摘要
叙述了复合材料热压罐固化工艺研发试验的制定依据和实施过程要求,重点介绍了复合材料热压罐固化工艺的材料、采样、关键工艺参数和测试项目的选择,对制造过程的下料、铺贴、机加和无损检测要求进行分析,明确了试验方案各关键环节的控制要求,并对复合材料热压罐固化工艺研发试验设计、工艺规范的建立以及对产品质量和形成的工艺规范的适航验证方法进行了阐述。对于工艺规范的适航验证,其工艺的稳定性是验证的重点,可以通过具有代表性的试片级、元件级试验件进行试验。
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.
