Composition comprises at least a curable structural adhesive, and at least a chemically crosslinked elastomer, where the elastomer is present as a penetrating polymer network in the structural adhesive. Independent claims are included for: (1) a method for preparing the composition comprising mixing the epoxy resin A with the curing agent B, adding and mixing the curing agent H, reacting the epoxy resin A with the curing agent H, or mixing the epoxy resin A with the curing agent H and B, reacting the epoxy resin A with the curing agent H at a temperature below the activation temperature of the curing agent B; (2) a molded body, which is subjected to a reversible molding process comprising heating the composition to a temperature above its glass transition temperature, molding the composition under the tension of chemically crosslinked elastomer, and cooling the molded composition below its glass transition temperature; and (3) a reinforcement element for reinforcing cavities in structural components comprising a carrier at which the molded body is mounted. |
