A rapid design and design knowledge management system for mould of autoclave forming resin matrix composite components

Autoclave forming is an important method for manufacturing matrix composite components with large dimension and high quality. Digitization of its manufacturing process is an active research field. The quality of manufacturing process information representation has great impact on the reuse of knowledge. Therefore, based on the analysis of devices, processing parameters and mould structure requirement in autoclave forming, an ontology-based representation for matrix composite components manufacturing process is presented. It can digitally describe and store device capability parameters, process parameters, and mould structure parameters. Thus a knowledge framework for mould design of autoclave forming is presented, and on that basis a rapid design prototype system for mould is developed, in it a mould design process wizard is built to integrate the mould design process, it include input information, calculation, analysis, data storage, display the result of mould design. The outcome of this system can be used for knowledge for autoclave forming mould design storage and reuse.
