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

Another point to be aware of is that if it is stored in a cold and damp place, although the carbon itself may be fine, ensure the fabric is fully dry and back to room temperature before use as moisture can play havoc with resin curing and clarity of the resin.

Hi Warren

many thanks I suspected there would be some effect on the resin if using a fabric which had been left out. but it is good to be confirmed,

Is there any ideal storage condtions to keep the fabric in prior to use?
