01 Feedstock
Ore, monomer, fibre, mineral or scrap that can legally become Carbon fibre.
Carbon fibre · Polymer-derived filaments with graphite-like sheets — aero, bikes and a fire story that is about the resin, not the fibre.
Making Carbon fibre is a chain: feedstock, conversion (Edison carbon filament; Shindo/Watt 1960s PAN), forming, heat, finish, install.

Cast, spin, weave, sinter, foam, laminate or coat — the step that sets anisotropy.
Temper, vulcanise, calcine or dry: skip it and the datasheet is fiction.
Coatings, sizings, facers, galvanizing, anodising, painting.
Fasteners, adhesives, DFT, compression, dryness — site quality is a material property.
Virgin route around Japan / UK / US.
Recycling exists but quality or energy often disappoints.
High-spec grades leave the commodity mill.
Coatings, sprays, casts — the factory is sometimes a jobsite.
Feedstock to installed product.
Energy in, class out.
Melting/softening sublimes; resin burns; conductivity high along fibre; low through-thickness in composites.
Moisture, UV, chlorides, alkalis or oxygen — pick the one that actually kills Carbon fibre.
Fire class fibre A1-ish; CFRP follows the matrix is a starting letter, not a wall rating.
Process energy and scrap quality belong in the carbon passport, not in a footnote.
A one-atom carbon sheet — Nobel-era physics, composites hype, and a few honest electronics and barrier uses.
Overall 50 ☁️A nanoscale silica sponge — among the lowest solid λ values, fragile unless blanketed, and A1 when purely inorganic.
Overall 60 🩺Near-equiatomic Ni–Ti that remembers shape and super-elasticates — stents, orthodontics and actuators.
Overall 48 ☀️ABX3 halide crystals that jumped laboratory solar efficiency — still fighting humidity, lead and lifetime.
