Introduction and guidance on vacuum impregnation molding technology for FRP structures.
Regarding vacuum impregnation molding technology, it is quicker and cheaper to ask engineers directly than to search for practical textbooks or literature.
Vacuum infusion molding technology is a technique developed and put into practical use in Europe and the United States to dramatically improve the molding method of FRP yachts and boats that were traditionally hand-laid. Various attempts were made during the technology development process, each given a name, but the VaRTM (Vacuum assisted Resin Transfer Molding) technology is one of the most representative. The characteristic of this molding method is that after layering dry reinforcing fiber cloth in a mold, it is covered with a transparent film and sealed around the edges for preparation. Then, the layered part is placed under vacuum, and liquid resin is supplied from one end to impregnate the reinforcing cloth, which is then cured. Compared to traditional hand-laying methods, this process significantly shortens the resin impregnation phase, which is crucial for the quality formation of FRP. It can theoretically impregnate all voids with resin and visualize the impregnation process, ensuring high quality.
