CTE of carbon fiber composites at cryogenic tempertures

[fang54]

Do anyone know a good source to look up the CTE of Carbon fiber composite at low temperatures? I know for metallic and plastics the CTE tends to be non-linear with temperature. What about carbon-fiber?

I know there is a lot of different blends of carbon composite out there and their CTE is very small, but I just want to get a good idea of the trend at lower temp.

I generally use the Cryogenic Materials Data Handbook for such things. Of course, the CTE is going to depend not just on the carbon fiber but what plastic it is mixed in.

Volume 1 is all metals (aluminim, SS, ... )

Volume 2 has the plastics in it.
