Free Form Fibers has been granted U.S. patent # 10,876,227 B2 for the fabrication of fibers with specific elemental materials added to the fiber composition that drive enhanced performance, such as high temperature creep resistance.
Patent abstract: A multi-composition fiber is provided including a primary fiber material and an elemental additive material deposited on grain boundaries between adjacent crystalline domains of the primary fiber material. A method of making a multi-composition fiber is also provided, which includes providing a precursor laden environment, and promoting fiber growth using laser heating. The precursor laden environment includes a primary precursor material and an elemental precursor material.
