Latest Patents

One of his latest patents is titled "In-situ molding of fiber reinforced composites to net shape." This method involves fabricating composite structures using a single mold to preform a foam core between fiber reinforcement plies. The process includes resin transfer molding to create an integrated foam core composite structure, ensuring mechanical interlock between the foam core and composite skins. The method also allows for the formation of film barriers within the fiber reinforcement plies, enhancing the integrity of the final product.

Another significant patent is the "Method for stabilized cutting of fibrous composite preforms." This innovative technique involves the stabilized cutting of stacked fibrous composite sheets assembled into a preform. By applying a binder to each sheet and utilizing a laser cutting system, the method ensures that the cut ends fuse with the binder, preventing cross-fusing of fibers and maintaining resin permeability. This approach offers a low-cost, highly automated, and repeatable process for producing fiber preforms.
