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 dual protection inner seal washer employs a radially outward metallic portion having a dielectric coating and a radially inward polymeric portion engaging the metallic portion at an interface with an interference fit. The polymeric portion has at least one tapering compression surface to engage a surface of a structure proximate a hole and further has a fastener element contact surface to engage a mating surface on a fastener system element. Torqueing of the fastener element compresses the at least one compression surface inducing a predetermined pressure in the polymeric portion in a joint created by the fastener element and structure.

Abstract: A system and method for testing a material system may include a support structure for mounting the material system, and a electromechanical device operably connected to the support structure, wherein the electromechanical device applies an electromechanical-induced force to the material system, and wherein the electromechanical-induced force causes a displacement in the material system equivalent to material displacement from thermal stress in significantly less time.

Abstract: A method for installing a fastener by positioning a cap around the fastener, spraying a cooling agent from a sprayer of a cooling system. The fastener may have a top portion including a dielectric material. The cooling system may be configured to cool the top portion of the fastener to stiffen the top portion. A tool may be configured to install the fastener in a structure after cooling, while retaining the cooling agent within the cap.
