1·Spinnable mesophase pitch was prepared from catalytic cracking residue of petroleum and uniform mesophase pitch carbon fibre (MPPCF) was obtained.

以石油系催化裂化渣油为原料，调制出可纺性的中间相沥青，并纺出均匀的中间相沥青纤维。

2·When the content of PEA is less than 10%, the blends are well-spinnable, and the composite fibers have a well-developed highly oriented fibrillar structure along the fiber axis.

且PEA含量低于10％时，共混物的可纺性好，复合纤维在流动方向形成明显的取向微纤；
