A glass fiber net reinforced bamboo fiber molded slide plate and its preparation method

Abstract

The invention provides a glass fiber web reinforced bamboo fiber mould pressing sliding plate, which is made of bamboo veneers and prepreg arranged between the two layers of bamboo veneers, and the invention also provides a preparation method, which comprises the following steps of: sorting bamboo fibers, sequentially and crossly paving a glass fiber net and the bamboo fibers from bottom to top toobtain a preformed body, impregnating an adhesive, covering the surface of the preformed body with an epoxy resin adhesive film to obtain the prepreg, assembling the bamboo veneers and the prepreg and carrying out hot pressing molding to obtain the sliding plate. According to the invention, the assembly is simple and convenient; in the hot pressing molding process, after the epoxy resin adhesivefilm on the surface layer of the prepreg is heated, the epoxy resin adhesive can be adhered to the bamboo veneers, so that the bonding strength of the sliding plate is increased; after the hot pressing molding, the epoxy resin adhesive film has elasticity, and the sliding plate is good in shock resistance and fracture resistance; the prepreg is formed by overlapping glass fiber nets and bamboo fibers layer by layer, so that the longitudinal performance and transverse performance of the sliding plate are good; and the prepared sliding plate is light.

Description

technical field [0001] The invention belongs to the technical field of bamboo fiber composite materials, and in particular relates to a glass fiber net reinforced bamboo fiber molded slide plate and a preparation method thereof. Background technique [0002] Canadian maple has good elasticity, moderate hardness, strong stability, not easy to deform, wear-resistant, corrosion-resistant, shock-absorbing, sound-absorbing and other excellent properties, so it is recognized as the best tree species for making skateboards. However, the growth period of Canadian maple is 50-70 years, and the price is relatively expensive, and the strength and elasticity of the skateboard made of cheap birch are lower than that of maple. [0003] With the development of science and technology and the increasing shortage of wood resources, the skateboard with bamboo as the main material has gradually become the mainstream. After years of development, bamboo has gradually become a It has become one o...

AI Technical Summary

Problems solved by technology

However, due to the uneven appearance of the skateboard and the diversification of the appearance design, the processing technology is complicated, and most of the bamboo skateboards are assembled in the same direction along the grain, the structure is simple, the mechanical properties in the length direction are good, and the longitudinal bending strength is 80MPa~ 95MPa, the mechanical properties in the width direction are poor, the transverse bending strength is 20MPa~40MPa, the bonding performance of the glass fiber mesh reinforced slide plate is poor, and the interlayer bonding performance is poor
