In automated carbon fiber-reinforced plastic (CFRP) lamination technologies, such as AFP, the design of the path for accurate tape application is challenging.Therefore, a molding technology that allows the use of variable tape widths and thicknesses, which are fixed in previous methods, is currently being developed.Fiber orientation and layer Ski de fond - Accessoires - Batons thickness should be optimized in a 2D plane.However, for structures with free-form surfaces, such as propellers, three-dimensional (3D) manufacturing design becomes necessary.

A method is proposed here for optimizing the fiber orientation and layer thickness of a prepreg tape for a 3D propeller model with a curved surface structure.This method enables curve boundary-agnostic tape lines, by projecting curves created on a two-dimensional plane onto a curved surface.Multi-objective optimization with displacement and weight as objective functions reduced the Sensory Toy displacement by 20.0% while maintaining strength.

These results are likely to be informative for weight reduction and manufacturing design of CFRP structural components.
