| 摘 要： | 融合韧带网络型泡沫炭与微球型泡沫炭的结构特点,并结合同质复合材料与异质复合材料的互补优点,用填充了纳米AlN的酚醛树脂胶作韧带网络将酚醛树脂微球六角密排,再经过炭化、石墨化处理,成功地制备了纳米AlN/C复合泡沫样品。对该样品进行扫描电镜和X射线衍射测试,结果表明生成的直径在400～500 nm范围的炭纤维和尺寸在150～200 nm之间的纳米AlN颗粒共同增强韧带网络。同时,对纳米AlN增强C/C复合泡沫材料的机理进行了分析解释。

| Abstract: | Merging the structural features of ligamentous reticulated carbon foam and microspheric carbon foam together,and combining the complementary merits b etween homogeneous composite and heterogeneous composite,we prepared nano AlN/C composite foam samples successfully after carbonization and graphitization.In this process,phenol aldehyde resin filled with nano AlN was served as ligament nets,and microspheres were carried on close-packed hexagonal structure.The r esults of the X-ray diffraction and the scanning... |
