Systems and methods for protecting an aerodynamic structure, e.g., a wind turbine blade, rotor blade, aerodynamic aerostructure, etc., are provided. Long fiber reinforced composites having a helicoidal architecture with material aligned with a graded hardness and stiffness are used to develop an efficient and highly tailorable leading edge protection (LEP) solution with longer durability than conventional solutions while yielding lighter, and optionally, more environmentally sustainable solutions. At least a portion of the plurality of plies are helicoidally arranged relative to one another to tailor stress wave propagation speed of the aerodynamic blade and to provide load carrying strength for the aerodynamic blade.
