Research and application progress of curing tooling technology for large composite aeronautical components

Curing tooling is one of the key factors to induce the deformation of thermosetting resin matrix compo-site components. The development trend of integrated, mass, high precision and high performance of composite components for large aerospace composite material components has put forward higher requirements on the precision and life of curing tooling, and promoted the new development of tooling materials, design and manufacturing processing. However, there is still a lack of systematic review of relevant research. Therefore, contraposing the widespread demanding of high precision tooling for large aerospace composite material components, this paper summarizes the research status including interfacial functional mechanism between tooling and components, the pro-perties of tooling materials, the structural characteristics and manufacturing processing. The development from tooling material to manufacturing processing is emphasized in detail under the comprehensive consideration of manufacturing precision, efficiency and cost. Finally, the current development status of high precision tooling is summarized in aspect of materials, design and manufacturing technology for large composite components and the main research directions in the future are proposed.
