I am starting to build tube to tube road bike as hobby project. My question is “How to create joins between tubes correctly?”.
I will mitter tubes and glue them together with 3M DP420 (epoxy structural adhesive).
Next it is important to strengthen joints by putting some layers of carbon sheets.
Could someone recommend layers and orientations of layup of carbon sheets in joints?
Somewhere I have read that the overlap must be 1.5 times the diameter of the pipe.
A lot of people use prepreg with vacuum bagging together with high temperature for better strenghts. But I would like do not go by way of high temperature. Wet layup with vaccum bagging is for me as hobbiest more cheap method.
A lot of questins, I know:) Thanks
