AI Technical Summary
Existing liquid molding technologies for composite materials suffer from problems such as difficulty in completely eliminating air bubbles, insufficient fiber impregnation, extremely high dependence on vacuum, and narrow process windows, leading to pore defects, decreased mechanical properties, and low production efficiency.
By introducing ultrasonic vibrations of specific frequency and power, the resin is promoted to impregnate the fibers during the curing process, and microbubbles are actively driven to migrate and be discharged to the exhaust path. Combined with a vacuum system, the molding process is optimized.
It significantly reduces the porosity of composite parts, improves wetting quality and molding efficiency, enhances process stability, broadens the process window, and improves mechanical properties and production efficiency.
