Keywords: chiral truss-core airfoil, morphing, composite materials, manufacturing

Chiral topologies allow to implement morphing capabilities in airfoil structures. Moving from previous results obtained with light alloy chiral cores, the paper presents the design of composite chiral structures, setting up their manufacturing process. The stiffness and the strength of composite chiral cells are then numerically and experimentally evaluated.
