碳纤维 is one of 32 materials in this atlas, grouped under advanced: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue.

Scores compare 碳纤维 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.

Deep dive: 碳纤维

碳纤维 (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.

What “the material” actually is

碳纤维 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 碳纤维 as a system: mill route, coatings, tests and the cavity it sits in.

Heat, fire and insulation

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.

How it is made and used

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.

Market and circularity

Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.

Circularity mark 26/100. Ask which scrap, which certificate, which year.

常见问题

Is 碳纤维 non-combustible?
Declared reaction class in this atlas: fibre A1-ish; CFRP follows the matrix. Assemblies still need resistance tests.
Does 碳纤维 insulate?
Thermal mark 24/100 versus the atlas. Conductivity note: high along fibre; low through-thickness in composites.
What is the density band?
~1.8 g/cm³ fibre
How is it made?
Origin story: Edison carbon filament; Shindo/Watt 1960s PAN (Japan / UK / US).
Can it be recycled?
Circularity mark 26/100 — editorial, route-specific.
Typical melting or failure heat?
sublimes; resin burns
What should it be paired with?
graphene: The 2-D cousin in the same carbon family.
Where is it specified?
Buildings, transport, energy and consumer goods — see the uses chapter.
