An integrated design method of ceramic matrix composites based on feature unit assembly

Abstract

This invention discloses an integrated design method for ceramic matrix composites based on feature unit assembly. It includes the following steps: disassembling the ceramic matrix composite component into a combination of various typical feature units, determining its design structural parameters and process parameters; solving for the load data of the component based on all design structural parameters; obtaining the performance data of each feature unit according to its design structural parameters, process parameters, and load data of the corresponding region; identifying the most critical feature unit and using its performance data as the performance data of the entire component under the current design structure; selecting multiple sets of design structural parameters and process combinations that optimize the component's performance; and verifying and determining the final configuration of the component. This invention, by disassembling complex components into standard feature units and utilizing a feature unit database for performance prediction, avoids conducting numerous expensive component-level tests for each new design, shortens the design cycle, and reduces R&D costs.
