Before you hit your work station, it is important to consider the tools needed, especially the adhesive. Make sure that it does not compromise or affect in anyway the temperature range of the application; chemical or even weather exposure. A room temperature curing maybe deemed safe to use. First step is to determine the exact measurements of the carbon fiber tubes to be trimmed and bonded. After the tubes were cut into the desired lengths and sizes, the insides of the tubes should be prepped first. This will allow the tubes not to stick to the mandrel while on the process of bonding. One way to do this is by sanding the inner part of the tube until the surface becomes smooth. Take note that applying too much pressure while sanding may inflict some scratches to the carbon fibers that may result into weakening of the entire tube. Try abrading with one stroke only. Once you produce black sanding dusts, then you are ready to clean the surface of the carbon fiber tubes. Your tubes should now be ready for the so-called water break test. This will ensure if there are no release chemical remains from the insides. If there are beading resulted from the test, then the tubes are still not free from the chemicals, hence, should repeat the procedure until the inner side is already chemical contamination-free. All parts of the tubes should be completely dry before taking the next step which in the degreasing part. Here, you need a significant amount of acetone applied in a cotton or paper towel. Degrease all parts of the tubes until all black dust cease to exist. Once every tube is clean, it is time to prepare the hardener and resin. Mixing these substances are not as complicated as it looks like. Once you produce your desired mix, then the last step is waiting for you the actual bonding! With the use of a short resin brush, apply a very thin layer of resin into the inner part of the tubes. Make sure to go back to the same areas to make sure that everything is covered. Do the same with the outer diameter of the carbon fiber tubes. Once done, slowly push the tube cap into the main part of the other tube until you reach your desired point. Slightly twist both tubes as you push them closer together. Wipe off excess resin with paper towel. Clean the remaining surface as well until the bonded tubes are clean and free from any resins. By following these simple steps and with a little perseverance and patience, voila! You have yourself a bonded carbon fiber tubes ready to use.
