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.

High impact-resistant, reinforced fiber for leading edge protection of aerodynamic structures

A container includes one or more hollow shell assemblies, each assembly having a first hollow shell including a first inner surface to cover a portion of a pressure vessel (PV) and a second hollow shell including a second inner surface attachable to the first hollow shell. The first and/or second hollow shells may include a fiber layer that may be at least partially impregnated with resin, and an energy dissipating material that is substantially concentric with the inner surfaces of the respective shells. The first and second hollow shells are attachable to one another to define a volume for at least partially enclosing the PV, and may be overwrapped via filament winding.

Containers and methods for protecting pressure vessels

A container includes first and second hollow shells respectively including first and second inner surfaces to receive a portion of a pressure vessel (PV). The first hollow shell includes a fiber layer that is and at least partially impregnated with resin, and an energy dissipating material that is substantially concentric with the first inner surface and disposed between the first inner surface and the fiber layer. The second hollow shell includes a fiber layer that is at least partially impregnated with resin, and an energy dissipating material that is substantially concentric with the second inner surface and disposed between the second inner surface and the second fiber layer. The first and second hollow shells are attachable to one another to define a volume for at least partially enclosing the PV.
