Abstract
Members for a rocket nozzle and a fabrication method thereof, wherein members for a rocket nozzle stacked in order of: a heat-resistant element; a first adhesive which is a thermosetting room temperature-hardening epoxy resin; a second adhesive which is a thermoplastic resin; a third adhesive which is a thermosetting medium temperature-hardening epoxy resin; and a structural body. The fabrication method according to the present invention comprises stacking a first adhesive, which is a thermosetting room temperature-hardening epoxy resin, on a surface of a heat-resistant element; stacking a second adhesive, which is a thermoplastic resin, on the first adhesive; stacking a third adhesive which is a thermosetting medium temperature-hardening epoxy resin, on the second adhesive and thereafter performing a vacuum shaping process; and stacking a structural body on the third adhesive and thereafter hardening the members.
