Study on the Orientation of Unidirectional C/C Composites

This present investigation describes the orientation and its influence factors of unidirectional C/C composites prepared by PAN-based carbon fiber and mesophase pitch (AR-MP) through hot pressure molding process. And the orientation of C/C composites was analyzed by POM and XRD. The experimental results indicated that the AR-MP dispersed in carbon fiber had a strong flow texture, showed a matrix preferentially oriented parallel to fiber surface. Under the pressure of 25MPa, the orientation of composites was better than under 50MPa. Moreover, the sample orientation varies in the two directions both perpendicular to the direction of carbon fiber. Better orientation was obtained in the testing direction which was perpendicular to the direction of carbon fiber and molding pressure.
