Application of Vacuum Infusion Technology in the Production of Wind Turbine Nacelles     Core Tip: "Vacuum Resin Infusion Process" (VRIP), also known as "Vacuum Assisted Resin Diffusion Molding Process" (VARIM), or "Vacuum Assisted Resin Transfer Molding Process" (VARTM). The principle of this process is to inject resin into the prefabricated reinforcement material with the
