CTE and elastic modulus of epoxy resin and AS4 carbon fiber as a function of temperature
CTE and elastic modulus of epoxy resin and AS4 carbon fiber as a function of temperature
(OP)
Hello,
I am struggling to get data for the transverse CTE and modulus of AS4 carbon fibers and Hexcel 8552 epoxy resin as a function of temperature. Do you know where could I get such data?
Thanks for your answer.

This is typically measured by companies qualifying material, and so is hard to find outside copyright.
Toray has a number for their T700 fibre at http://www.torayca.com/en/techref/index.html section 7 "Functional and Composite Properties". (37.5e-6/K.)
You might find something at the NIAR website http://www.niar.wichita.edu/agate/.

There's some numbers in this paper for carbon/PEEK. Looking at PEEK's properties the results won't be mile out from epoxy.
