The latest composite manufacturing technologies such as automatic fibre/tape placement have enlarged the design space of composite structures tremendously. However, this also makes the task of finding the optimal design very challenging with classical means, certainly when taking structural stability, failure and manufacturing constraints into account. In this project, we aim to explore latest ML and QC technologies to set up new optimization algorithms for composites design.

Extending and improving in-house optimization package(lightworks) and solver(PreDocs)(analytical cross section approach in combination with a 1D FEM) for load calculation and individual thickness optimization of woven fabrics in Python framework. Additionally, manufacturing, a bending and twist constraint applicable for constrained structural optimization (using NLopt library) of wings and blades was also implemented. Determining convex feasible regions in general design space of 12 lamination parameters by coining a new term ’lumped laminates’. This would enable use of unconventional ply orientations to make full use of anisotropy. etermining convex feasible regions in general design space of 12 lamination parameters by coining a new term 'lumped laminates'.
