Abstract
A fabricating method is provided for a multilayered, nanoparticle-coated fiber material using a layer-by-layer nanoparticle-deposition system. Fabrication includes coating a fiber substrate with a first type of nanoparticle to provide a first coated layer of the multilayered, nanoparticle-coated fiber material. Fabrication also includes coating the first coated layer with a second type of nanoparticle to provide a second coated layer of the multilayered, nanoparticle-coated fiber material.

A fabricating method comprising:
- treating a surface of each of a plurality of fibers of a fiber substrate to impart an ionic charge polarity onto the surface of each fiber;
- coating the surface of each of the plurality of fibers of the fiber substrate with nanoparticles having an ionic charge polarity opposite the ionic charge polarity of the surface of each of the plurality of fibers of the fiber substrate to provide a first layer of a multilayered, nanoparticle-coated fiber material to each of the plurality of fibers in the fiber substrate;
- coating the first layer with nanoparticles having an ionic charge polarity opposite the ionic charge polarity of the first layer to provide a second layer of the multilayered, nanoparticle-coated fiber material;
- forming the multilayered, nanoparticle-coated fiber material into a desired part shape;
- subjecting the formed multilayered, nanoparticle-coated fiber material to a pyrolysis process;
- and
- performing at least one of chemical vapor infiltration or chemical vapor deposition on the pyrolyzed fiber material.
