  • Patent number: 11453147
    Abstract: At least one surface of a FRP component is coated by impregnating a structure formed with textile fibres with a flowable polymeric matrix material so the fibres are completely covered to form the coating, a thickness of the flowable polymeric matrix material above the fibres of at least 100 ?m and at least one ply of pull-off fabric, mesh or gauze is laid on and wetted or impregnated completely with the flowable polymeric matrix material. The polymeric matrix material is cured then the at least one ply of pull-off fabric, mesh or gauze is removed by peeling and in this region a surface of increased roughness is obtained so between the surface of increased roughness and fibres there is a layer formed with the cured polymeric matrix material, having a thickness of at least 100 ?m. Coating the increased roughness surface with a thermal spraying process.
