Carbon Fibre is wonderfully stiff and horribly expensive. Diolen (like Kevlar but cheaper) is wonderfully impact resistant but a bit flexy. I was thinking of laying up a couple of my car panels with 1 or 2 ply of CF on the outside and 1 or 2 ply of Diolen on the inside.
My thinking is that I get stiffness from the CF with some flex or impact resistance from the Diolen.
My concern is that the CF will remain brittle so that if there is any impact the Diolen will flex and the CF will fail or the whole thing will delaminate.
Thoughts?
I am disappointed.
The Carbon Fabricators group were quicker that STW to answer.
It is a sign of the times. I blame BREXIT
IIRC You can get 'hybrid' woven Carbon/Diolene which is cheaper per m^2 but still lets you have the twill/weave look on parts once finished, id just put Carbon over woven fibreglass TBH if it's mostly aesthetic. It's only worth adding Kevlar/Diolene/aramid plys if you're after it holding together following a crunch.
I have some Diolen i ordered for the undertray and it was suggested i use glass/carbon to give the undertray more stiffness.
I just wondered if it was worth using what's left on other panels.
The general concensus is NO. It is not nice to wet up and the cut edges always look frayed. Also, unless it is the surface layer then there is little benefit.
I will keep it for the wheel arch liners as originally planned
