<p>A method of bonding a rubber substrate to an epoxy resin based substrate which is particularly suitable for constructing selected components of rocket motors such as motor cases. The subject method includes disposing an acrylate between the substrates to be bonded together. The interfacial layer preferably has at least one rubber constituent and at least one acrylate therein. The disclosed method is particularly suitable for, but not limited to, bonding an unvulcanized EPDM rubber substrate to an aliphatic type epoxy resin based composite substrate containing fibrous reinforcement elements such as graphite or carbon fibers. Upon disposing the disclosed interfacial layer between the substrates to be bonded, the substrates are preferably co-cured at an elevated temperature to complete the bonding thereof. A preferred bonding compound including at least one rubber constituent, an acrylate constituent, and an optional hydrocarbon solvent for facilitating mixing and applying the compound to form an interfacial layer between the rubber substrate and the epoxy based substrate to be bonded together is also disclosed.</p> |
