Problems solved by technology

There are also some products that use the top-layer glass fiber reinforcement technology to greatly increase the toughness and strength of the board surface. However, in the design and lay-up process of the skateboard surface, since the top layer is laid with glass fiber, this design has no effect on the bottom of the board surface that is prone to fracture. Doing good enhancements is a design flaw

Abstract

The invention belongs to the technical field of composite processing, and relates to a natural fiber-reinforced thermoplastic composite material prepreg tape, and a preparation method thereof. The method comprises the following steps of (a) cutting the natural fiber-reinforced thermoplastic composite material prepreg tape and laying; (b) heating the prepreg tape layer into an infrared-ray oven and melting; (c) putting the melted layer into a cold press machine to carry out cold press and cooling to obtain a sheet material; and (d) after the cooling process is finished, cutting the obtained sheet material, punching, polishing, cleaning burs, carrying out precision grinding, spraying paint and applying a surface to obtain a skateboard surface. The prepared natural fiber / thermoplastic resin skateboard surface can be stored for a long time, and after hot press, the natural fibers can be impregnated by the resin thoroughly, so that the material particularly the natural fibers can be kept dry. The natural fibers are not liable to mildew or deteriorate. Products adopted by the invention have no harm to a human body and do not produce adverse reaction.

Description

technical field [0001] The invention belongs to the technical field of composite material processing, and relates to a preparation method of a natural fiber-reinforced thermoplastic composite material prepreg tape skateboard surface. Background technique [0002] Commercially available skateboards are mainly made of wooden materials. The advantages of Canadian maple wood mainly lie in the hard texture of the material, compact wood, good polishing, and moderate strength. The skateboard surface processed with this wood has good elasticity and high strength. However, skaters require lighter, thinner, and stronger boards, and if improvements are still made on the basis of existing materials, it will lead to weakening of the strength and elasticity of skateboards, so many merchants turn their attention to alternatives to wood. on the material. [0003] At present, many brands produce fiber optic decks. The so-called fiber optic decks are reinforced with glass fibers. The main pu...
