摘要：

The microstructure and properties of uni-directional pitch-based carbon-carbon composites are explained in terms of the chemical composition of pitch precursors, Pitches are characterized by standard procedures (elemental analysis, softening point and solubility tests), extrography which is a simple and rapid silica gel adsorption chromatographic technique, Fourier transform infra-red and gas chromatography of the toluene-soluble fraction. Pitch pyrolysis behaviour is monitored by hot-stage microscopy. The main microstructural features of uni-directional composites from pitches and commercial PAN-based carbon fibres are determined by light microscopy and scanning electron microscopy.
