The proposed program involves the development of a novel additive fiber reinforced composite fabrication technology capable of supporting the design and manufacturing of lightweight, robust cylindrical structures. Such structures (which have wall thicknesses of multiple inches, diameters in excess of 2 feet, and lengths in excess of 30 feet) are capable of functioning in a high torque environment, are damage tolerant, exhibit environmental durability, are abrasion resistant, and exhibit compatibility with metallic components, all critical qualities for drive components on Naval platforms.
Benefit: Beyond NAVSEA applications, this technology is being envisioned for use in other maritime concerns (e.g., A-class ships, commercial shipping platforms, etc.), the wind turbine industry, as well as energy and infrastructure applications requiring large pipes and/or conduits.
