Abstract: This invention relates quite in general to production of fiber composite components by infiltration of a fiber material with a synthetic resin and subsequent curing. In order to improve the required preparation of a liquid or viscous resin system, as claimed in the invention especially a synthetic resin granulate (10, 12) and a process for its production are provided, encompassing the step of stabilization of the synthetic resin granulate (10?) by adding nanoparticles (12?) which attach on the surface of the granulate particles (10). The granulate (10, 12) which is thus free of blocks can be easily handled, for example bagged, flow-conveyed and metered. Advantageously the nanoparticles do not have an adverse effect on the infiltration properties of the resin and on the component properties.
