| Abstract Scope |
Generators, motors and transformers rely on inductors. Almost 100% of electrical energy is produced by generators. Motors consume ~65% of electricity. This paper concerns coil-less carbon fiber composites as structural inductors and provides the science base for tailoring composites for inductance. Single carbon fiber exhibits volumetric inductance that is 1,100 times that of the dimension-based calculated value, due to the nanostructure. Fiber-fiber contacts contribute to 91% of the tow (12,000-fiber bundle) inductance. The composite’s volumetric inductance and resistance are higher than those of a tow, due to the composite structure. The surface inductance (a new scientific quantity) is huge compared to the volumetric inductance. The composite volumetric inductance increases with the number of laminae, due to the interlaminar interface. The inductance, resistivity and permittivity of composite are higher for 45° direction than 0° direction of a biaxially woven composite. The inductance decreases with increasing width and increases with increasing length. |
