2x2 Twill Spread Tow Carbon Fiber Fabric/Cloth 45" 12k 11.8oz/400gsm. Spread tow fabrics, sometimes referred to as Flat Tow increase the performance of your parts while enhancing the appearance. Spread tow fabrics will yield a smoother surface finish, and lighter composite parts (in upwards of 20% weight savings compared to standard woven fabrics). The fibers lay flat in the spread tow fabrics which removes the small areas in between the strands in the weave where excess resin can accumulate. It is a very small amount, however every time a carbon strand is woven over and under a perpendicular strand, it creates a bridge where just a tiny bit more resin can accumulate. In one yard of a standard 50" 3k Plain weave carbon fabric there are approx 23,400 places where the weave bridges, In a plain weave spread tow fabric (25mm tape size) that amount is reduced to about 1800 places. That is over a 90% reduction in places where excess resin can accumulate. Now you can see why you are able to achieve parts with a 20% weight savings and the true potential of these materials. That is why Nascar and F-1 Teams use these fabrics.
This fabric is made from Toray T700 12k fiber
To harden the raw fabric into a usable form, you will need the appropriate resin or epoxy for your project.
How we sell
This roll is 45" (114.3cm) wide and the fabric is sold by the linear yard. 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 over with clear plastic or Kraft paper, making sure to keep the fabric in its first quality condition. We pride ourselves as having one of the best material handing crews possible. We have most of our material available for purchase in sample swatch books per fabric category. Samples of our fabrics can be purchased by Clicking this Link.

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.
