Products – Free Form Fibers

Free Form Fibers offers you a wide range of materials, resulting from the process flexibility of Laser Chemical Vapor Deposition (LCVD).

Drawing upon the broad availability of CVD precursor gases to deposit material compositions, this CVD database is extensive, and has been proven over multiple generations in varying high-performance marketplaces.

FFF has demonstrated a range of fiber compositions, including silicon carbide (SiC), boron (B), tungsten carbide (WC), boron carbide (BxC), and carbon in fiber form, and boron nitride (BN), carbon (C), hafnium carbide (HfC) and SiC as coatings on the fibers. In addition, novel oxide compositions and other custom formulations are available, based up years of LCVD experience and the long history of CVD technology.

Fibers

Fibers are fabricated in a range of lengths, from less than ¼” to 1 ½” for discontinuous uses, and in continuous lengths for select compositions. Short fibers are converted into preforms for uses such as ceramic matrix composites (CMC’s), in discontinuous (random orientation) distribution within nonwoven veils. Fibers are also suitable for conventional downstream composites processing, such as textile conversion, pre-impregnation, sheet molding and bulk molding, and pultrusion.

Powders

Working with industry particle size reduction experts and implementing internal capabilities, Free Form Fibers created novel powders, available from any of the fiber compositions within our portfolio. These powders offer significantly enhanced purity versus state-of-the-art, as they are derived from stoichiometric Laser Chemical Vapor Deposition (LCVD) products, and only processed in controlled milling systems. The products are suitable for a range of powder applications such as additive manufacturing or 3D printing, as a pre-ceramic polymer additive, and sublimation into high purity boules (ingots) for semiconductor manufacturing.

Preforms

Free Form Fibers has partnered with key industry processors to create novel non-woven preforms in lightweight veils, mats, and dense felts, to offer ceramic composites manufacturers a three-dimensional architecture solution for their processing. In addition, various textile reinforcement concepts are under development to offer conventional composites processing techniques.
