I am an undergraduate student at Clemson University and am doing a
project on high temperature composite materials (>4000 F). i am looking
at a variety of systems such as nicalon, graphite, tungsten, and SiC
fibers with various coatings such as carbon, yttria, in matrices of LAS,
SiC, Ti3Al3, hafnium oxide, and iridium. Important factors are high
modulus, low density, low creep, oxidation resistance, consistent CTE,
and chemical compatability. Any help or suggestions on where to start
would be greatly appreciated.

I've watched a sample of carbon/carbon bond hand-held in a propane-air
torch (2200 F) once coated with Starlite polymer. Starlite's been
tested into and beyond the temperature range you're interested in, and
it's got the other good properties you mention. But it's not available
commercially yet. It's nearing commercial introduction in, of all
things, a polyurethane foam formula for fireproof cushions and
mattresses!

Steve,

Where did you obtain the Starlite coated sample? Many of us in the
ceramics community have heard tantalizing bits of information about this
material. But it seems to be more legend, than reality. Any direct
contacts, leads, or recent information would be welcome.

rick,

thanks for the note on the "charm.net" web page. Looking at what's
reported there, it reminds me of the "cold fusion" phenomenon in the
late 80's.
