Abstract: A method for molding amorphous polyether ether ketone including steps of preparing a molten mass including polyether ether ketone, cooling a mold assembly to a temperature of at most about 200° F., and injecting the molten mass into the cooled mold assembly.

Abstract: A method of installing a decompression panel assembly in an aircraft. The decompression panel assembly includes a body portion, a baffle member, and a panel member. The method includes coupling the body portion to the panel member, wherein the body portion includes a plurality of frame members defining a plurality of openings in the body portion. The method also includes coupling the baffle member to the plurality of frame members such that the baffle member removably obstructs at least one opening of the plurality of openings. The baffle member is integrally formed with the plurality of frame members and is configured for at least partial displacement from the at least one opening during a decompression event. The decompression panel assembly is then coupled between a sidewall and a floor panel of the aircraft.

Abstract: Test systems for simulating an environment for erosion testing. An exemplary system includes a wind tunnel having a fan unit at one end and an exhaust unit at the other, and a test fixture that secures a specimen under test in a path of the air flow created in the wind tunnel. The system also includes a water injection unit installed between the fan unit and the test fixture that emits water droplets into the air flow. A controller of the system identifies a test profile indicating conditions for a test of the specimen, and varies the speed of the air flow, the orientation of the specimen, and/or a flow rate of water out of a nozzle of the water injection unit during the test to simulate the conditions indicated in the test profile.
