Carbon Fibre Bicycle Frame Manufacturing Process
Commonly the lug material is now also a carbon fiber composite.
Carbon fibre bicycle frame manufacturing process. Resin transfer rtm or fillament winding method used in lugged construction where pre formed carbon tubes are bonded to internal or external lugs see. Here s a condensed version of the step by step process. Like all ingredients carbon needs to be stored and maintained properly to maintain quality. 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.
The higher the quality the thinner the filament. 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. 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. 2 weave the fibres together with resin to make pre preg sheets.
Before manufacturing begins we select the specific fibers resins and weaves for each bike. Lugged frame construction and are held in place with glue. Not all carbon is created equal.
