Abstract

The invention relates to an adhesive tape which can be used in particular in a method for connecting two fiber-reinforced plastic components, comprising a carrier material made of polyethylene, wherein a polyacrylate-based self-adhesive compound is applied to one side of the carrier material, said adhesive compound can be reduced to the following reactant mixture containing monomers having the following composition: A1) acrylic acid ester, and/or methacrylic acid ester of the following formula CH═CH(R)(COOR), wherein R=H or CHand Ris an alkyl chain with 1 to 14 carbon atoms at a proportion of between 65 to 98 wt. %, A2) acrylates and/or methacrylates whose alcohol component contains at least one primary hydroxyl- or carboxyl-group, and/or with acrylate-copolymerizable vinyl compounds containing the at least one primary hydroxyl or carboxyl group at a proportion of between 1 to 20 wt. %, A3) multi-functional isocyanate cross-linker which blocks with thermally reversible protective groups at a proportion of between 1-10 wt. %, A4) and, if the proportions 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. %.
