Hi,i make carbon fibre laminates and have the following issues at some parts which get direct sunlight in the hot interior of a car

I backe the parts at an oven with elevated temperature,2hours at 40,2 hours at 60 and 2 hours at 75,after the cycle,the parts ofcourse get warm and epoxy get soft,you can hit them with your nail,is it ok or did something wrong?
