Abstract
A method for joining together structural components made of composite material using a metal splicing member and for joining together a plurality of structural components to form a high-pressure containment vessel for cryogenic propellants. The method in its broadest sense entails a first step of forming plies from "green" composite material, a second step of arranging first and second stacks of the plies on opposite surfaces of the metal splicing member such that portions of the splicing member are captured between the first and second stacks of the plies, and a third step of curing said stacks of plies so that said composite material is co-bonded with said metal splicing member. The "green" plies and the metal splicing member are then subjected to temperatures and pressures sufficient to effect curing of the plies and attachment to surfaces of the splicing member. A variation of this process is disclosed in which cured plies are used.
