Composite tape wrapping on wood joints

[Bill Corbin]

I am considering the feasibility of using carbon fiber tape to reinforce wood log column-log beam interfaces by wrapping the joint. The logs are approximately 16” in diameter and are an integral part of a building structure. i can supply pictures if it will help.

 

My questions are:

• Does this idea have merit as applied to wood surfaces? If so:
• What product would you suggest for the wrapping?
• What epoxy is recommended? Are there instructions for applying the epoxy?
• How can we calculate the strength of the wrapping? Are there strength tables?

Sorry for the delay. Looks like my response didn't get posted!

Pictures would help us better understand what you're trying to do! I'm not quite sure this is our area, but definitely willing to help if we can 🙂

Are you referring to where the two main beams join at the T?

[Bill Corbin]

Yes, we are thinking to X wrap the joints for strengthening purposes.

I don't think this would be the right application for this. It would probably trap moisture and bugs. Not to mention how you're going to cure it and protect it from UV long term.

Why not just use lags/bolts? Are there any other solutions out there? This seems pretty non-standard. But then again, I haven't built a log cabin in a while 😄
