This paper describes the formulated basis and the implementary requirements for a composite autoclave curing process research plan, emphasis on the selecting of the materials, sampling, critical process parameter and testing items. This paper also specifies the critical control requirements for the cutting, plying, machining and non-destructive testing requirements during the fabrication and analyzes the influence of above factors on the quality of final composite parts, meanwhile introduces the experimental design for the composites autoclave curing process and the establishment  of process specification. Finally, the paper introduces the product quality-keeping method and airworthiness verification method for composite parts fabrication process. For the airworthiness verification of composite process specifications, the stability of the process is the key point, which can be tested by using representative test panel and components.
