HP-RTM

HP-RTM is a high-volume manufacturing process for advanced fiber-reinforced composites. It involves injecting a low-viscosity, fastcuring thermoset resin (like epoxy or polyurethane) into a vacuumsealed mold pre-loaded with fiber preforms (e.g., carbon fiber) at high pressure (typically over 50 bar). The key advantages are extremely short cycle times (often under 5 minutes), high fiber volume content, and low void formation, resulting in high-performance, high-quality structural parts used extensively in the automotive and aerospace industries
