hello,
i have a crack in my handlebar, 
the crack is about 90% round the bar on the rounded  curve,
the handlebar is made from a carbon/kevlar material,
after watching the video on the fishing pole repair i have a few questions please?

q1 my repare needs to be strong enought to take abit of weight no more then at most 50 kg half my weight but not for long periods of time, so would about 3 layers of fiber do it?

q2 in regards to layers i was thinking carbon kavlar carbon mix.

q3 when applying the layers do i need to let each layer fully cure/dry b4 applying the next layer,

the finsh is not important has the bar is covered in bar tape.

I have repaired lots of tubes with yachts masts, booms and bicycles frames.

If the break is in a straight enough section of the tube then best to glue in an internal sleeve tube and let this set in the right way/shape. Then grind an appropriate area away removing the broken bits and creating a taper, then do your external laminate so the finished tube section is now smooth to look at but is probably twice as thick and much stronger than the original tube.

Since it is 90% broken you should just cut it through to start fresh.

The laminate you add can then be wrapped with a 20mm wide strip of peel ply to compress and smooth things out. Remove when cured and sand to shape further, finish with a resin coat or paint.

And a final tip is don't use any Kevlar as this will be easier to do and deal with.
