Polycarbosilazane-Resin Polymerization Process
Process suitable for production of silicon nitride/silicon carbide fibers. High-tensile-strength silicon carbide/silicon nitride fibers prepared by pyrolyzing fibers drawn from melt of polycarbosilazane resin. Such fibers show promise as replacements for carbon fibers in high-strength composites for automotive, aerospace, and other applications where high electrical conductivity of carbon fibers makes them unsuitable.

SixNyCz Fibers for Safer Composites
Silicon nitride/silicon carbide fibers prepared by pyrolysis of polycarbosilazanes proposed substitute for carbon fibers. Silicon nitride/silicon carbide fibers tested pyrolyzed from polycarbosilazanes prepared from tris(N-methylamino) methylsilane. Polycarbosilazane resin drawn into fiber from melt, treated and pyrolyzed. Pyrolyzed fibers are shiny black. Tests show new fibers have physical properties comparable to graphite but with lower conductivity.
