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. |
