Hi Quick question

Is carbon cloth subject to picking up moisture while it is being stored? should I be storing it in a warm environment before laying up so that the material stays dry?

what sort of issues could I see if the cloth was left out in a workshop/shed before lay up.

All for resin infusion but I guess this question will be applicable to hand layup too.

Carbon fibre isn't inherently hygroscopic. Obviously you want to keep it dry, but it isn't going to absorb moisture from the atmosphere on a scale that will cause any issues. 

Good to know

Many thanks I will try to keep it out of puddles
