2x2 Twill Carbon Fiber Fabric/Cloth 3k 5.8oz/197gsm HEXCEL 284 PRIMETEX. This fabric has a special process applied to it that spreads out the fibers to create a fabric with over 99% fiber coverage, thus eliminating nearly all gaps in the weave of the fabric. Not only is this is one of the nicest looking carbon fiber we offer, but this Primetex finish also makes a more even part with minimal excess resin deposits. This fabric is perfect for manufacturing parts and also is the same style of fabric used in the high dollar OEM carbon fiber parts. This material gives the best cosmetic appearance available while remaining easily drapeable. Material is woven here in the USA to ensure high quality standards. Fabric is produced by Hexcel.
First Quality Remnants:
First Quality Fabric Remnant Rolls are short rolls of fabric, which have no defects in them. These remnant rolls are either left over fabric from the end of a roll, or sections of fabric which were cut at the wrong length for a specific order. So instead of discarding the short roll, we package it up and sell it as a First Quality Remnant Roll. These First Quality Remnant Rolls are sold at 20% off of the retail price of that fabric.
Second Quality Remnants:
Second Quality Fabric Remnant Rolls are short rolls of fabric, which have a defect in the woven fabric in them. These remnant rolls are cut out of the standard fabrics we sell, but from sections of the rolls that have some defects in them. These defects make them not good to use if you want to make cosmetic parts, which have perfect woven fabric in them, but can be used as the inner layers of your parts, or if you are making small parts and can cut around the defects. These Second Quality Remnant Rolls are sold at 25% off of the retail price of that fabric.
All remnant rolls are rounded DOWN to the nearest ½ yard. So a remnant listed as 0.5 yards may actually be between 18” and 35” in length and a remnant listed at 2.0 yards may actually be between 72” and 89” in length.
PrimeTex® is a range of carbon fabrics which have been processed for a smooth, closed weave and uniform cosmetic appearance. The fiber tows are spread in both the warp and weft direction for unique aesthetic appeal. PrimeTex® fabrics are more uniform as the filaments in each tow are spread out creating a thinner and more closely woven fabric that provides better mechanicals and less porosity in a composite. It can also be used to lower the mass in a composite where lighter weight is the key characteristic.
- Patented technology with fibers spread in both the warp and weft direction
- PrimeTex® spreading process improves closure factor compared to conventional weaving process (depending on carbon tow and Fabric Areal Weight)
- Use of higher K tow for a given Fabric Areal Weight (FAW)
- Weight saving: Up to 20% at affordable cost when replacing HS3K by IM12K
- Uniform weave and gap-free structure: porosity reduced / less labor for part finishing
- Excellent water tightness when used in honeycomb sandwich structures
- Laminate mechanical properties maintained after spreading process with reduced variability thanks to homogenous resin/fiber distribution
- Aircraft and helicopter sandwich structures and thin monolithic parts
- UAV/Light Aircraft market targeted by cost to weight
- Automotive structures (e.g. BMW roof)
- Sports equipment (e.g. skis)
To harden the raw fabric into a usable form, you will need the appropriate resin or epoxy for your project.

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.
