The invention discloses a
pultrusion method for a carbon
fiber and
glass fiber composite board. The
pultrusion method comprises the following steps of (1) unwinding yarns on a creel; 2) threading and
combing yarns; 3) impregnating
carbon fibers in a
steeping vat; 4) pre-curing a carbon
fiber mold, specifically, pre-curing impregnated carbon
fiber yarns through a first
pultrusion mold to form a pre-cured carbon plate; (5) impregnating glass fibers in the
steeping vat; and (6) finally curing a product, specifically, after
glass fiber yarns are impregnated, uniformly distributing the
glass fiber yarns around the pre-cured carbon plate according to the specific number of glass fibers, entering a second pultrusion mold, and curing to obtain a carbon-glass mixed pultrusion plate. According to the method, the pultrusion plate which takes the
carbon fibers as a sandwich layer and the glass fibers as an outer layer and is used for preparing a blade of a
wind power generator can be prepared, the problems that existing
carbon fibers are excessive in performance and high in price, and existing glass fibers are insufficient in performance and heavy in
mass are solved, the carbon fiber
layers in the plate can be neatly arranged in the plate, and the
mechanical property of combining the two fibers is exerted to the greatest extent.
