Fiber steering is one of the promising capabilities of automated fiber placement (AFP) technology in manufacturing of advanced composite structures. In this work we design, manufacture and test a variable stiffness (VS) composite cylinder made by fiber steering. The bending-induced buckling performance of the VS cylinder is compared with its quasi-isotropic (QI) counterpart to investigate the improvement of the buckling capacity.
