Abstract

Systems and methods are provided for fabricating and utilizing segmented hollow fibers. One embodiment is a method for fabricating a hollow fiber. The method includes disposing injection needles at orifices of a die, loading the die with a pool of molten material, driving the molten material through the orifices of the die, and iteratively injecting a gas into the molten material at the orifices via the injection needles and pausing injecting the gas as the molten material is driven through the orifices of the die, resulting in discrete hollow chambers within molten material exiting the die. The method also includes cooling the molten material into a hollow fiber that includes the discrete hollow chambers.
