摘要： The present disclosure provides an optimized designing method for a laminate preform of a ceramic matrix composite e. With overall consideration of a strength requirement of a component, a geometric shape and properties of the laminate preform, the method includes: optimizing, based on a corresponding mechanical formula, a fiber volume fraction of each laminate constituting the preform and a fiber direction in the laminate, and selecting a preferred microscopic structure for each laminate, thereby taking full advantage of material performance. The method is applicable for optimized design of various components of the ceramic matrix composite.
