Publication number: 20210253434Abstract: A method and apparatus for forming a plurality of fibers from (e.g., CVD) precursors, including a reactor adapted to grow a plurality of individual fibers; and a plurality of independently controllable lasers, each laser of the plurality of lasers growing a respective fiber. A high performance fiber (HPF) structure, including a plurality of fibers arranged in the structure; a matrix disposed between the fibers; wherein a multilayer coating is provided along the surfaces of at least some of the fibers with an inner layer region having a sheet-like strength; and an outer layer region, having a particle-like strength, such that any cracks propagating toward the outer layer from the matrix propagate along the outer layer and back into the matrix, thereby preventing the cracks from approaching the fibers.Type: ApplicationFiled: November 2, 2020Publication date: August 19, 2021Applicant: FREE FORM FIBERS, LLCInventors: Joseph PEGNA, John L. SCHNEITER, Kirk L. WILLIAMS, Ramkiran GODUGUCHINTA
