Carbon Fiber Fasteners for F1?

ginsu · Post 27 Jul 2006, 09:44

I just recently found out about carbon fiber bolts being used on very high end bicycles. I was wondering if anybody has heard of these being used in F1. It seems like it has a very dramatic potential for weight savings.

There are many types of carbon based materials, the actual name for this type of carbon is 'CFM Peek'.
You may have heard of 'Carbon Peek', which has been used in many F1 and fighter Aircraft applications in the past, but 'CFM Peek' is a material developed around a new manufacturing process.

In this process the manufacturer is able to control the orientation of separate carbon fibres within the component, creating a part many times stronger than standard 'Carbon Peek'. In fact these bolts have a proven higher yeld strength than steel! Although they are lighter than aluminium...

do you have a web link these look like perfect solar car bolts

Lighter, stronger, and most definitely a lot more expensive.

cost is negligible on a solar car though weight is much more important

I wonder if any FSAE team will use this.....Delft perhaps?

neither is Titanium and carbon everything else and we see plenty of those around......

this may be the breakthrough for Delft to make a sub 250lb car(their 06 weighs 125kg, or ~275lb

)lol

good point but i did make a carbon body weigh 1/5 of its fiber glass counter part

and depending how you price the bolts they would not be so bad

They seem pretty expensive to me, they are from 'poshbikes.com' which is located in the UK so I'm sure you can call them and see who their supplier is

Sizes: M5 x 20 Torx-hex head / M5 x 20 Countersink head / M6 x 30 Torx-hex head screws, (Other sizes may be available shortly)
Weight: M5 x 20 Torx-hex head 0.7grams / M5 x 20 Countersink head 0.7grams / M6 x 30 Torx-hex head 1.3grams
Price: M5 £36.00 for 4off / M6 £44.00 for 4off (Sold only in packs of 4)

Also, please read their disclaimer, this is a very new product!

Use: To replace all standard Din M5 (5mm) & M6 (6mm) screws where the use of aluminium screws is permitted. Although these bolts have proven to be strong enough for most applications, these are still a very new product, and you should limit their use to items such as: bottle cage bolts, front mech. bolts, cable grip bolts etc...

There does seem to be a very significant weight savings depending on how many bolts you use.

M6x15 mm

CrMo / Ti / Al / Carbon

16g / 10g / 5g / >1.3g (M6x30)
