Brief Introduction of RTM Molding Technology   Since the 1990s, advanced industrial countries and regions in Europe and the United States have proposed concepts and technical development directions such as cost-effeetive composites and affordable composites for resin-based composites, and have invested heavily in a series of plans such as ACT (advised composite technology) and ATP

RTM Process and 3D Braided Composite Material Manufacturing Technology   Three-dimensional braided composite materials are formed by weaving dry preforms using textile technology. The dry preforms are used as reinforcements, and resin transfer molding (RTM) or resin film infiltration (RFI) is used for impregnation and curing to directly form a composite material structure. As an

What are the Methods for Preforming RTM Reinforced Materials?   In RTM Molding, the fiber-reinforced material must first be made into a shape similar to the product to be processed before molding. The process of making a preform of the reinforced fiber and its fabric is called preforming, and the preform of the reinforced fiber
