1. an optimized cvi-pip process has been achieved, by which the c / sic composites with 2.1 ig / cm3 high density and uniformity are fabricated in 200 hours . the microstructure and composition of pyrolytic carbon interphase and cvi-pip silicon carbide matrix in the c / sic composites are investigated with the help of polarization microscope, scanning electron microscope, and x-ray diffraction technique, etc . the structure characteristic of pyrolytic carbon interphase and cvi-pip silicon carbide matrix, and effects of cvi-pip process on it are summarized and discussed . by growth course and feature of pyrolytic carbon interphase and cvi-pip silicon carbide matrix analyzed, a whole-course densification mechanism of lamellar-growth-pattern is proposed to explain the densification phenomenon, which makes a systematic understanding on the feature of pyrolytic carbon interphase and cvi-pip silicon carbide matrix, and the multiple stitching interface binding
   根據(jù)熱解碳中間相、cvi-pip系sic基體相的組織構(gòu)成與外貌特征，通過對熱解碳中間相、cvi-pip系sic基體相的生長過程和生長特征進行分析，提出了基于層生長模式的致密化過程理論，解釋了熱解碳中間相、cvi-pip系sic基體相以及釘扎誘導(dǎo)結(jié)構(gòu)多重界面的形成：(1)在1150下，cvi-sic亞基體相遵從“過飽和?凝聚?融合”機理沉積，以8f型?sic為主，同時還會有少量4h型?sic，無游離si和游離c存在；(2)pip-sic亞基體相由非晶態(tài)sic以及彌散分布的-sic微晶、si-o-c和游離c組成；(3)熱解碳中間相與碳纖維增強相之間、cvi-sic亞基體相之間形成滲透釘扎結(jié)構(gòu)過渡界面，pip-sic亞基體相與摘要cvi一sic亞基體相之間形成誘導(dǎo)結(jié)構(gòu)過渡界面。
