Abstract

The invention provides a glass reinforced plastic and a glass reinforced plastic swallow tail made of the glass reinforced plastic. The glass reinforced plastic is prepared from epoxy resin, carbon fiber, glass fiber, basalt fiber, metal powder, a plasticizer, a curing agent, a flame retardant, a tackifier and a filler. Through reasonable proportioning of the specific raw materials, the tensile strength of the glass reinforced plastic can be increased to be 550 to 600 MPa from 370 to 500 MPa at present, so that the bending parts of the swallow tail made of the glass reinforced plastic are effectively prevented from being cracked, and the safety of the swallow tail in the braking process is guaranteed; the glass reinforced plastic swallow tail provided by the invention also has excellent corrosion resistance and high-temperature resistance, so that the surface treatment working procedure of the swallow tail can be cancelled in the actual production of brake linings, the production efficiency can be improved, the application environment of the brake linings can also be broadened, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of railway transportation equipment, and in particular relates to a glass fiber reinforced plastic and a glass fiber reinforced plastic dovetail made therefrom. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, rail transit has gradually developed into my country's important infrastructure, the main artery of the national economy and the preferred tool for people to travel. The development of modernization has made my country's railway industry develop by leaps and bounds. [0003] In the actual operation of urban rail vehicles, a good and stable braking system is the guarantee for their safe operation. Due to the continuous improvement of the running speed of urban rail vehicles, the braking load of the train is greatly increased, which also puts forward higher requirements for the braking system of the train. The brake pad ...
