Resin Transfer Molding. Molding the resin transfer molding process rtm involves injecting a low viscosity resin into a dry fiber pre form in a closed molding process. Rtm has two primary advantages over resin infusion.
Resin transfer molding rtm uses a liquid thermoset resin to saturate a fiber preform placed in a closed mold. The preform or contoured fiberglass reinforcement is the matrix already in the shape of the. Although the origins of resin transfer molding rtm reach back to post world war ii marine vessel development in the 1950s the process was not applied to aerospace composites until the 1980s.
Once the mold is closed the resin pump pumping both catalyst and resin simultaneously to the mix head then mixes the resin and catalyst together as a.
