Patent ID: 8882956

Claim:
A method of bonding two parts together, the method comprising: placing the parts together with a layer of an interpenetrating polymer network (IPN) adhesive between the parts, the IPN adhesive contacting both parts, the parts comprising a metal part and a composite part, the composite part comprising a fiber reinforced polymer matrix; attaching the parts to each other by curing a first polymer system of the IPN adhesive using radiation energy, wherein the first polymer system is cured to a stage that allows handling of the parts; and thermally curing a second polymer system of the IPN adhesive after the first polymer system has been cured, wherein the second polymer system is selected from the group consisting of: bis(3,4-epoxy cyclohexylmethyl) adipate(BECA); and a combination of a diglycidyl ether of bisphenol A (DGEBA) with a polypropylene glycol diglycidyl ether (PPGDE) chain extender.
