摘要
热压罐成型工艺是航空航天领域用复合材料构件的重要制备方法之一,工艺过程涉及热和压力在多相材料体系间复杂的相互作用,并影响复合材料成型质量。在物理化学作用机理研究基础上,建立数值模拟方法可有效指导工艺、工装的设计与优化,为先进复合材料研制模式从传统的积木式验证向数字化制造模式转变提供了有力的技术支撑。综述近年先进树脂基复合材料热压罐成型工艺数值模拟方面的主要研究进展,结合国内外研究现状,对热压罐成型工艺数值模拟的发展趋势及亟需解决的问题提出了几点思考。
Autoclave is one of the most important manufacturing processes commonly used to fabricate composite structures with high performances in aeronautical and aerospace area. The autoclave process involves the complex interactions between multiphases and the heat and pressure, which affect the quality of composite materials. The numerical simulation for autoclave process of the composite components based on the physical and chemical mechanism is significant during the design and optimization of the tooling and process, which provides the theoretical support for developing model from the traditional ＂trial and error＂ pattern to the digital manufacturing mode. The main research progress of numericaly simulation of autoclave process has been reviewed in recent years. Combined with the research status at home and abroad, some considerations for the development trends of the autoclave process and urgent problems have been taken in this paper.
