Research Abstract |
We studied mechanical properties of carbon nanotube (CNT) yarns and CNT composites reinforced by the CNT yarns. A carbon nanotube (CNT) web, drawn from a densely grown CNT array, was twisted to form a spun CNT yarn. No chemical binder materials was used to bind CNTs, and CNTs were connected by van der Waals forces. By condensing CNTs in a yarn, tensile strength and stiffness were improved. The CNT yarns were used in CNT/epoxy composites as reinforcing materials. From tensile tests and observation of fracture surfaces, we found that a CNT yarn composite is not reinforced by CNT yarns but by single CNTs dispersed in epoxy matrix.
