped from the preform and subsequently infiltrated with the resin in a RTM cavity and hardened. The binder applied in dry form may only be arranged in certain areas of the textile layers.
