The cost of a carbon fiber car chassis

I worked on carbon fiber elements for formula SAE. Total cost depends on the quality and amount of used materials - carbon fiber, epoxy resin, hardener. For vacuum infusion process you will also need molds, infusion mesh, infusion spirals, peel-ply, silicone bags etc. Vacuum pump and oven/autoclave can be expensive, but they are one-off costs.

If it is your first time with carbon fiber composites, watch some tutorials on YouTube. For safety reasons, always wear latex gloves when you use epoxy resin and dust mask during cutting the material.

Thanks X. :smile:

But did you folks use CF for the chassis of your SAE cars? Seems like a strange match of properties to requirements, especially for any type of volume production...

Does that mean this? https://en.wikipedia.org/wiki/Formula_SAE

That race sounds like something needing lots of money. Wikipedia talks about funraising and corporate sponsors, but it does not give any numbers for the budgets of these teams. One thing lacking from this thread is an order-of-magnitude guess for the budget. We don't know if the original post envisions a one thousand dollar budget or one million.

Perhaps you can help with your knowledge of formula SAE competition. I'll repeat the original question.

So what do you think? How much does it cost to produce an electromobile car chassis with carbonfiber?

We didn't use carbon fiber for chassis. We used it for external bodywork, aerodynamic devices such as front wing, rear wing, and other elemets, for example steering wheel. Some teams, which have more experience, build carbon fiber monocoque that can decrease the amount of steel.

Yes :smile:
Most of the costs were covered by sponsors. It's hard to say how much it cost. A lot of stuff we received for free and we had many discounts . Whole vehicle cost about 15000$, while aerodynamics budget was 2000$.

you can probably use aircraft grade aluminum
or a Titanium tubing frame for an even better strength-to-weight ratio. Kinda pricey though and harder to work.
