TRUE COMPOSITES Carbon Fiber Sheet & Epoxy Resin Kit (36 x 6 + 8oz of Epoxy) 2x2 Twill, 3K, 5.7 oz. - Carbon Fiber Fabric, Carbon Fiber Repair Kit, Kit de Lámina de Fibra de Carbono y Resina Epoxi

Another victim of the epoxy not setting up and hardening after seven days. I followed their mixing instructions exactly. I’ve been mixing up epoxy for various projects for many years and have never had a problem like this. Ruined my project and left me with a huge, sticky mess. Carbon fabric seemed fine but I’ll never truly know. If you must try this product despite many of us have this same experience, please test it first on something that will be discarded anyway.

The resin is bad. It won’t harder. I mixed it 1 to one and left it indoors. It’s been 2 days and it’s still wet. Received a replacement and have the same problem. This time I went heavy on the hardener and placed the piece in the oven at 170F. 2 days late and it’s still wet. Absolutely garbage. What a waste of time.

Good

Quality and ease-of-use

I would like a little more details in how much epoxy to mix for a smaller repair.

decent kit for small to medium carbon fiber repairs. instructions provide enough detail to use. will be used on CF racing fuel tank, seems like will work just fine.

This is my first attempt to work with carbon fiber. I broke my bike frame (I fell of a trainer... Long story) so my frame was cracked (sounds like when you are bending wood). After some research, I found that my frame was repairable, but it was expensive ($500 to $800 quotes). After daydreaming with a new bike, I felt like I should give it a try and repair the frame. I love my bike (Fuji SST 1.3) so, I set aside time and begin to sand the area, to discover there was a hole in the frame (see picture), and a crack around the entire tube. Did some research on how to repair the frame, got me some sanding papers (get the 3m 80 if you want to speed up the process) and begin my journey. Word of advice, get some single blade or an Xacto blade-like, scissors are a bad idea as this carbon sheet its very flimsy. I mixed the hardener and resin equally or 1 to 1 (It was a guesstimate). With a 1.5 brush, I start applying the epoxy and 10 minutes later I glue the carbon sheet (keep mixing the expoxy or it will bee to hard), gave it a second top coat and with a plastic bag, I squeeze it all the air and tape the bag very tightly and leave it 24 hours (air-conditioned indoor). Next morning, I unwrapped the repair (see picture of a very corrugated repair) and with an 80 grain, started sanding all that. Then with a 240 started smooth things out until I got rid of the rough edges and it was smooth. Finished up with an 800 (or could be 600) and gave it a light epoxy coat with a 1.5 brush (do not reuse the brush) and there you have it. With less than $50 I repaired a frame that looks good and will serve me well for years to come.

I used the product to repair a carbon fiber holster that was cracked.

Im using this kit for my first attempt at carbon fiber. With that in mind, my project went into the trash but it was not the fault of the kit. The epoxy resin worked great and the material was fine.
