Hello,

I'm making my own carbon fibre frame and iI want to bond the tubes together like the below image.
what type of adhesive do you recommend? 

thx!

For Structural applications like that, I would recommend our ET515 Semi Flexible 15min Professional Epoxy Adhesive due to its high flexural strength under shock and vibration. 

However, I would NOT recommend a simple butt and fillet joint like in the picture.  You would definitely want a larger surface area and also overlapping fibres or material for strength.  You could wrap the joints with carbon tape or have inserts bonded across the join to strengthen the join.
