Title: The Innovative Contributions of Steven M Motoyama
Introduction
Steven M Motoyama is a notable inventor based in Phoenix, AZ, recognized for his significant contributions to the field of composite manufacturing. With a focus on creating advanced hollow composite structures, he has developed a unique method that enhances the efficiency and quality of these materials.
Latest Patents
Motoyama holds a patent for a "High pressure hollow process for manufacturing composite structures." This innovative method fabricates complex hollow composite structures from laminates of fiber-reinforced synthetic resins. The resulting structures are fully monocoque tubes with no seams, manufactured by wrapping a hollow semi-rigid inner mandrel made of thermoplastic material, such as polystyrene or ABS, with layers of composite sheets. These sheets consist of high-strength fibers impregnated with thermosetting or thermoplastic resins. The laminated mandrel is then placed in a mold, heated, and inflated to a predetermined pressure, which can range from 20-200 psig and even higher. The curing temperature can vary from 200°F to 600°F. This process generates a highly consolidated composite structure with fewer voids, a more uniform thickness, and increased fiber content compared to other fabrication methods.
