Title: Howard A. Lindsay: Innovator in Composite Manufacturing
Introduction
Howard A. Lindsay is a notable inventor based in Cordova, TN (US). He has made significant contributions to the field of composite manufacturing, particularly through his innovative patent that focuses on high-pressure hollow processes.
Latest Patents
Lindsay holds a patent for a method titled "High pressure hollow process for manufacturing composite structures." This invention details a technique for fabricating complex hollow composite structures from laminates of fiber-reinforced synthetic resins. The resulting structures are fully monocoque tubes without seams. The manufacturing process involves wrapping a hollow semi-rigid inner mandrel made of thermoplastic materials, 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 innovative process results in a highly consolidated composite structure with fewer voids, a more uniform thickness, and increased fiber content compared to other fabrication methods.
