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 material processing, and relates to a skateboard surface and a preparation method thereof. The skateboard surface is composed of a prepreg layer and a polyurethane layer, wherein the prepreg layer is made of 100 parts glass fiber reinforced thermoplastic resin composite material unidirectional prepreg layer, and the polyurethane layer is 5 to 10 parts in sheet form thermoplastic polyurethane. The skateboard plate obtained by the invention has improved water resistance, and is not prone to warping and delamination after contact with water. The preparation method does not use glue at all, reduces the glue application process, and reduces the pollution in the processing process; in addition, the slideboard made of the glass fiber reinforced thermoplastic composite material has a thinner surface and higher strength.

Description

technical field [0001] The invention belongs to the technical field of composite material processing, and relates to a skateboard surface and a preparation method thereof. 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 purpose is to improve the strength and elasticity of skateboard ...
