JPower210 Posted May 17, 2017 Report Share Posted May 17, 2017 Does anyone know of a good source for fiberglass cloth info? For example, what's the difference between 1800 and 7500 "style" mean in 10 oz. cloth? I have been googling, but have not found a good comprehensive guide. Thanks!

PAR Posted May 17, 2017 Report Share Posted May 17, 2017 Most fabric manufactures have their own system to ID the various fabrics, though some commonalities exist, such as with "combo" fabrics like 1708. This is a 17 ounce fabric that's lightly bonded to 8 ounce mat. 1800 suggests it a straight 18 ounce fabric. There are different types of fabrics too, just to add to the confusion, such as weave type, fiber orientation, etc. Generally, these fabrics fall into a few different categories: mat, woven cloth (like the material in your tee shirt), directional fabrics and combo fabrics (more than one fabric in the same roll). These get broken down into specifics, such as weight, fiber orientation, etc. http://www.diy-fiberglass-boat-repair.com/ http://www.shopmaninc.com/fiberglass.html Download the free "user's guides" from westsystem.com, the "epoxy book" from system three.com and the "boatbuilding handbook" from westsystem.com for a more comprehensive listing. 1 Quote Link to comment Share on other sites More sharing options...
JPower210 Posted May 17, 2017 Author Report Share Posted May 17, 2017 Thanks Par- Those are helpful resources. I am pretty comfortable with most of the descriptions, and uses, but still have questions when it comes to some of the more arcane descriptions, like style numbers. But, I think I found some answers by going to the fiberglass cloth manufacturer website versus the retailers. JP Quote Link to comment Share on other sites More sharing options...
