Carbon-nanotube-reinforced, single electrospun PMMA nanofibers (see figure) exhibit an improved Young's modulus and tensile strength relative to unreinforced PMMA nanofibers. The Young's modulus data fits well with the theoretical prediction of the Halpin–Tsai equation. The tensile strength data shows a relatively large variability, which can adequately be fitted by Poisson–Weibull statistics.
