With the continuous improvement of low viscosity, low exotherm, and thermosetting resin system on manufacturing technology, the core material with good diversion performance, the vacuum resin infusion processing is gradually widely used in composite materials production, so as to achieve the desire of improving FRP product quality, maintaining the integrity of its structure, reducing weight, and reducing overall costs becomes possible. This process has been successfully applied to large wind blades and nacelle covers, train head covers, safety helmets, yachts, ship, sports equipment, etc.
Vacuum Infusion processing is a new type of low-cost composite material large-scale forming technology, which eliminates the air of fiber reinforcement materials under vacuum, the use of auxiliary materials can help exhaust excess air, control the resin flow well, achieve impregnation to the fibers and fabrics, so that it can be cured successfully and perfectly.
