摘　　要：研究了采用化学气相沉积(CVD)和树脂浸渍/固化/碳化相结合的致密工艺制备的大型整体毡炭/炭复合材料的密度、开孔率及压缩强度的分布状况,分析了致密化工艺中存在的可能造成这种分布现象的因素并讨论了密度分布可能带来的影响。The density and open porosity as well as compressive strength distribution of large-size integral felt reinforced C/C composites made by the combination compact process by chemical vapor deposition (CVD) and resin impregnation/curing/carbonization is investigated.Some possible factors that have caused this phenomenon during the process of densification are analysed.Furthermore,the main effects and effect derived from this kind of distribution of density on the composites are discussed.
