以高温煤焦油沥青为原料，研制出优质煤系可纺中间相沥青，并纺出中间相沥青纤维。经预氧化、炭化和石墨化后，获得了超高模量石墨纤维。
Using high-temperature coal tar pitch as raw material, a high quality coal-based spin-on mesophase pitch was developed and a mesophase pitch fiber was spun out. After pre-oxidation, carbonization and graphitization, ultra-high modulus graphite fibers were obtained.
