Use of an adhesive tape in a method for joining two fibre-reinforced plastic components, comprising the following steps: • producing a first fibre-reinforced plastic component by introducing a laid scrim of fibre mats which is impregnated with a resin/curing agent mixture, which in turn is subsequently cured in the absence of air; that part of the surface of the first fibre-reinforced plastic component which is later to be bonded to the second fibre-reinforced plastic component (also called joining surface below) is masked with an adhesive tape before the fibre mats are impregnated with the resin/curing agent mixture, • producing a second fibre-reinforced plastic component according to the steps specified above; that part of the surface of the second fibre-reinforced plastic component that is later to be bonded to the first fibre-reinforced plastic component is likewise masked with an adhesive tape before the fibre mats are impregnated with the resin/curing agent mixture, • removing the adhesive tapes from the two completed fibre-reinforced plastic components, • contacting the two joining surfaces, • introducing a resin/curing agent mixture between the two joining surfaces, • curing the resin/curing agent mixture, wherein the adhesive tape comprises a carrier material made of polyethylene, said carrier material bearing on one side a polyacrylate-based self-adhesive composition, which can be traced back to the following reactant mixture, comprising monomers of the following composition: A1) acrylic esters and/or methacrylic esters of the following formula CH2=CH(R 1) (COOR 2) where R 1 = H or CH 3 and R 2 is an alkyl chain having 1 to 14 carbon atoms, with a fraction of 65 to 98 wt%, A2) acrylates and/or methacrylates whose alcohol component contains at least one primary hydroxyl or carboxyl group, and/or vinyl compounds which are copolymerizable with acrylates and which contain at least one primary hydroxyl or carboxyl group, with a fraction of 1 to 20 wt%, A3) polyfunctional isocyanate crosslinkers which are blocked with thermally reversible protecting groups, with a fraction of 1 to 10 wt%, A4) and, if the fractions of A1), A2) and A3) do not add up to 100 wt%, olefinically unsaturated monomers having functional groups, with a fraction of 0 to 15 wt%. • producing a first fibre-reinforced plastic component by introducing a laid scrim of fibre mats which is impregnated with a resin/curing agent mixture, which in turn is subsequently cured in the absence of air; that part of the surface of the first fibre-reinforced plastic component which is later to be bonded to the second fibre-reinforced plastic component (also called joining surface below) is masked with an adhesive tape before the fibre mats are impregnated with the resin/curing agent mixture, • producing a second fibre-reinforced plastic component according to the steps specified above; that part of the surface of the second fibre-reinforced plastic component that is later to be bonded to the first fibre-reinforced plastic component is likewise masked with an adhesive tape before the fibre mats are impregnated with the resin/curing agent mixture, • removing the adhesive tapes from the two completed fibre-reinforced plastic components, • contacting the two joining surfaces, • introducing a resin/curing agent mixture between the two joining surfaces, • curing the resin/curing agent mixture, wherein the adhesive tape comprises a carrier material made of polyethylene, said carrier material bearing on one side a polyacrylate-based self-adhesive composition, which can be traced back to the following reactant mixture, comprising monomers of the following composition: A1) acrylic esters and/or methacrylic esters of the following formula CH2=CH(R 1) (COOR 2) where R 1 = H or CH 3 and R 2 is an alkyl chain having 1 to 14 carbon atoms, with a fraction of 65 to 98 wt%, A2) acrylates and/or methacrylates whose alcohol component contains at least one primary hydroxyl or carboxyl group, and/or vinyl compounds which are copolymerizable with acrylates and which contain at least one primary hydroxyl or carboxyl group, with a fraction of 1 to 20 wt%, A3) polyfunctional isocyanate crosslinkers which are blocked with thermally reversible protecting groups, with a fraction of 1 to 10 wt%, A4) and, if the fractions of A1), A2) and A3) do not add up to 100 wt%, olefinically unsaturated monomers having functional groups, with a fraction of 0 to 15 wt%.
