Abstract:
The invention relates to a method for connecting two fibre-reinforced plastic components, comprising the following steps: producing a first fibre-reinforced plastic component, wherein a fabric made of fibrous matting is provided, which is impregnated with a resin-curing agent mixture, which is then subsequently cured, wherein the part of the surface of the first fibre-reinforced plastic component, which is to be later adhered to the second fibre-reinforced plastic component (hereinafter also referred to as joining surface), is masked with an adhesive strip before the impregnation of the fibrous matting with the resin-curing agent mixture; producing a second fibre-reinforced plastic component using the above steps, wherein the part of the surface of the second fibre-reinforced plastic component, which is to be later adhered to the first fibre-reinforced plastic component, is also masked with an adhesive strip before the impregnation of the fibrous matting with the resin-curing agent mixture; removing the adhesive strips from the two finished fibre-reinforced plastic components; bringing the two joining surfaces in contact; introducing a resin-curing agent mixture between the two joining surfaces; curing the resin-curing agent mixture, wherein the adhesive strip has a carrier film, on one side of which an adhesive mass, in particular self-adhesive mass is applied, and wherein the carrier film consists of fluoropolymers, polyethylene polymers, undrawn polypropylenes or of metal, and the adhesive mass is an acrylate or silicon adhesive mass.
