Design Optimisation of Practical Variable Stiffness and Thickness Laminates

The use of composite materials in airplanes has been increasing over the last decades, mainly due to the high strength-to-weight and stiffness-to-weight ratio of composites. Traditionally, the possible fibre angles are often restricted to 0°, ±45° and 90°, referred to as conventional laminates. However, with the rise of fibre placement machines,...
