摘要
A pultrusion method, equipment for preparing a fiber-reinforced composite, and a fiber-reinforcement composite are provided. The pultrusion method comprises the following steps: i) preforming inner layer fibers; ii) impregnating the preformed inner layer fibers with a first resin to obtain a first preform; iii) heating and curing the first preform to obtain an inner layer profile; iv) preforming outer layer fibers together with the inner layer profile; v) impregnating the outer layer fibers with a second resin to obtain a second preform; and vi) heating and curing the second preform to obtain the fiber-reinforced composite.
