“…Achieving excellent mechanical performance of fiber-reinforced composites requires a high degree of reinforcement alignment, low void and defect content, high fiber concentration and a strong reinforcement/matrix interface. These principles also apply on CNT-reinforced composites. , In this research, the CNT yarn filament winding process previously reported by our group was modified to manufacture unidirectional CNT yarn laminates with a high degree of CNT alignment and dense packing. As shown in Figure a, the yarns were continually wound under tension onto a multifunctional mandrel.…”

An approach is established for fabricating high-strength and highstiffness composite laminates with continuous carbon nanotube (CNT) yarns for scaled-up mechanical tests and potential aerospace structure applications. Continuous CNT yarns with up to 80% degree of nanotube alignment and a unique self-assembled graphitic CNT packing result in their specific tensile strengths of 1.77 ± 0.07 N/tex and an apparent specific modulus of 92.6 ± 3.2 N/ tex. Unidirectional CNT yarn reinforced composite laminates with a CNT concentration of greater than 80 wt % and minimal microscale voids are fabricated using filament winding and aerospace-grade resin matrices. A specific tensile strength of up to 1.71 GPa/(g cm −3 ) and specific modulus of 256 GPa/(g cm −3 ) are realized; the specific modulus exceeds current state-of-the-art unidirectional carbon fiber composite laminates. The specific modulus of the laminates is 2.76 times greater than the specific modulus of the constituent CNT yarns, a phenomenon not observed in carbon fiber reinforced composites. The results demonstrate an effective approach for fabricating high-strength CNT yarns into composites for applications that require specific tensile modulus properties that are significantly beyond state-of-the-art carbon fiber composites and potentially open an unexplored performance region in the Ashby chart for composite material applications.

A novel approach is established for fabricating high-strength and high-stiffness composite laminates with continuous carbon nanotube (CNT) yarns for scaled-up mechanical tests and potential engineering applications. Continuous CNT yarns with up to 80% degree of nanotube alignment and a unique self-assembled graphitic CNT packing result in their specific tensile strengths up to 1.9 N/tex. Unidirectional CNT yarn reinforced composite laminates with a CNT concentration of greater than 80 wt.% and minimal microscale voids are fabricated using filament winding and aerospace-grade resin matrices. A specific tensile strength of up to 1.71 GPa/(g cm-3) and a specific modulus of 256 GPa/(g cm-3) are realized; the specific modulus exceeds current state-of-the-art IM7, T1100G and even M60J unidirectional carbon fiber composite laminates. The results demonstrate an effective approach transferring high-strength CNT yarns into composites for applications that require specific tensile modulus properties that are significantly beyond state-of-the-art carbon fiber composites, and potentially open a new performance region in the Ashby chart for composite material applications.
