1. A prepreg comprising a fibrous reinforcement and a curable epoxy resin mixture comprising an epoxy resin having an epoxy equivalent weight of from 150 to 1500 and from 0.5 to 10 weight percent of a urea based curing agent, based on the total weight of said epoxy resin mixture, said urea curing agent being the only curative in said epoxy resin mixture, said epoxy resin mixture being curable by an externally applied temperature in the range of 70° C. to 110° C. |
