Description
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.

How We Sell - Fabrics
Our fabrics are sold by the linear yard, with the exception of our samples which are a single 4"x4" (or 5"x7") piece. The unit price displayed is for 1 linear yard; all volume discounts will be automatically applied when selecting larger quantities of fabric when added to your shopping cart, as indicated in the table above with quantity discount ranges for units purchased.
Please purchase the number of linear yards that you require. When purchasing multiple yards of the same fabric, you will receive one continuous length of that material. We carefully take that material and roll it onto a cardboard core and wrap clear plastic or Kraft paper over it, making sure to keep the fabric in its first quality condition. We pride ourselves on having one of the best material handling crews possible.
Resin Consumption
Resin consumption is provided for the approximate amount of resin by weight 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 depends on the user’s techniques. Vacuum bagging a wet layup will improve the resin content. Too much resin will cause a weaker part, not stronger. The average rule of thumb is around 45% (+/- a couple of percent). To calculate actual resin % in your part, a burn test is used. For example, you have a part weighing 100 grams, and 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.
