前言碳—碳复合材料具有独特的性能,在航天工业中由于它能在高温下耐烧蚀,并具有优异的强度,因此可用作隔热材料。生产这些碳一碳复合材料的最一般方法是将碳的化学蒸汽沉积(CVD)在一种纤维上,即碳毡基体上。本研究的目的是用热的煤焦油沥青浸渍碳 Preface Carbon-carbon composites have unique properties that can be used as insulation materials in aerospace applications due to their ability to resist ablation at high temperatures and excellent strength. The most common way to produce these carbon-carbon composites is by chemical vapor deposition (CVD) of carbon on a fiber, ie, a carbon felt matrix. The purpose of this study is to impregnate carbon with hot coal tar pitch
