This fabric has a width of 50, tow size of 3k and is woven in a 2x2 twill weave. This is the most widely used pattern in the automotive industry. This material is woven tighter than most of our competitors' fabrics. This will help ensure a straight weave and a better looking final product. This Pre-impregnated carbon fiber reinforcement makes part production efficient and allows for more complex parts to be produced vs standard infusion or vacuum bagging techniques as the epoxy is already in the fabric.
The carbon material in the prepreg is our model F-1286 6oz 3k 2x2 Twill weave that has been coated with epoxy. Prepreg is easier to use and allows you to piece sections together to create seams that look clean and professional.
To use this material just cut to shape, pull off the plastic liner, place in mold, vacuum bag the material down and ramp up the heat to 250° F for one hour and your part is done. The material has a 42% resin/fiber ratio. This material is a double sided tack material meaning that resin is on both sides.Customers attempting to do roll wrapping should use a double sided prepreg. To achieve a higher quality class A finish, we have surfacing films in clear for cosmetics and nylon reinforced for structural applications where parts will be painted.
We do not sell this by the cut yard because it is stored in a freezer and must stay frozen to comply with shelf life requirements. Please use the dropdown above to select the roll length. 0° F (standard freezer) - 1 Year. 40° F (standard fridge) - six months. 72° F (room temp) - 30 days.
It is suggested to store at 0° F or below to provide a longer shelf life. If you plan to use material faster, then you can store at a warmer temp to shorten the time it takes to get material to room temperature.
Cure time: Here is the cure schedule for a typical laminate (3-5 layers thick). On thicker laminates, you may want to slow the ramp time and hold the dewll time longer to ensure even heating throughout the part. Thermocouples on part will help you know actual part temperature and can speed up the curing process if needed. Dwell at 100° F for 15min. Dwell at 150° F for 30 min.
Dwell at 200° F for 30 min. Dwell at 250° F for 1 Hour. Application: Remove material from cold storage at least 20 hours prior to use so the material stabilizes at room temp.
Keep the material wrapped to prevent moisture from condensing on the adhesive. Cut prepreg to the correct size, remove poly film from one side and apply to part or mold.Then remove the backing paper. Continue until the desired number of plies are obtained. When your lay-up is finished, you need to cure the material in a vacuum bag placed inside an oven or autoclave. Apply at least 10psi of pressure and 250° F for one hour.
Caution: This material contains epoxy resins and amines which may cause irritation to sensitive skin. Avoid contact with eyes or skin. If contact with skin occurs, wash as soon as possible with soap and water.If contact with eyes occurs, flush with water for 15 minutes. Do not handle or use this material until Material Safety Data Sheet has been read and understood. We can have almost any of our fabrics pre-impregnated for you. We have systems that can cure at various temps from 200° F to 350° F. We can do a max width of 60.
Lead times are usually 2-3 weeks for custom prepreg. We can do single side or double sided prepreg, vary the resin % in the cloth and vary the tack level of the material. Our fabric is always rolled onto a tube to prevent distortion of the weave.
