PRESSURE CONTAINMENT COMPONENT FOR AIRCRAFT SYSTEMS

Abstract:

The disclosure describes a pressure containment component of a pressurized system of an aircraft. The pressure containment component includes a dimensionally complex monolithic body defining an inlet and an outlet. The monolithic body includes a polyether ether ketone (PEEK) matrix and carbon fibers distributed throughout the PEEK matrix. The monolithic body is configured to contain a pressure greater than or equal to about 20 kPa from the pressurized system. The disclosure also describes a method of forming a pressure containment component of a pressurized system of an aircraft. The method includes injecting a thermoplastic mixture into a mold for a monolithic body of the component. The thermoplastic mixture includes a molten PEEK and carbon fibers distributed throughout the molten PEEK. The method includes cooling the thermoplastic mixture to form the monolithic body.
