CFRP, the epoxy component, is full of over 90 chemicals and this is why it was banned by the FAA finally from A/C interiors due to FST (Fire, Smoke and Toxicity) hazards back in the 70's due to numerous aircrew and passenger deaths deaths from FST. I worked on the problem between 1960's and 1970's
A recent CFRP crash example was in Guam a few years ago involving the B-2A. The fuel fire was extinguished within less than 30 minutes, but the wreckage continued to burn for over two days in spite of the efforts of over 60 trained USAF fire personnel due to continuing hot spots and flare ups. This is fully documented by USAF in their incident report, but FAA and Boeing ignored my protests as they had my earlier inputs and protests concerning 787 crashworthiness proposed SC's.
