So, apparently CF is not heat resistant?
http://en.wikipedia.org/wiki/Carbon_(fiber)
The properties of carbon fibers, such as high flexibility, high tensile strength, low weight, high resistance,
high temperature tolerance and low thermal expansion, make them very popular in aerospace, civil engineering, military, and motorsports, along with other competition sports. However, they are relatively expensive when compared to similar fibers, such as
glass fibers or plastic fibers.
