The strength wand modulus will drop off pretty quickly as the heat gets above the HDT. The core of our birds are quite resistant to flame since phenolics are inherantly very good as flame barriers, however this is negated largely due to their very low mass and their open cells. You can get structural phenolic core with phenolic face panels. It's used a lot in the airlines for interior panels which must meet FAR 25.853 (?) which dictates flammability standards to section 121 operators, (commercial aircraft) for interior components. I have a buch of the panel around which isn't as good as epoxy but not too bad either. Dan Newland
