Young's modulus as a function of temperature

Hi,
I am looking for Young's modulus of fiberglass and carbon fiber at a temperature of 500-600 ° C.
Thank you.

I think you'll need to find the specification for the specific resin used. Different resins have varying degrees of heat resistance. Most are not suited for such high temperatures.

Unless you mean for just the matting material without resin added.

Other variable factors which will modify the material properties beyond the temperature is the ratio of fiber to resin, and the orientation of the fibers.

Hi, thank you for the answer.
I attach the purpose of my experience.

The carbon fiber and fiberglass used of low quality. I am looking for an average or approximate value. My goal is to adjust this value so that results found by Solidworks correspond to my experiments.

If you want to see what kind of fibers this is the link where my proffesseurs bought them:
Carbon fiber : https://www.decathlon.fr/jonc-carbone-3-mm-x-160-cm-id_8001713.html
Fiberglass : https://www.decathlon.fr/jonc-fibre-de-verre-4mm-x-120-id_1103604.html
I think I gave all the information I have about my materials.
Thank you.

Short of testing it in a lab, you could take a guess and start with 200 GPascal.
Raising the temperature will likely lower that value, but it really depends on the material properties of the resin used to produce the rods.
The values will also depend on how the rods are wrapped, and the quality of the fiber used.
I think the only way you are going to get good data is to test some coupons yourself, or send them out to a lab.
