Fiberglass Chopped Strand Mat 13.5oz sqyd/1.5oz sqft. This material is a fiberglass fabric which is composed of chopped strands woven into a flat matting. This matting can be torn easily and is the most common type of fiberglass used. This material was made by reputable manufacturers across the US, and their long lasting presence in the composite industry will ensure you receive a quality material.

The binder on the material is intended for use with polyester and vinylester resins. Epoxy will have a difficult time wetting out the material.

To harden this material you will need to use one of our Polyester or Vinylester Resins.

The resin consumption provided is for the approximate amount of resin by weight, contained in the final part after processing by vacuum infusion. This does not account for the resin used in the flow lines and consumables such as flow media or breather cloth. Wet-layup by hand will also have a higher resin consumption in the final part and is dependent upon users techniques. Vacuum bagging a wet layup will improve the resin content. Too much resin will cause a weaker part, NOT stronger. Average rule of thumb is around 45% (+/- a couple percent). To calculate actual resin % in your part a burn test is used. For example you have a part weighing 100 grams, you would burn off the resin which would leave the fiber behind. You should have 55 grams of fiber left when your process is working correctly. Due to the variables in processing it is hard to give an accurate amount of resin needed to purchase for making your part. However you will have waste no matter what method is used. A suggested ratio is about 1-1.5lbs of resin per lb of fabric purchased.
