I see various builders are using carbon fiber In their construction.  I assume this means carbon bids on a fiberglass base structure in many cases.
I am suspicious that this could lead to problems due to the differing stiffness of the two.  When a structure like that is put under load, the stiffer material carries more of the load and there becomes a large stress where the different materials join.
Maybe someone has tested this and can make a recommendation for us all.
