Abstract

The invention provides a composite material sweeping board, a preparation method and an application of the composite material sweeping board. The sweeping board comprises a panel (1), a core material (2) and a light sandwich material (3), wherein the panel (1) comprises an ultra-high molecular weight polyethylene fiber; the core material (2) comprises a glass fiber, a carbon fiber or a hybrid fiber; the light sandwich material (3) is arranged in the middle of the core material (2) in a clamping manner; the panel (1) is completely coated on the upper surface and the lower surface of the core material (2); and the panel (1), the core material (2) and the light sandwich material (3) are solidified to be an integral structure by the same thermosetting resin. According to the composite material sweeping board provided by the invention, the comprehensive performance, in particular the wear resistance is greatly improved, so that on the basis of keeping the bearing capability, a breakthrough of using the composite material sweeping board to replace steel in light weight and abrasion resistance is achieved, and the composite material sweeping board is especially suitable for bottom plates and side plates of truck boxes, bottom plates of containers and the like; and the composite material sweeping board is simple in preparation method, easy to operate, and suitable for industrial promotion and application.
