国产复合材料预浸料过程控制的认识与实践

Realization and practice of process control for domestic composite prepreg

材料满足适航要求是其应用于民用飞机的前提,材料供应商需要按照适航的基本原则,建立过程控制体系,保证材料的质量稳定性和一致性。结合中航复合材料有限责任公司在国产预浸料过程控制体系建立中所开展的工作,从人、机、料、法、环、测六个质量控制要素阐释了国产预浸料"过程控制"的技术内涵和具体实施工作的路径。国产预浸料过程控制文件(Process Control Documents,以下简称PCD)的实施提高了产品合格率、产品质量稳定性和一致性、生产效率并降低了成本,其所带来的显著经济效益将会推动过程控制体系在国内航空复合材料供应商中的推广普及,带动航空复合材料制造产业链整体水平的提升,为航空复合材料的持续发展提供动力。

That materials satisfy the airworthiness requirements is the premise of their application on civil aircraft.material suppliers have to establish process control system according to the fundamental principles of airworthiness to ensure quality stability and consistency of materials. Combined with the work carried out by AVIC Composites Co.Ltd during the establishment of process control system for domestic composite prepreg, this article expounds the technical connotation and approach of process control for domestic composite prepreg from the six quality control elements including man, machine, material, method, environment and measurement.The implementation of process control documents(PCD) raised product qualification ratio, product quality stability and consistency and production efficiency, also reduced product costs. The remarkable economic benefits brought about by PCD will promote the spread and popularization of process control system among domestic aerial composite suppliers, willdrive the elevation of the overall level of the aerial composite manufacture industrial chain and will provide power for sustained development of aerial composites.
