In this paper, the fabrication method and mechanical and wear properties of Carbon/Carbon composites from Bacterial Cellulose (BC) Form/Polymer composites is investigated. The effects of material properties and configurations on the properties of BC composites were discussed, and three dimensional micro structure for strengthening in BC composite was also considered. A fabrication method of Carbon/Carbon composites with BC form, in which BC microfibril network of three dimensional structure of nano-scale and their bonding conditions remain, was developed. The experimental results of wear characteristics were shown for the nano-Carbon/Carbon composites from BC. Wear tests of the composites were conducted under dry sliding condition. The coefficient of wear took the low values of 0.17-0.18 during the tests. It reveals that the composites have excellent wear property in comparison with silicon nitride ceramics and the diamond-like carbon (DLC).
