| Abstract: |
| This paper researches on the preparation of friction materials containing carbon fiber composite wastes. Adding the carbon fiber tube waste and carbon fiber woven cloth waste as one of the components respectively, the resin-based friction materials were prepared by a dry hot pressing molding process. The effects of the content of two kinds of wastes on the impact toughness and friction properties of the material were tested, and the morphological characteristics of the friction film on the friction surface were analyzed by SEM. The results show that adding carbon fiber waste can improve the impact strength and reduce the wear rate of the friction material. An appropriate amount of carbon fiber waste can improve the friction stability of the material and is beneficial to promote the formation of the larger friction film block. Adding 6% carbon fiber composite tube waste or 8% carbon fiber woven cloth waste shows advantageous properties. |
