A reinforced polymer is formed by combining a quantity of nano-fibers, preferably carbon nanotubes, with powders of the polymer. The mixture is heated to cause the polymer to fuse to the fibers, forming a feedstock. The feedstock is heated and forced through a die that has channels that change in direction a number of times. Each change in direction results in a high shear stress applied to the feedstock. The shear stress causes the twisted ropes of carbon nanotubes to elongate and align with each other. Rather than a die, sheet rollers may be employed to apply the shear stress.
