Carbon fibre in 1350: Ageing

Scores compare Carbon fibre with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates. Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.

Carbon fibre (C (turbostratic graphite)) is a family of grades whose density ~1.8 g/cm³ fibre, heat band sublimes; resin burns, and fire letter fibre A1-ish; CFRP follows the matrix. Carbon fibre is sold as grades, not as a single substance. Chemistry C (turbostratic graphite), density ~1.8 g/cm³ fibre, heat band sublimes; resin burns.

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.
