Silicon carbide(SiC)fibrous mats were synthesized by polymer-derived ceramic process and electrospinning technique.Polycarbosilane was used as precursors,which was first electrospun into polymeric fibrous mats followed by pyrolysis at >1 000℃.The crystalline SiC fibrous mats were obtained at 1 200℃.The structural observations reveal that the mats exhibit a 3-dimensional structure with the fiber diameter of 1.1mm.The chemical compositions of the ceramic fibrous mats measured by EPMA are Si,C and a small quan...
1 IntroductionSilicon carbide(SiC)is a promising material formany applications due to its excellent thermal-me-chanical properties and wide band gap semicon-ducting behavior.[1]SiC fibers have been widelyused as reinforcements for composite materials,[2--
