Film boiling chemical vapor infiltration (FB-CVI) is considered as one of the fastest process methodologies for manufacturing carbon-carbon (C–C) composite products and possesses various advantages compared to conventional methodologies. However, there are safety concerns associated with this process for large-scale manufacturing, mainly owing to the intrinsic nature of the precursor and the process conditions. Considering the multifunctional interactions of the various systems during the process, a system-theoretic process analysis (STPA)/system theoretic accident model and process (STAMP) model is used to perform a safety analysis of the hazardous states of the FB-CVI process at the system level. As a case study, the FB-CVI process equipment employed for the manufacturing of C–C composites is considered. The safety constraints present in the system are assessed for adequacy through a hazard analysis by STPA/STAMP. The analysis through STPA/STAMP demonstrated the capability to create proactive strategies for the design and realization of process equipment that can be employed to manufacture C–C composite products through the FB-CVI process.

膜沸腾化学气相渗透（FB-CVI）被认为是制造碳-碳（CC）复合产品的最快工艺方法之一，与传统方法相比具有各种优势。然而，主要由于前体的固有性质和工艺条件，与用于大规模生产的该工艺相关的安全性问题。考虑到过程中各个系统的多功能交互作用，使用系统理论过程分析（STPA）/系统理论事故模型和过程（STAMP）模型对FB-CVI过程的危险状态进行安全分析。系统级别。作为案例研究，考虑了用于制造C–C复合材料的FB-CVI工艺设备。STPA / STAMP通过危害分析评估系统中存在的安全约束条件是否足够。通过STPA / STAMP进行的分析表明，可以创建主动策略来设计和实现可通过FB-CVI工艺制造C–C复合产品的工艺设备。
