between 2 different fiberglass, one with more yarn/yarp
different amount of resin?
I think not. As long as both are the same weight. There may be a difference in wetting, though (one being easier to wet than the other) and/or in “wrapability”…
oh, tnx
I thinking that “more fiber less resin”
At same weight, fabric with high density of yarn are slightly thinner and can be saturate with less resin. for exemple twill fabrics are in general tightly woven, they need less resin than same weight of plain open wave but they are more difficult to saturate. Some plain wave are made with flat yarn tightly woven they are less drapable but use less resin and are impact stronger.
Sorry for my franglish
franglish… and me? Italianish?
