Latest Patents

Roger G Ghanem holds a patent for "Manufacturing control systems and logic for prognosis of defects in composite materials." This patent presents advanced manufacturing control systems designed for composite-material structures. The methods outlined include techniques for assembling and operating these systems, as well as transfer molding techniques aimed at predicting and ameliorating void conditions in fiber-reinforced polymer panels. The patented method involves receiving a start signal indicating that a fiber-based preform is inside a mold cavity. It also includes transmitting a command signal to inject pressurized resin into the mold, which induces resin flow and impregnates the fiber-based preform. An electronic controller is utilized to receive signals from a distributed array of sensors attached to the mold, which monitor pressure and temperature at various locations within the mold cavity. The controller then determines measurement deviations from calibrated baseline values. If any measurement deviation exceeds a calibrated threshold, a void signal is generated to indicate a detected void condition.
