英文摘要	系统研究了含钴聚碳硅烷交联丝的氧含量对所成含钴碳化硅(CO-SIC)纤维结构与性能的影响。研究结果显示,较之交联丝CO-PCS-AIr,CO-PCS-O2的氧含量较高,陶瓷产率较高,所成纤维的SICXOy相含量较高、β-SIC和COSI晶粒的增长速度较快,晶粒的尺寸较大,达到最大力学性能的烧结温度较低,电阻率也较低。该纤维电阻率在100~103Ω·CM之间可调,且具有一定的磁性,有望用作吸波纤维。; In this work,it was systematically studied that how oxygen content of cured cobalt-containing polycarbosilance(PCS) fibers influences the structure and properties of cobalt-containing silicon carbide(Co-Si C) fibers.Compared to cured Co-PCS-air fibers,Co-PCS-O2 fibers have a higher oxygen content and higher ceramic yield.For Co-PCS-O2 fibers derived from cured Co-PCS-O2,lower pyrolysis temperature was required to reach maximum mechanical properties.And higher Si CxOycontent,higher growing speed and final sizes of β-Si C and Co Si grains and lower electrical conductivity were observed.Co-PCS-O2 fibers have a electrical conductivity controllable between 100-103Ω·cm and were magnetic to some degree,enabling this kind of fibers to have the potential to be used as wave-absorbing materials.; 国家自然科学基金面上资助项目(51002127;51072169)
