He has made significant contributions to the field of materials science, particularly in the development of advanced polymeric materials. With a total of 2 patents, his work has implications for various applications in composite materials.
Latest Patents
One of his latest patents focuses on Poly(arylene ether imidazole) surfacing films for flat and parabolic surfaces. These films are made from thermoplastic poly(arylene ether imidazole)s (PAEI) and serve as surface modifiers for both neat resin panels and composite resin panels. The PAEI polymer features imidazole groups along its backbone, which chemically react with epoxies or bismaleimides during processing. This reaction ensures excellent adhesion between the PAEI film and the resin facesheet. The film not only provides a smooth surface to the finished part but also acts as a release agent from the mold. The resulting structures exhibit very smooth surfaces and do not require additional release agents due to the film's ability to release readily from glass molds. Furthermore, the PAEI 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 involves preparing polymeric matrix composites using an aqueous slurry technique. This innovative process allows for the creation of a consolidated composite laminate from an aqueous slurry. A poly(amic acid) surfactant solution is prepared by dissolving poly(amic acid) powder in an aqueous ammonia solution. A polymeric powder is then added to form a slurry, which is deposited on carbon fiber to create a prepreg. After drying and stacking, the composite laminate is consolidated under pressure and heated to form the polymeric matrix. The resulting laminate demonstrates high fracture toughness and excellent consolidation.
