Title: Innovations of Stephen S. Tompkins
Introduction
Stephen S. Tompkins is a notable inventor based in Williamsburg, VA (US). He holds 2 patents that showcase his contributions to the field of materials science and engineering. His work primarily focuses on enhancing the properties of composite materials through innovative methods and materials.
Latest Patents
One of his latest patents is for "Poly(arylene ether imidazole) surfacing films for flat and parabolic." This invention involves films made from thermoplastic poly(arylene ether imidazole)s (PAEI) that serve as surface modifiers for resin panels. The PAEI polymer features imidazole groups that chemically react with epoxies or bismaleimides during processing, ensuring excellent adhesion between the film and the resin. The resulting film not only provides a smooth surface but also acts as a release agent from molds, eliminating the need for additional release agents. The film is thermally stable, resistant to electron radiation, and maintains strong adhesion even after thermal cycling from room temperature to approximately -196°C.
Another significant patent by Tompkins is the "Method of thermal strain hysteresis reduction in metal matrix composites." This method addresses the issue of thermal strain hysteresis in graphite reinforced metal matrix composites. By applying a specific heat treatment followed by cryogenic treatment, the method effectively imparts dimensional stability and reduces thermal strain hysteresis across a wide thermal cycle range of -250°F to +250°F.
