结合航空制造行业的重大实际需求，研究飞机大型复杂复材零件热压罐成型的工装设计难点，提出基于各向热膨胀系数匹配的复材工装模板铺层设计方法，选择合适的复材制作工装模板，通过对工装模板铺层设计实现工装与制件各向热膨胀系数相匹配。提出基于应力临界点温度的工装模板型面精确设计方法，分析碳纤维增强树脂基复材固化工艺曲线，以内应力为零的临界点温度时的工装型面作为零件型面，据此求解工装模板型面，克服了传统方法由零件常温型面直接拷贝生成工装型面，然后根据制件回弹量反复修模的问题，提高了效率和质量。研究成果可直接作为大飞机等新机研发的技术储备，在航天、风电等行业大型复杂复材零件热压罐成型中也具有广阔的应用前景。

With considering the great demands of aerosapce manufacturing industry, the key design problems of tooling for autoclave curing have been researched to satisfy the large complex composite component processing.The composite tooling lay-up method based on the equal Coefficient of Thermal Expansion(CTE) with composite part has been proposed to achieve an accurate processing of composite part.The CTE of tooling can match with the composite component by choosing the aporopriate tooling material and design the tooling broad lay-up method. Based upon the stress free temperature of composite part, the accurate tooling surface design technology was developed to predict the surface of composite tooling.This technology was researched by analysing the curing process of carbon fiber reinforced composite materials and found out the composite part shape was deteminered by tooling surface when the processing temperature reached the stress free temperature.This kind of technology can solve the tooling design problems caused by traditional design approach which repeatedly modiy the tooling surface based on the warping of composite part.At the same time, the manufacturing efficiency and the quality of composite component is increased. The research achievements can be directly applied in the the manufacturing of large complex composite structures in large passenger aircraft,aerospace products and wind power facilities.
