A significant increase in the rate of composite manufacture is needed to meet demand for short-range commercial aircraft. The enabling automated manufacturing processes can, however, induce undesirable process features such as wrinkles. Additionally,

Discrete Stiffness Tailoring (DST) is a novel manufacturing concept where stiffness tailoring is achieved using discrete changes in ply angle to favourably redistribute stresses. Resulting performance increases can be exploited to potentially achieve
