摘要：

A reduced temperature epoxy formulation for repair of epoxy-graphite composite laminates was characterized. The epoxy formulation comprised selected high functionality aromatic epoxy resins and a multi-component polyamine curing system containing an elastomeric toughener. Experimental results for bonding graphite-epoxy specimens have shown that, compared with a 175-degrees-C commercial film adhesive, the proposed formulation has better low temperature shear strength, comparable ambient properties and lower elevated temperature (120-degrees) shear properties. The epoxy formulation exhibits the same in-plane shear modulus as the commercial material and a plastic behavior at high shear strains. Consequently, the fatigue endurance of the epoxy formulation has been found to be superior to that of the 175-degrees-C commercial film adhesive.
