Abstract: Adhesive tape useful in a method for connecting two fiber-reinforced plastic components, wherein a polyacrylate self-adhesive is applied to one side of a polyethylene carrier, the polyacrylate self-adhesive being formed from a reactant mixture of A1) 65 to 98 wt. % acrylic acid ester, and/or methacrylic acid ester monomers of the formula CH2═CH(R1)(COOR2) wherein R1=H or CH3 and R2 is an alkyl chain with 1 to 14 carbon atoms, A2) 1 to 5 wt. % acrylates and/or methacrylates whose alcohol component contains at least one primary hydroxyl- or carboxyl group and/or with acrylate-copolymerizable vinyl compounds containing at least one primary hydroxyl or carboxyl groups, A3) 1 to 5 wt. % acrylates and/or methacrylates whose alcohol component contains at least one epoxy group, and/or with acrylate-copolymerizable compounds containing the at least one epoxy group and, if A1, A2, and A3 to not total 100%, A4) 0 to 15 wt. % olefinically unsaturated monomers.

Abstract: An adhesive tape useful in a method for connecting two fiber-reinforced plastic components, comprising a carrier material of polyethylene, a polyacrylate-based self-adhesive compound applied to one side of the carrier material, being formed from a reactant mixture comprising monomers of A1) acrylic esters and/or methacrylic esters of the formula CH2═CH(R1)(COOR2), 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, A3) acrylates and/or methacrylates whose alcohol component contains at least one epoxy group, and/or vinyl compounds which contain at least one epoxy group, 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 proportion of 0 to 15 wt %.

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.
