连续同步复合法是一种建立在传统CVI原理基础上的制备碳布增韧陶瓷基复合材料的新工艺，在制备过程中碳布通过连续缠绕在旋转的石墨衬底上，使纤维预制体的制备与基体的热解沉积同步进行，从而实现增韧相与基体在宏观和微观尺度上同步复合。通过控制反应物气体浓度、沉积温度与碳布缠绕线速度，达到控制微观孔隙网络与宏观孔隙的协调致密化。采用连续同步复合法制备碳布增韧SiC基复合材料，实际密度可达其理论密度的93%，制备周期显著缩短。

旋转CVI是在CVI原理基础上发展的一种制备C/SiC复合材料的新工艺，通过石墨衬底的旋转，使预制体的制备与基体的沉积同步进行，能有效消除一般CVI工艺过程中存在的“瓶颈”效应。在自制的旋转CVI设备上实验，探索了旋转CVI工艺参数中CH3SiC13h（MTS）的流量与浓度、沉积温度和C布缠绕线速度对SiC基体沉积速度，以及沉积温度对基体结构的影响。并在低压（5kPa）、高温（1100℃）、400mL•min-1H2、200ML•min-1Ar、MTS40℃与C布以1.1-3.5mm-minll的线速度连续旋转的沉积条件下，实现了单丝纤维间微观孔隙、纤维束之间以及C布层间宏观孔隙的致密化同步完成。

为缩短CVI法制备C/SiC复合材料的工艺周期并降低成本，研究了CVI工艺过程中沉积温度、MTS（CH3SiC13）摩尔分数和气体流量对SiC沉积速率和MTS有效利用率的影响。实验结果表明：提高沉积温度，常压下1100℃时增大MTS摩尔分数（11%→19%），都有利于提高SiC沉积速率;提高沉积温度和降低反应物气体流量，能提高MTS有效利用率。在优化的工艺条件下，预制体的微观孔隙内沉积了致密的SiC基体，沉积速率达到142μm/h左右，并有效消除了基体中裂纹的形成.MTS的有效利用率为11%～27%。

The continuous synchronous composite (CSC) process is a new technique, the preparation of reinforcement-phase accompanied simultaneously the deposition of SiC matrix, based on CVI principles for fabrication of ceramic matrix composites. In the CSC process, there was a gradient temperature field on the surface of the graphitic substrate, consisting of high (1000-1200℃), intermediate (900-1000℃) and low (700-900℃) temperature regions, by a bottom heating-element. Following the rotating substrate, micro-pores were well infiltrated in the intermediate temperature regions by gas diffusion transport, and macro-pores were rapidly filled with SiC in the high temperature regions by gas flow transport, respectively. In the present paper, 2-dimension carbon cloth reinforced SiC composites was fabricated by CSC process, and the microstructure, deposition rate and conversion efficiency of methyltrichlorosilane (MTS) were investigated. The densification of C/SiC composites was uniform, and the highest deposition rate within macro-pores was 25μm h−1, and the conversion efficiency of MTS varied from 11% to a maximum of 27%.
