IMPROVING METHOD FOR ADHESION AND SEALING PERFORMANCE OF EXIT CONE INSULATOR AND EXIT CONE OF ROCKET NOZZLE

摘要

The present invention relates to a material for a rocket nozzle laminated in a sequence of a heat-resistant material / thermosetting room temperature curing epoxy resin first adhesive / thermosetting resin second adhesive / thermosetting mesothermal curing epoxy resin third adhesive / structure in the order of will be. According to the method of the present invention, a first adhesive, which is a thermosetting room temperature curing epoxy resin, is loaded on a surface of a heat resistant material, a thermoplastic second adhesive is loaded on the first adhesive, and a third adhesive which is a thermosetting mesophilic curing epoxy resin on the second adhesive. After laminating, vacuum forming, and laminating an uncured carbon fiber / epoxy structure on the third adhesive, followed by curing.
