Abstract
A polymer-coated carbon is coated with an aromatic polysiloxane liquid coating solution polymerized to have non-linear, ladder-like silicon to oxygen bonding. Carbon fiber or fabric coated with aromatic polysiloxane liquid polymer provides enhanced thermal protection and oxidative stability. The aromatic polysiloxane liquid polymer-coated carbon preferably includes a non-linear, ladder-like aromatic polysiloxane polymer-coated carbon such as provided by polyphenyl-siloxane polymer having the general formula R.sub.n SiO.sub.(4-n)/2, wherein R comprises phenyl radical, and n has an average value of about 0.95 to 1.05.
