Abstract:
1. Method for arming composite-fabrication to repair, reinforce or enhance stability of open-air located objects with unsaturated polyester/vinyl-ester resin based matrix-materials containing unidirectional oriented banded reinforcing materials in the form of freely deformable multi-layer composite bands, comprising: a) transferring an activator needed to harden a prepreg by diffusion from the polyester/vinyl-ester resin based adhesive material, b) applying the activator between consecutive layers of a coiled band of the prepreg, c) enhancing the matrix material's networking by decomposing peroxides mixed into the matrix at low temperature and d) solidifying the band in its entire thickness, wherein said adhesive comprises 30-50 m/m % of an unsaturated polyester resin and/or vinyl-ester resin; 1-10 m/m % of a (meth)acryl-acid-ester monomer; 1-5 m/m % of a thixatropic additive; 30-50 m/m % of aluminum-hydroxide and/or CaCO
