NOVELTY - The utility model claims a straw graphene urban rail composition brake shoe, comprising a steel plate and sticking friction brick of the steel plate, the steel plate is an arc plate; two ends of the arc-shaped plate is tooth-shaped; the arc-shaped plate is provided along the radial direction of arc convex, arc-shaped bulge two sides are respectively pasted with one of said friction block, two friction blocks are provided with radiating grooves, two ends of the arc-shaped bump is provided with a connecting hole; the friction block is a straw-modified graphene friction block. This utility model of train brake at elevated temperature, stable resistance, impact strength, wear resistance, acid resistance and alkali resistance, the utility model friction block main material is wheat extract, agricultural waste recycling, reduces environment pollution, each performance index is beyond the traditional technique and method for production of the brake, and the processing cost is low, the price is low.
