摘要

In this paper, carbon cloth woven in twill structure was adopted and a new kind of treatment method was used for carbon cloth, which is called carbon powder surface treatment. The detail method of carbon powder treatment is stated as following: phenol was dissolved in alcohol liquid and made into solution firstly, and then put the carbon cloth in the solution and let it soak, after that, the carbon cloth was taken out from the solution and put in an oven at a high temperature. The process above made phenol carbonized on carbon cloth. As a result, the surface morphology is slightly changed and in this way the bonding between the carbon fiber and the matrix was expected to be improved. Tensile test as well as bending test was conducted and the mechanical properties, such as tensile property and bending property were analyzed and discussed in this research. After that, observation on fracture section by scanning electronic microscope (SEM) and Dynamic mechanical analysis were also conducted in order to understand the fracture mechanism better.
