Forming method of light high-protection PE bulletproof helmet

The invention discloses a forming method of a light-weight high-protection PE bulletproof helmet. The method comprises the steps that 1, lofting design and tailoring are conducted; 2, preparing a helmet shell laying body; 3, preheating and forming; 4, hot press molding; 5, hot-pressing, cooling and molding; 6, trimming and punching; vII, adhering an edge sealing adhesive tape; 8, inner and outer surface treatment; 9, spraying polyurea; and 10, assembling a suspension system and a cap sleeve. The biorthogonal PEUD prepreg and the PE plain prepreg fabric are adopted as the helmet shell main body structure and the appearance cloth respectively, the bending strength and the inward deformation resistance of the helmet shell are improved, the blunt trauma possibility is reduced, the shape and the laying mode of each surface layer in the helmet shell laying body are combined for design, and the manufacturing cost of the helmet shell is reduced. The lateral rigidity and the top rigidity of the helmet shell are greatl
