Method for producing an at least partially contoured, fibre reinforced plastic profile, a contoured, fibre reinforced plastic profile and its use

A method for producing an at least partially contoured, fiber-reinforced plastic profile comprising:

• providing a plurality of first reinforcing fibers,
• combining the first reinforcing fibers to produce a uni-, bi-, or tridirectional fiber bundle,
• impregnating the fiber bundle with a first plastic matrix,
• performing at least partial shaping or at least partial shaping and at least partial curing of the first plastic matrix to produce a fiber-reinforced plastic base element,
• providing a plurality of second reinforcing fibers for at least partial application to the fiber-reinforced plastic base element, wherein the second reinforcing fibers are shorter in length than the first reinforcing fibers,
• passing the fiber-reinforced plastic base element through an impregnation unit filled with a mixture of the second reinforcing fibers and a liquid second plastic matrix to apply the mixture of second reinforcing fibers impregnated with the liquid second plastic matrix to the fiber-reinforced plastic base element at least in regions for profiling,
• passing the fiber-reinforced plastic base element with the mixture of second reinforcing fibers and the liquid second plastic matrix through a stripping unit,
• supplying the fiber-reinforced plastic base element provided with the second reinforcing fibers to a unit for at least partial fiber-reinforced profiling and/or shaping where the fiber-reinforced plastic base element is at least partially profiled and/or shaped to produce an at least partially contoured, fiber-reinforced plastic strand, and
• cutting the at least partially contoured, fiber-reinforced plastic strand to produce an at least partially contoured, fiber-reinforced plastic profile.
