Effect of Different Precursor and Carbon Fibre Content on Unidirectional C/C Composites Interlaminar Bonding Strength
C/C composites were prepared by low temperature and hot pressure moulding process from T300 carbon fibre and medium temperature pitch(MTP) or MP with nematic liquid crystalline. The effect of the content of carbon fibre and different proportion of MTP to MP on interlaminar bonding strength (ILBS) of C/C composites was investigated. C/C composites were characterized by ILBS test and scanning electron microscope. Results showed that the ILBS increased with the increase of the content of carbon fibre and proportion of MTP. When the content of carbon fibre was 60.5%, the ILBS of composites prepared from MP reached up to 1.498MPa, and to 3.031MPa from MTP.
