Pultrusion method and equipment for preparing a fiber-reinforced composite

The present invention relates to a pultrusion method and equipment for preparing a fiber-reinforced composite. The pultrusion method comprises the following steps: i) preforming inner layer fibers (1); ii) impregnating the preformed inner layer fibers (1) with a first resin to obtain a first preform; iii) heating and curing the first preform to obtain an inner layer profile (5); iv) preforming outer layer fibers (6) together with the inner layer profile (5); v) impregnating the outer layer fibers (6) with a second resin to obtain a second preform; and vi) heating and curing the second preform to obtain the fiber-reinforced composite. By arranging a curing step between the two impregnating steps, the method of the present invention can realize stepwise curing of the fiber-reinforced composite. With this method, a thicker fiber-reinforced composite and a fiber-reinforced composite which requires impregnation with two resins can be efficiently obtained, thereby intermingling of inner and outer layer resins and infiltration of the inner layer resin into the outer layer can be avoided.
