Here s a condensed version of the step by step process.
Carbon fibre bicycle frame manufacturing process.
1 it takes 5 000 to 12 000 carbon filaments each between five and seven micrometers thick to make a single carbon fibre.
Carbon fiber composite frames can be manufactured using the following two methods.
Resin transfer rtm or fillament winding method used in lugged construction where pre formed carbon tubes are bonded to internal or external lugs see.
Before manufacturing begins we select the specific fibers resins and weaves for each bike.
Commonly the lug material is now also a carbon fiber composite.
Not all carbon is created equal.
Just as important as the carbon we select is the fiber orientation or layup schedule development which is how the carbon is wrapped or placed on the frame.
2 weave the fibres together with resin to make pre preg sheets.
The higher the quality the thinner the filament.
Most frame manufacturers build frames with sheets of carbon fibre that is pre impregnated with uncured resin better known as pre preg applied to a non stick paper backing and shipped on large.
Lugged frame construction and are held in place with glue.
