Glass fiber reinforced plastic gusset plate for high-speed rails and preparation method

Abstract

The invention relates to the technical field of high-speed rails, and in particular relates to a glass fiber reinforced plastic gusset plate for high-speed rails. The glass fiber reinforced plastic gusset plate comprises a glass fiber reinforced plastic gusset plate body, the glass fiber reinforced plastic gusset plate body comprises a glass fiber reinforced plastic bottom plate and a glass fiber reinforced plastic top, a supporting buffer layer and a reinforcing plate are arranged between the glass fiber reinforced plastic bottom plate and the glass fiber reinforced plastic top, fixed bonding layers are arranged among the glass fiber reinforced plastic bottom plate, the supporting buffer layer, the reinforcing plate and the glass fiber reinforced plastic top, the glass fiber reinforced plastic bottom plate, the supporting buffer layer, the reinforcing plate and the glass fiber reinforced plastic top are fixedly connected through the fixed bonding layers, the supporting buffer layer comprises a supporting elastic frame, the cross section of the supporting elastic frame is in a honeycomb shape, and the supporting elastic frame is filled with sound insulation filling cotton. Through the designed supporting buffer layer and the reinforcing plate, the glass fiber reinforced plastic gusset plate body can be reinforced through the supporting elastic frame of the supporting buffer layer in the using process, noise generated when passengers sit on the glass fiber reinforced plastic gusset plate body is reduced through the sound blocking effect of sound insulation filling cotton, and therefore the using comfort of the high-speed rails is improved.

Description

technical field [0001] The invention relates to the technical field of high-speed rail, in particular to a glass fiber reinforced plastic gusset for high-speed rail and a preparation method thereof. Background technique [0002] FRP is fiber-reinforced plastic, generally refers to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix, glass fiber or its products as reinforced plastics, called glass fiber reinforced plastics, or glass fiber reinforced plastics, Unlike tempered glass. The scientific name of FRP is fiber-reinforced plastic, that is, fiber-reinforced composite plastic. According to the different fibers used, it is divided into glass fiber reinforced composite plastics, carbon fiber reinforced composite plastics, boron fiber reinforced composite plastics, etc. It is a kind of composite material with glass fiber and its products as reinforcing material and synthetic resin as matrix material. Fiber-reinforced composites are composed...

Problems solved by technology

[0005] The object of the present invention is to provide a glass fiber reinforced plastic gusset for high-speed rail and its preparation method, to solve the phenomenon that the collision caused by the above-mentioned background technology leads to the damage of the glass fiber reinforced plastic gusset, which leads to the exposure of the equipment inside the glass fiber reinforced plastic gusset, which affects the performance of the high-speed rail. Running, and when passengers get on and off the high-speed rail, friction will cause the surface of the FRP gusset to wear
