Resin Infusion

Resin infusion is a method used in composite manufacturing to impregnate dry reinforcement materials, like fibers or fabrics, with a liquid resin. This process involves placing the dry reinforcement in a mold and then introducing the resin under vacuum pressure, allowing it to permeate the reinforcement thoroughly. The vacuum facilitates the removal of air pockets and ensures uniform resin distribution, resulting in a high-strength composite with consistent properties. Resin infusion offers advantages in creating complex shapes, minimizing waste, and producing lightweight yet durable structures.
