I have a large mold that I am going to be making and I need to buy some more glass before I get started. Up till now I have been using 6oz eglass but I’m going to want something that builds a bit quicker so I don’t have to do a million layers of 6 oz on this larger mold. I am using epoxy for my mold.
What is the difference between woven roving, and the regular plain weave 6 oz cloth? I know that csm is not suitable for epoxy because of the binder, does roving have any of this binder?
as far as i know all woven fabrics are called “woven roving”. Indeed csm doesnt work with epoxy because of the binder, as for better use for a mold i would suggest twill weave instead of plain, because it’s easier to conform to curves. woven fiberglass with epoxy will make one hell of a tough mold, but is it worth the cost? compared to a csm + polyester , woven + epoxy will cost 3 times more…
The woven roving I can get is priced so low that I can’t even find the cheapest lowest priced 5 oz or what ever cheaper anywhere!
well for example, i get 2 sq. meters of 300gr csm for 6 euros, while for woven of the same weight, i get 1 sq. meter for 8 euros… so its over twice the price of csm…for me.
18oz roving costs about $5CDN per 1.1sq meter
