CBZ molds many automotive parts using VaRTM. We have a proven track record of high strength and excellent surface quality. Features of Infusion (VaRTM) Molding: - No need for large equipment such as autoclaves (pressure vessels) - Easy to mold large structures as a single piece - Minimal volatilization of organic solvents, resulting in a better working environment - Compared to hand lay-up methods, it allows for higher fiber content and lower void content, enabling the molding of high-quality FRP [Features of CBZ] - High adhesion to carbon fibers sized for epoxy resins - High adhesion to glass, aramid, and basalt fibers - Provision of CFRP with excellent bending, compression, and interlaminar shear strength - Low water absorption - Resistance to moisture, oil, and gasoline *For more details, please refer to the PDF materials or feel free to contact us.

Conventional CFRP products are molded using an autoclave, resulting in products with exceptional strength. However, this method requires time for the curing of thermosetting resins under high temperature and pressure, which poses challenges to productivity and has been a factor limiting CFRP products to high-value items. The size of the autoclave, being a pressure vessel, determines the size of the molded products, leading to significant constraints in terms of product size. Thus, the method using an autoclave is unsuitable for mass production of widely used items and has limitations on product size and shape. To overcome these challenges, the RTM (Resin Transfer Molding) method has gained popularity in recent years. The VaRTM method is a type of RTM, where materials are layered, then vacuumed, and thermosetting resin is infused and cured with heat. Since it does not use prepreg, it leads to cost reduction. It is being adopted for wind turbine blades and minesweepers, and it is expected to increase further in the future. Other resins suitable for RTM (VaRTM) can also be introduced.
