Cost of composite materials
Cost of composite materials
(OP)
Does anyone know any website with information on the cost of composite materials i.e fibres: glass/carbon/kevlar either in UD or fabric form, also their prepregs with different matrices (epoxy/cyanate ester)
Thanks
Thanks

First you get the fiber/resin cost
Second, don't forget to include any core you might use
Oh, then there are film adhesives.
And! Don't forget your consumables, peel ply, bag film, breather. These are often overlooked when ROM pricing parts for cost estimation.
Often dry fibers and prepreg tape are sold by the lb.
Prepregs fabrics are sold by the SF.
Each prepreger will be different for similar materials.
Here is a for instance. I recently quoted 2 fiber types of the same toray fiber each pre-preged by a different prepregger with a hi temp resin. the cost from one vendor was 2X the cost from the other. That the material we chose was the cheaper one, but the cost of the compatible film adhesive was 6X the cost of the more expensive fiber system.
It seems I can't even get quoted for an AS4 right now.
I will give you some ranges I have seen recently for fabrics:
Epoxy Prepreg 3.25 - 8 / sf
Cyanate Ester prepreg 11 - 25 / sf
BMI 8 - 12 / sf
But as was mentioned earlier, you should contact some prepreggers and get quotes. Even if you aren't ready to purchase. You'll get a much better idea of what's available and current cost (instead of the cost form 2003 like most of what you find on the net).
