Description
This fabric is made from Hexcel AS4 Yarn – This fabric has a width of 42″, tow size of 3k and is woven in a plain weave.
Hexcel has carbon fabrics with interwoven wires for lightning strike applications where both structural integrity and lightning protection are required in a single ply. Standard plain weave designs are available (IWWF) where the wire is woven inside the weave next to an adjacent carbon tow, as well as the more elaborate pattern designs like our patented “double weave”, where the woven wire is 92 percent on the surface of the carbon weave.
This roll is 42″ (107cm) wide and the fabric is sold by the linear yard.

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.
