Tubes Compatible With This Connector
DragonPlate End Connector Blanks have no thread and require machining. They include a centered mark, allowing you to drill and tap whatever thread size you need. For use with 0.5" ID tubing. Anodized aluminum.
One of the primary concerns when bonding metal fittings into carbon fiber tubes is the fact that the metal component, when subjected to reductions in temperature, will shrink much more than the carbon fiber tube. To eliminate this problem, our patent pending connector incorporates a slotted tubular design, which has a two-fold effect. First, the slots allow the aluminum to contract circumferentially without as much change in the nominal diameter of the insert. Secondly, the slots provide compliance to the part, which further alleviate peel stresses by prohibiting the aluminum part from imparting as much peel force on the adhesive layer. In addition, this design includes a ridged outer surface. This further strengthens the bond inside the carbon fiber tube by placing more epoxy in shear (and most structural epoxies are about 100 times stronger in shear than in peel).
This combination of form, function, and resistance to thermal delaminations makes our DragonPlate tube connectors a versatile and robust option for many projects. Each connector also comes with a foam plug to contain adhesive and enough bond line control micro glass beads to ensure a proper bond fit.
