An explicit topology optimization method for the stiffener layout of composite stiffened panels is proposed based on moving morphable components (MMCs). The skin and stiffeners are considered as panels with different bending stiffnesses, with the use of equivalent stiffness method. Then the location and geometric properties of composite stiffeners are determined by several MMCs to perform topology optimization, which can greatly simplify the finite element model. With the objective of maximizing structural stiffness, several typical cases with various loading and boundary conditions are selected as numerical examples to demonstrate the proposed method. The numerical examples illustrate that the proposed method can provide clear stiffener layout and explicit geometry information, which is not limited within the framework of parameter and size optimization. The mechanical properties of composite stiffened panels can be fully enhanced.
