Carbon fibre in 1963: Watt RAE · 356

This atlas treats Carbon fibre as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: high along fibre; low through-thickness in composites. Insulation score 24/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: fibre A1-ish; CFRP follows the matrix. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.

Origin: Edison carbon filament; Shindo/Watt 1960s PAN, Japan / UK / US. The process chapter follows feedstock → conversion → forming → finish → install. Uses span buildings to defence / safety. Pairings matter: graphene. Circularity mark 26/100. Ask which scrap, which certificate, which year.

Related atlas entries, a short glossary, and three threads that keep Carbon fibre honest. The 2-D cousin in the same carbon family. The metal CFRP replaced in aero skins. EN 13501-1 reaction-to-fire letter (A1–F), not a wall rating. Declared performance after blowing-agent or moisture drift.
