- Annotation: The article is devoted to improving the algorithm for constructing the trajectories of laying reinforcing filler threads in composite materials. The key problems arising in the software implementation of the algorithm considered, include determining the boundary points of the model, ensuring symmetrical partitioning into finite elements, preventing intersections of laying curves, and dependence of the thread location on the choice of starting points. The authors propose practical solutions for each of these problems, such as an algorithm for identifying boundary points using sector analysis of neighbourhoods, mesh optimisation methods in Ansys Workbench, as well as approaches to eliminating curve intersections by adjusting the accuracy parameter Δ, and creating a more uniform laying structure. The results demonstrated, use a specific model as an example, confirming the effectiveness of the proposed methods. The developed algorithm allows automating the process of constructing laying trajectories, which helps to increase the strength and stability of composite materials.
