When it comes to raw materials a very small percentage of bike builders use a rtm resin transfer mold based system where dry carbon fiber is injected with resin during the actual molding process.
Carbon fibre bicycle frame manufacturing process.
Commonly the lug material is now also a carbon fiber composite.
Resin transfer rtm or fillament winding method used in lugged construction where pre formed carbon tubes are bonded to internal or external lugs see.
Like all ingredients carbon needs to be stored and maintained properly to maintain quality.
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.
Not all carbon is created equal.
Lugged frame construction and are held in place with glue.
Before manufacturing begins we select the specific fibers resins and weaves for each bike.
Manufacturing processes vary greatly between companies and even by model but most composite bikes are made by arranging small strips right of carbon around a solid core inside a mold far.
Carbon fiber composite frames can be manufactured using the following two methods.
2 weave the fibres together with resin to make pre preg sheets.
The higher the quality the thinner the filament.
