Thermoset Carbon Fiber Prepreg is an intermediate material in the form of a sheet of carbon fiber impregnated with thermoset matrix resin. There are various types of prepreg such as UD prepreg (unidirectional prepreg), in which carbon fibers are aligned in one direction, and cloth prepreg, in which carbon fibers are woven into a fabric and impregnated with matrix resin.
