Hi,

I managed to produce some small damage on my kite foil:

The damage was caused by the lines that got wrapped aroud the foil in wavey conditions. The damage appeared on the back side of the foil where the edge is very thin (1-2 mm). I am wondering how to fix this. Is seems that there is not enough space to use some extra fiber to reinforce the area. I found this epoxy repair filler. Will I be able to fill the damage using this or will the filler struggle to make a bond with the rest of the material due to the small area of contact? Do I need to use epoxy coating resin over the filler? Alternatively I found this repair resin. Would it be better to use this to fill the damage? Or is there any other approach that you would recommend?

Thank you. I will appreciate any help.

Hi,

The filler will bond just fine, it  will not make a repair as strong as the original material.  It is more suited to cracks and small chips rather than areas that are broken away. 

Realistically the best way to repair  that will be to scarf in new material.  If you taper the  edge of the damage when you sand it, you should be able to get a reasonable overlap with some carbon fibre patches meaning you get a good join and once cured, can sand it smooth.

Hi Warren! Thank you for your reply. I decided to try with the filler first and see how that performs. If that won't work I'll have to go with the patch.
