Abstract
A method for forming a composite propulsion system case includes providing a liner, bonding a thermoplastic film layer to the liner using an adhesive, and, subsequent to bonding the thermoplastic film layer to the liner, depositing a thermoplastic composite material onto the thermoplastic film layer to form an outer shell of the composite propulsion system case. The outer shell extends circumferentially about an axial centerline of the composite propulsion system case. The outer shell forms an outer radial surface of the composite propulsion system case.

- subsequent to bonding the thermoplastic film layer to the liner, depositing a thermoplastic composite material onto the thermoplastic film layer to form an outer shell of the composite propulsion system case, the outer shell extending circumferentially about an axial centerline of the composite propulsion system case, the outer shell forming an outer radial surface of the composite propulsion system case.
A composite propulsion system case comprising:
- a liner, a thermoplastic film layer, and a composite outer shell extending circumferentially about an axial centerline of the composite propulsion system case;
- the liner forming an inner radial surface of the composite propulsion system case, the liner including an elastomeric material body extending between and to an outer liner side and an inner liner side;
- the thermoplastic film layer extending between and to an outer film side and an inner film side, the inner film side disposed on the outer liner side, the thermoplastic film layer including a first thermoplastic material;
- and
- the composite outer shell disposed on the outer film side, the composite outer shell forming an outer radial surface of the composite propulsion system case, the composite outer shell including a second thermoplastic material and a fiber reinforcing material.
