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-375 5.7oz 3k plain 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 single sided tack material meaning that most of the resin is on one side. This is the best for cosmetic carbon fiber parts as you will place the resin rich side onto the mold face so more resin starts on the mold surface and ensures a void free finish on the face of your part. 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.

This product is 50" wide and sold in 10 yard, 25 yard and 50 yard segments. 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 below to select the roll length.

Shelf Life/Storage 

  • 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: This product needs to be cured at 250° F for One hour. You can cure at 200° F for 2.5 hours, however you will not get the same "tg" glass transition temp (temp range where the resin changes from a hard rigid state to a more pliable "rubbery" state) of the finished part.

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. The user of this material is required to use the necessary protective equipment as directed by applicable state and federal laws when handling, curing, and grinding this material.

Shipping: This material should be shipped expedited airmail. Due to a short shelf life at room temp we suggest shipping this material via an expedited service such as UPS Overnight, 2-day or 3-day. These are guaranteed services. If these are chosen, we will ship the materials in the beginning of the week to ensure they do not sit in the shipping company warehouse over the weekend. We can send the material with insulation and icepacks at an additional cost (add $25 for ice packs and insulation). It is suggested that you ship with ice packs and 2-day airmail at a minimum. If you plan to use material within days of arrival or are OK with loosing days of shelf life, you can select any shipping method you would like, however if our minimum suggested shipping method is not chosen, we will not be held responsible for issues with material.

Custom Prepreg Options

We can have almost any of our fabrics pre-impregnated for you. Please email us for more details. 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.
