CF delaminates in the heat....?
I live in the hot bit of California... the inside of the car gets to 120F (or more) sometimes... I see CF bikes in backs of cars and have heard that heat can delaminate CF. Should some riders now be scared, or am I now starting an irresponsible rumor?

Carbon Fiber is made with a thermosetting resin. A thermoset is a polymer that is heat-cured, and while it is being cured, it's melting point rises above the curing temperature, causing it to harden. Carbon fiber is usually cured somewhere in the 300-400 degrees F range, so it's melting temp is guaranteed to be at least that high.
Thermoplastics are the plastics that melt, then harden as they cool.
Thermosets are initially soft, then they harden as they are heated (unless they get really, really, super hot).

I think you're starting an irresponsible rumor. I've been riding an OCLV through Sacramento summers since '00. No delamination.

point i meant to make was....it's not like plastic that can melt in the sun. it'd take more than 87degrees to melt it.

Yay. Another thread espousing the dangers of CF melting. If I ever ride my bike in 300 degree heat and it melts, boy will I have pie on my face.
