Abstract:

In order to overcome shortcoming of the shorter fiber and two-dimensional carbon fabric reinforced perform on low structure strength, this paper designed and prepared the deep crossing linking woven and the curved shallow crossing linking woven carbon fabrics reinforced phenolic resin composits. And the shorter carbon fiber reinforced phenolic resin composites were prepared under the same conditions as the controlled trial. The friction and wear properties of the carbon fiber/phenolic resin (C/PR) composites were tested and the three kinds of worn surfaces were observed. The results showed that: the friction coefficient and the wear rate of the shorter fiber composite was the highest, the curved shallow crossing linking woven C/PR composite has the lowest friction coefficient and the wear rate, and shallow curved cross-linking in the middle. The three dimensional woven structure of layered joint has excellent mechanical and integrity of the composite material and can reduce wear dust adn wear loss of the composite in the friction process, and keeps stable friction coefficient, so that the composite has good frictional properties.
