Hi fiberglassers,
I am estimating the non-load-bearing weight of an enclosed wing and need the benefit of your experience.
(By non-load-bearing, I mean neglecting spars, sparcaps, and torsion boxes.) This is simply one or more layers of fiberglass epoxied over styrofoam core.
I understand the styrofoam weighs 2# per cubic foot. The S2 glass-woven 2533 weighs 5.4 oz. per sq. yd. dry. How much should I figure it weighs for 2 plies after epoxying ? What about 3 plies after epoxying ? I'm talking about cured weight.
I understand vacuum-bagging reduces the weight by 25%, but I don't plan on using that for my first attempt.
