Fiber-reinforced composites are crucial in many different industries due to their high strength-to-weight ratio. Automated Fiber Placement (AFP) enables precise deposition of carbon fiber tapes to create laminates, yet fixed fiber orientations often misalign with complex aerospace load paths, leading to suboptimal load transfer and higher weight of the component. Aligning fibers with actual load paths enhances performance by improving load transmission thus reducing thickness of the laminate. This paper introduces a path planning method that generates curvilinear fiber paths using Finite Element Analysis (FEA) results. These paths align with load directions while adhering to AFP manufacturing constraints, ensuring a defect-free production.

摘要

Fiber-reinforced composites are crucial in many different industries due to their high strength-to-weight ratio. Automated Fiber Placement (AFP) enables precise deposition of carbon fiber tapes to create laminates, yet fixed fiber orientations often misalign with complex aerospace load paths, leading to suboptimal load transfer and higher weight of the component. Aligning fibers with actual load paths enhances performance by improving load transmission thus reducing thickness of the laminate. This paper introduces a path planning method that generates curvilinear fiber paths using Finite Element Analysis (FEA) results. These paths align with load directions while adhering to AFP manufacturing constraints, ensuring a defect-free production.
