I am new to the composite repair process but have been playing around with different products and repairs.

My present situation is that I have been trying to repair a composite hockey stick that has broken in the shaft. I have tried a couple of techniques with both being unsuccessful. I have tried the repair from the inside using a carbon fiber sleeve and resin. It holds up but definetly not strong enough for a game of hockey and eventually breaks where the repair was done.

I have also tried on the outside, which lasted longer, but it eventually broke where the repair occurred. I believe I am either using the wrong type of sleeve or I a missing something in trying to do the repair.

If someone has some expertise or suggestions of what to use it would be greatly appreciated. I know it can be done.

Thanks for your help

A picture would be good as it would help us to understand the depth of the damage and if it is merely a resin crack or more structural.

I’m confident we could supply you with materials and advice that would enable you to make your own hockey stick repair even if it was a structural problem.

There are some specialist techniques for certain aspects of hockey stick repair but in the main part the materials are very similar to other repair processes.

The resin to use would be our Rapid Repair Epoxy, it’s got a very high bond strength and a lot of flexural strength (good for taking impacts). The process you’ll be using mainly will be wet-lay and then binding the repair with shrink tape.

We don’t sell a hockey stick repair kit as such but the materials and products that will be of a lot of use to you are:

CarbonFibre Braided Sleeve (a type of tube/sleeve that can be slid over the stick).

EpoxyRapid Repair Resin (this is an extra high performance repair resin which bonds better and has more flexural strength).

CarbonFibre Unidirectional 250g (often used in hockey stick repairs).

CompositesHigh Shrink Tape (very useful for winding round the repair whilst the resin cures).

200g Plain Weave 3k Carbon Fibre (often used in repairs).

My suggestion would be to start with some resin, maybe an appropriate sized braid and also some  Unidirectional. I would paint resin onto the damaged area, position unidirectional material either side of the damaged area and then slide the braid over and stretch it tight. Wet the whole repair through with the epoxy and then bind it tight with the shrink tape.

Once the repair has cured, you can then sand and polish up the surface finish.

Hope this helps.

I've made a little tutorial a while ago on how you could fix that problem...
