| 摘要: |
| 本文用聚碳硅烷 (PCS) 与煤沥青(P)共混，制得 PCS-P共混物，再经纺丝、氧化、高温烧成，制成了SiC-C纤维。该纤维电阻率随碳含量的增加而减少，强度和模量随碳含量的增高而降低，而且该纤维与环氧树脂复合制得的层合板材，具有良好的吸收电磁波性能。 |

| Abstract: |
| The PCS-P miscellanies have been obtained to blend polycarbosilane (PCS) with coal pitch (P). The SiC-C fibers have been obtained by spinning，preoxidation，heat treatment of these PCS-C miscellanies. The resistivity，strength and modulus of these fibers decrease with the increase of the carbon contents. The composites composed of the SiC-C fibers and epoxy resin have good electromagnetic wave absorption properties. |
