Laminate resin weight and volume fraction

[jacobe]

Good evening

I have searched all over the net and the forum and cannot seem to find this information.

I have a carbon prepreg that has 50% resin by weight, how do I calculate the fibre volume fraction?

Help would be very appreciated.

Thanks

Jacobe,

The density of carbon is about 1.7, resins are a little more variable, usually around 1.1 or so.

Hi Yoke

Thanks for your reply, I have all the relevant data I am trying to get hold of the formula to calculate the Volume Fraction, do you have this?
