Edison filament
Carbonised bamboo in lamps — not structural CF.
炭素繊維 · 黒鉛に近いシートの高分子由来フィラメント。火災は樹脂の話。
炭素繊維 did not arrive as a finished commodity. Edison carbon filament; Shindo/Watt 1960s PAN around Japan / UK / US still explains who makes it and which tests it sits in.
Ten dated points, five eras and three milestones below are the spine — not a complete industrial history.
Carbonised bamboo in lamps — not structural CF.
Early high-modulus experiments.
Japanese PAN-based fibre patent lineage.
UK polyacrylonitrile route at RAE Farnborough.
Fan-blade setback taught toughness.
Black plastic as status.
The workhorse tow.
Primary aero structure at scale.
Auto CF with a cost lesson.
Fibre recovery still downcycles modulus.

Knowing this timeline is how to read a mill certificate without treating 炭素繊維 as timeless.
