Carbon Fiber 2×2 twill 3k 50″/127cm 6oz/203gsm Room Temp Stable Prepreg Double Sided (Remnant)

Description

Room Temp Stable Prepreg Carbon Fiber 3k 2×2 twill 50″ Wide Double Sided

Unlike other Pre-Preg Fabrics, this material can be stored at room temperature! No need for freezers or expensive overnight shipping any more. This Pre-impregnated carbon fiber reinforcement is stable at room temperature for an entire year. Pre-preg 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 pre-preg is our model F-1835 6oz 3k 2×2 Twill weave which uses Toray fiber to ensure the best possible appearance available.

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.

Benefits of Prepreg:

• Easy To lay in the mold, works like a vinyl sticker
• Very clean production process
• No resin to mix
• Accurate and controlled resin percentage across the entire fabric
• Harder to damage cosmetic appearance of the carbon fiber
• Easily can precut patterns on CNC cutting machine with Knife
• Can be used in equipment ranging from Ovens, Presses and Autoclaves
• Saves labor cost

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 the desired cure temperature and your part is done. The material has a 42% resin/fiber ratio. This material is a double sided tack material meaning that there is resin on both sides of the material. This will allow for better adhesion between layers during the initial layup while still offering a great cosmetic finish.

Shelf Life/Storage

• 0° F (standard freezer) – 30 months
• 72° F (room temp) – one year
• 90° F (hot shop day) – six months

It is suggested to store at 0° F or below to provide a longer shelf life and pull out the material needed. 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 between 270°F and 310°F. The hotter you can cure, the shorter the material will need to hold at max temp.

* Ramp Up and Ramp Down values apply to all three cure options.

Application: If you are freezing material then 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

We take care in shipping our items and we will never fold the fabric. Our fabric is always rolled onto a tube to prevent distortion of the weave.
