Carbon Fiber Reinforced

The effects of fiber orientation and volume fraction on electrical conductivity of unidirectional carbon fiber reinforced polymer (CFRP) were investigated. The unidirectional CFRP shows strong anisotropy in electrical properties. Composites with higher fiber volume fraction possess higher electrical conductivity, since the fibers are the only current path in the composites. Additionally, carbon nanotubes (CNTs) were mixed into the resin by high-pressure microfluidizer to improve the electrical properties of the composites. Results show that the electrical conductivity of the polymer matrix has been dramatically improved. The conductivity of CNTs modified CFRP composites is improved along fiber direction, while it remains at the same level in the transverse to fiber direction.
