Attempts have been made to reduce weight while guaranteeing and to produce low fuel consumption and environmentally friendly vehicles.
- Carbon fiber is composed of thousands of carbon fiber yarns (filaments) to form a bundle of carbon fibers (fiber bundle, tow).
- the fiber yarn is opened, and the opened carbon fiber yarn is applied in the form of short fiber, long fiber, or continuous fiber.
- the matrix resin can be easily impregnated, the strength of the FRP sheet and the tow prepreg can be improved, and the productivity can be improved.
