Hello,

I'm looking to run a finite element analysis to determine which of your standard tubes would be most suitable for use as wishbones. Would it be possible to get information on the lay-up of your standard tubes? Particularly the 14mm ID and 18mm ID tubes.

Also I'm a bit unfamiliar with the roll wrapping process and was wondering if the process electrically insulates the tube on the inside in any way so as to avoid corrosion as it shall be in contact with aluminium.

Lastly I was hoping to find out if you offer a tube cutting service before sending the tubes out for delivery as I would not be confident in our ability to cut the tubes in our workshop here.

Thanks,

Stuart

Hi Paul,

Alike Stuart, I too, am on the process of selecting our wishbones and modelling them through FEA.
The information you gave is indeed very useful, although it is unclear to me the layers of 300gsm E-Glass... what is E-glass??? Is it an epoxy of some sort? I thought the rods would have been mostly in carbon fibre...
What kind of Modulus would the E-glass layers have?

Cheers,
João

P.S.: it too is for a Formula student car

Hi João,

E-Glass is a type of glass reinforcement, it is pre-preg E-glass that is used along side the pre-preg carbon fibre. It represents only a 2/5 proportion of the reinforcement in our carbon fibre tubes and is used because it has properties which aid the manufacturing process whilst at the same time providing strength. Remember that the carbon used is high modulus T700 to more than compensate.
