通过纤维预成型体的化学气相渗透（CVI）制备的碳/碳复合材料的碳基质的拉伸性能从室温至2200°C测定。使用了微复合材料试样。为此，通过基于化学气相沉积的技术在低模量碳纤维上沉积碳涂层。从单丝增强微复合材料获得的应力-应变曲线推导出碳基体的力学行为。这与用X射线衍射法表征的纳米结构特征有关。的趋势进行了讨论，相对于那些证明在以前的论文中的碳纤维。
Tensile properties of carbon matrices for carbon/carbon composites made via chemical vapor infiltration (CVI) of a fiber preform, were determined from room temperature to 2200°C. Microcomposite test specimens were used. For this purpose, a carbon coating was deposited on low modulus carbon fibers via chemical vapor deposition based techniques. The mechanical behavior of the carbon matrix was derived from the stress–strain curves obtained with the single filament reinforced microcomposites. It was related to features of nanostructure characterized using X-ray diffractometry. The trends are discussed with respect to those evidenced on carbon fibers in a previous paper.
