Bonding Carbon Fiber Tube To Aluminum

What is the difference between the twill carbon fiber tubes and the ud carbon fiber tubes.

Bonding carbon fiber tube to aluminum.

The simple answer just the exterior ply of material. With the ability to bond dissimilar multi materials including aluminum and carbon fiber composites you can use lighter and thinner materials for groundbreaking innovations in form and function. The easiest way to envision a tube cluster is to simply look at a typical tube frame welded up from aluminum steel or chrome moly tubing. Another quick vacuum and acetone wipe down to remove any remaining dust oil and waxes.

Equally important was prepping the aluminum with the same steps. This tubing is designed for large applications such as telescope projects or light weight drums. Make sure that the component slides in straight and is not cocked off center. The aluminum plate sees a fair amount of shock due to the application.

In the case of bonding in tubing ends most of the mechanical load will be in directions where the tubing itself will carry most of the load. A quick vacuum followed by more sanding in a few areas that where missed. It is the only adhesive i tried that glues alu alloy to same for applications like a tube telescoped into a tube or a rod telescoped into a tube. Next up was abrading the carbon fiber with 180 grit sandpaper to add tooth for the epoxy to key into.

The seperation occurs between both the aluminum plate and the adhesive and the adhesive and carbon fiber. Unless noted on a specific product all of our carbon fiber tubing is made with ud prepreg on the inside and then will have either the ud exterior ply or a fabric ply. Only a small amount of force is required to fully seat the tube. I am having issues bonding an aluminum plate to a carbon fiber structure.

Now imagine simply cutting off all of the tubes leaving about an inch or two after the welds. First suggested here in response to an op from me several years ago. Begin pressing the aluminum bondable component into the carbon fiber tube. Joining carbon fiber tubes requires the use of what are known as tube clusters.

Recent advances in multi material adhesives have given manufacturers new assembly options beyond traditional mechanical and thermal assembly methods. Our large diameter carbon fiber tubes are comprised of rolled bi directional woven carbon fiber. It is a 2 x3 aluminum plate bonded inside a carbon fiber square.
