Ceramic brake block

Abstract

The invention discloses a ceramic brake block, which consists of the following ingredients in the following parts: 20 to 30 parts of alumina silicate fiber, 30 to 50 parts of glass fiber, 40 to 50 parts of carbon fiber, 30 to 35 parts of bamboo charcoal fiber, 50 to 80 parts of ceramic fiber, 20 to 25 parts of asbestos fiber, 30 to 40 parts of polyester fiber, 40 to 45 parts of polyacrylonitrile fiber, 20 to 25 parts of polyvinyl alcohol fiber, 10 to 15 parts of polypropylene fiber, 15 to 25 parts of ultra to high molecular weight polyethylene fiber, 10 to 15 parts of sepiolite fiber, 20 to 25 parts of fibrilia, 15 to 18 parts of viscose, 5 to 10 parts of hollow particles, 4 to 6 parts of glass particles, 5 to 7 parts of silicon carbide, 5 to 8 parts of aluminium carbide, 2 to 5 parts of silicon dioxide, 2 to 5 parts of magnesium oxide, 3 to 6 parts of graphite, 10 to 12 parts of frictionpowder, 10 to 12 parts of reclaimed rubber, 8 to 10 parts of silicon carbide whiskers, 8 to 10 parts of magnesium borate whiskers and 6 to 8 parts of vanadium pentoxide. The ceramic brake block provided by the invention has the advantage that through the ingredient improvement matching and the composition, the technical problems of easy rustiness, higher noise, unstable high-temperature friction performance, easy locking or dragging friction, lower abrasion resistance performance and the like in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of mechanical brake material technology, in particular to a ceramic brake pad with good braking effect and safety. Background technique [0002] The braking system is one of the most important safety systems on a car, and the brake pads are an important part of the entire braking system. Conventional brake pads are divided into: 1. Asbestos type, because asbestos fibers have the characteristics of high strength and high temperature resistance , so it meets the requirements of brake pads and clutch discs, and at the same time has the tensile strength of fibers and the hardness and wear resistance of advanced metal materials; Mixture, the main advantage is that it can adapt to normal work at higher temperatures; 3, asbestos-free organic type, mainly uses glass fiber, aromatic polyester fiber and other fibers as reinforcement materials, and its performance mainly depends on the type of fiber and other mixture....
