Hi,

      I am interested in thoughts as to reasons for using a glass fibre (Such as woven glass 2/2 twill) layer with woven carbon fibre layer in a laminate.

My thoughts are corrosion resistance of a metal part if next to the glass and cost.

What difficulties are presented ?

Any illustrations of examples.

Could twill weave glass fibre be used for skinning.  

Yes .. Glass fibre twill can be used for "skinning"  --- in a single layer it will be nearly transparent though .. it will not hide the material underneath

I have successfully "skinned" wood parts with light weight woven glassfibre, and you can not really tell that the glass is there, it just looks like a very thick varnish.

Glass fibre is non conductive, and as such one choice for a "corrosion protective layer" between CF and metal parts.  Other choices are Diolene and pure Kevlars.

"Sapere Aude"... Dare to KNOW!

The written word is the only truly efficient vehicle for transmitting a complex concept from mind to mind...

Do not adjust our mind, theres a fault in reality :-)

From a structural perspective, glass fibre is fine for skinning but not as high a performance material as carbon fibre.

Corrosion between conductive metals can be prevented with a thin layer of glass fibre or resin between the two metals.
