The lower HDPP plate 1 is fixedly bonded with a carbon fiber plate 3 through an adhesive. Both ends of the carbon fiber plate 3 are fixedly bonded with glass fiber plates 2 through an adhesive. The upper and lower outer surfaces of the carbon fiber plate 3 and the glass fiber plates 2 are all on the same horizontal plane, that is, the carbon fiber plate 3 and the glass fiber plates 2 have the same thickness. In actual use, the thicknesses of both the carbon fiber plate 3 and the glass fiber plates 2 are 0.12 mm;

[0021] Among them, the glass fiber plate 2 is a medium-density glass fiber plate. The carbon fiber plate 3 is composed of unidirectionally vertically woven carbon fiber filaments.

[0024] Above the carbon fiber board 3 and the glass fiber board 2, an upper HDPP board 4 is fixedly bonded through an adhesive. Among them, both the lower HDPP board 1 and the upper HDPP board 4 are made of high-density polypropylene material, which is a high-density, side-chain-free, highly crystalline linear polymer with excellent comprehensive properties.
