Abstract

A fiber reinforced resin matrix composite material repair system is provided, which critically employs a resin comprising a catalyst of the formula I: ##STR1## with a multifunctional epoxy resin, the resin system being sealed in a water-proofed environment prior to being coated onto a fiber reinforcement. The coated fiber reinforcement is applied over the damaged area, the damaged portion having been removed, and the surrounding surface smoothed. An adhesive is applied to the remaining surface, prior to application of the patch. The resulting patch, which may further include thermoplastic toughening agents and an enhancer, can be directly cured at temperatures below 212.degree. F. to give physical properties similar to the original material.
