摘要： An invention for securing a boss (40) to a thermoplastic liner (12) of a pressure vessel (10) is disclosed. A preferred method of forming the vessel (10) includes inserting a thermoplastic projection (32) of the liner (12) into a mounting aperture (52) located in the boss (40). The projection (32), which is rigidly attached to the liner (12), mechanically prevents rotation of the boss (40) about a pressure chamber orifice (18) relative to the liner (12). The method further includes melting and compressing the thermoplastic projection (32) to conform it to a locking chamber (54) in the mounting aperture (52). A composite case is then constructed over the thermoplastic projection (32), the liner (12), and the boss (40), using the liner (12) as a mandrel. The thermoplastic liner (12) and projection (32) are integrally formed by blow-molding thermoplastic material into a die (64) without any substantial use of injection-molding. A vessel constructed according to the method is also disclosed.
