Well I asked them over and over again, whether the material is suitable for use with epoxy and they assured me it is. I didnt tell them I intend to use it in aviation since they would back right off citing liability. They also told me they export it to a finnish wind turbine manufacturer on a regular basis, they manufacture special "tension controlled" fabrics for them. The only problem is their lightest fabric is %30 heavier than what the plans call for.
