Process for the production of fiber-reinforced composite materials with stabilized fibers, fiber coatings and / or fiber bundle coatings

摘要

The present invention relates to a method for producing fiber-reinforced composite materials with stabilized fibers, fiber coatings and / or fiber bundle coatings. In the method, a fiber preform is provided which comprises reinforcing fibers, the reinforcing fibers each being coated with at least one coating and / or the reinforcing fibers being arranged in bundles which are each coated with at least one coating. Convex particles that contain or consist of at least one material that is identical to a material of the reinforcing fibers and / or to a material of the at least one coating of the reinforcing fibers and / or to a material of the at least one coating of the bundles are introduced into the fiber preform . During and / or after the introduction of the convex particles into the fiber preform, the fiber preform is infiltrated with a melt. According to the invention, the radius of curvature of the convex particles is smaller than the radius of curvature of the reinforcing fibers. In this way, the reinforcement fibers, reinforcement fiber coatings and / or reinforcement fiber bundle coatings can be stabilized. The present invention also relates to a fiber-reinforced composite material with stabilized fibers, fiber coatings and / or fiber bundle layers.
