| Abstract: |
NextGen Aeronautics is proposing to develop unique carbon nanotube structural pattern patches for seamless integration with existing structural composites manufacturing methods. These patches will be transferred to prepreg plies to provide through-the-thickness enforcement to laminated composite structures around delamination prone areas. Our concept, termed as "Nano-Nails," produces similar reinforcement as mechanically fastened build up structures where rows of nails, bolts or rivets are used to pass shear and construct thicker load carrying laminated beam, column and plate structures. The proposed concept is possible because of the unique manufacturing capabilities of our team partner to create 3-D structures with unprecedented control over geometric and mechanical properties of CNT based structural forms. NextGen Aeronautics team will develop a "Nano-Nail" pattern optimized for through-the-thickness reinforcement of ply interfaces around an open hole. Proof-of-concept tests will be performed to demonstrate improvement in open-hole compression strength and interlaminar free edge delamination arresting performance of the concept. Phase II will concentrate on expanding reinforcement patterns for other loading conditions and will develop scale up manufacturing processes. We will coordinate with Navy to identify specific application and target infield testing to improve TRL to 7 in possible Phase II enhancement or Phase III. |
| Benefits: |
The technology finally developed in this program will directly benefit development of nano-level engineered advanced composite structural components. It will be used to strengthen structural hot spots. Specifically, significant benefits are anticipated in through-the-thickness strengthening of laminated composite structures. Seamless integration with polymer matrix composite manufacturing processes and localized stress patterned optimized reinforcement of areas around fastener holes, ply drop-offs, joints and free edges will improve reliability and extend life of the structures. Commercial aerospace, navel and automotive industry will benefit from the proposed technology. This is a technology with wide applications to defense and commercial markets. |
