Abstract:
A method of repairing and reinforcing a preexisting structure, comprising the steps of:providing a reactive mixture which comprised as its chief components (1) a monomer having vinyl groups an (2) a reactive oligomer having vinyl groups and/or a thermoplastic polymer and has a gelling time of 15 minutes or more a 20Â° C., the polymerization of which is capable of being initiated even at a temperature of 5Â° C. and which is curable in a period of time of 6 hours or less, even at a temperature of 5Â° C.; applying the reactive mixture to the preexisting structure while impregnating a sheet material comprising reinforcement fibers with the applied mixture at a temperature at the place of use; and curing the reactive mixture to form a fiber-reinforced resin layer.
