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 根据热解碳中间相、 cvi - pip系sic基体相的组织构成与外貌特征,通过对热解碳中间相、 cvi - pip系sic基体相的生长过程和生长特征进行分析,提出了基于层生长模式的致密化过程理论,解释了热解碳中间相、 cvi - pip系sic基体相以及钉扎诱导结构多重界面的形成: ( 1 )在1150下, cvi - sic亚基体相遵从“过饱和?凝聚?融合”机理沉积,以8f型? sic为主,同时还会有少量4h型? sic ,无游离si和游离c存在; ( 2 ) pip - sic亚基体相由非晶态sic以及弥散分布的- sic微晶、 si - o - c和游离c组成; ( 3 )热解碳中间相与碳纤维增强相之间、 cvi - sic亚基体相之间形成渗透钉扎结构过渡界面, pip - sic亚基体相与摘要cvi一sic亚基体相之间形成诱导结构过渡界面。
Polarization microscope had observed that the size of sphere crystal of pp after adding organic rigid particles became smaller , the excellent compatibility of interphase between matrix and organic rigid particles in composite has been proved , and the organic rigid particles were drew out into cavities from matrix in the photograph of the impact breaking section by sem . the reason of enhanced toughness of the composite is that the material absorbed amount of energy at forming cavities , which is the mechanism of the pp composite toughened with the organic rigid particles 偏光显微镜显示加入有机刚性粒子可使pp的球晶尺寸减小, sem观察到复合材料中基体材料和刚性粒子的界面相容性较好,在冲击破坏的材料断面上,刚性粒子明显被拔出形成“空穴” ,这些微小空穴较易产生而吸收能量,从而提高了材料的断裂韧性,这是刚性粒子复合聚丙烯的增韧机理。
