New environmental protection sisal fiber brake pads developed successfully
"Environmentally-friendly sisal fiber reinforced automobile brake pads" was successfully developed at Xi'an Jiaotong University. After the authoritative department performance test, the friction coefficient, wear rate, hardness, impact toughness and other properties of the brake pads all reached the national standard. At the recent results appraisal meeting held in Zhanjiang City, Guangdong Province, the experts all agreed that: This type of eco-friendly automotive brake pad product with sisal as reinforcing fiber is a domestic initiative. It has the advantages of stable friction coefficient, good heat recovery performance, low brake noise, long service life, and low cost. At the same time in the production and use of the process to eliminate the harm to the human body and the pollution of the environment, creating a new era of China's automotive brake pads. And for our traditional sisal industry opened up a new direction of application.
The project was jointly developed by Xi'an Jiaotong University and Guangdong Eastern Sisal Group Co., Ltd. Prof. Cheng Guangxu of the Xi'an Jiaotong University, the project team leader, said: Since the 1970s, researchers and automakers around the world have been looking for substitutes for asbestos fibers. The main reinforcing fibers in brake pads are steel fiber and carbon fiber. Glass fiber, aramid fiber and other organic synthetic fibers are the main products. However, there are some weaknesses in using a single fiber as a reinforcing material. Therefore, several types of fiber-reinforced friction materials are currently used. Sisal fiber is a renewable resource and can be naturally degraded. The decomposition product is non-toxic and harmless, and its friction properties are excellent. After several years of research, researchers have overcome the key technical problems of sisal fiber used in automotive brake materials during product development and research, and successfully developed automotive brake materials that are simply reinforced with sisal fibers. It is also an innovation in the field of friction-reinforced fiber research. The prospect of environmentally friendly sisal and brake pads is promising, and it can be applied to the field of friction braking in the machinery industry.
