  1. 1. Prepping Your Carbon Fiber Parts How To: Prep Your Carbon Fiber Parts /rc-how-tos/prep-your-carbon-fiber-parts/ Most high-end on- and off-road RC cars and trucks come with carbon fiber (CF) components. These components are lightweight and super-strong2 key factors in keeping your ride fast and nimble. These parts are cut from a large sheet and, once completed, often have sharp, un-prepared edges. These edges can be fragile in a crash and the carbon fiber plate can de-laminate, causing the part to weaken and fail. To combat that, there is a process of sealing the sides of the CF parts. This involves taking a small amount of super glue and applying it to edge of the parts, effectively sealing the edges. This will allow the parts to take much more abuse before failing. Items Needed: A file. You dont need anything fancy. I use a fingernail file found at any convenience store. Super glue. Any kind will do. Note that thinner glue will be a little more difficult to work with but will dry faster. Black Sharpie (optional) Q-Tips. For applying the glue. Small piece of plastic, preferably a plastic bag. A towel for any emergency cleanup. NOTE: Work in an open area with good ventilation! Any water coming in contact with the glue will speed up the hardening process, but will also create a fume that will irritate your eyes and nose. It is suggested you let the carbon parts dry completely before applying the glue. Step 1: Remove your carbon fiber parts and, under running water, lightly sand the outside edges with your file. Make sure you sand BOTH sides of your parts. Graphite dust is extremely fine and, since its not good to breathe in, sanding under water will eliminate the dust. The object here is to remove the hard edge of the cut carbon fiber. Step 2: This step is completely optional, but I like to do this because if looks a little more Factory. Once you have sanded all the edges, take a Sharpie and color the edges of your carbon fiber parts. This will turn the edges black and make the final product much more appealing. If youre adventurous, you can try different color markers. I Sharpied a red one once and it came out pretty cool, but because it was initially a little hard to see, I had to do some additional prep work. DO NOT USE PAINT! If you use paint, the super glue will not be able to seal the edges. Any collisions will cause huge paint chunks will fall off (at the same time that your chassis de-laminates). Next, find yourself a place that you can set your parts to dry. Remember, you will be applying super glue to
  2. 2. Start by sanding the edges of your chassis the EDGES of your parts and then setting them aside. Find some place where they wont glue themselves to the surface you place them. Step 3: BE CAREFUL! Super glue is great for bonding things togetherincluding FINGERS! Take your piece of plastic to pour a small amount of super glue onto it. You dont want to put too much that it overflows on to your work area. The reason we use plastic is that its not porous; the glue will not seep in and dry out. Step 4: Take a Q-Tip and dab a little glue onto the edge of the part. You may need to dab quite a few times; just make sure you dont put too much. Apply a good coat all the way around your part. Set your part aside to dry (should only take a few seconds). Follow the same procedure for the rest of your parts. Step 5: Once dry, you are free to continue assembling your vehicle. It is suggested that you complete this procedure BEFORE you build your vehicle.
