Wishing to obtain information on the title subject joining tubular members. As I am designing a semi scale model of a microlight aircraft with partly open airframe structure, similar to a warren girder framework using approx. 10mm tube. I am seeking information on load bearing joining material for carbon tubes. The information I have obtained recently is from a U.S.A. Patent by Kryzysztof Kotlinski for F1 Car Frames and Aerospace frames. The binding material used is described as anisotropical binding wire. Is  anyone familiar or used such a method.
