I have a repair project on my bench.  Its a guitar that has a broken neck.

Repairing the guitar neck wasnt that hard, but I am considering reinforcing it somehow, and I thought about wrapping the neck in carbon fibre.

The big problem I have with this is the finishing it where the guitar neck meets the fretboard.  This guitar has a plastic binding around the fretboard like this....

As you can see, white plastic binding (it has those black dots on to mark the location along the neck) is glued alongside the fretboard, which is made of wood.  Most likely these are attached with CA/Superglue before finishing the guitar with Lacquer.

My problem is that if I wrap the neck in carbon fibre, I will need to secure it somehow, and the binding may make it difficult to but up against the edge of the .  I dont really know that much about the resin used to attach carbon fibre to a shape and if it wouldnt just come loose, especially because there will be some movement in the neck..


which brings me on to my second question.  Guitar necks move and the carbon fibre would need to move with it, so how strong is the resin to make the part solid?  Will it act as an adheisive?  is the idea of vibration and movement going to cause problems for carbon fibre?

Carbon fibre seems to be a material that guitar repairers and makers could use, and theres a lot of questions here I know, but I am keen on having a go at not only repairing a guitar with CF, but integrating it in future repair work, depending on how reliable it will be.  can anyone help?

Hi there, I see you like guitars and might be interested in composites so here is a cool video to start with Wink

To start this with, I do not know anything about guitars but have some experience with composites, so I'll share you my thoughts.

About your questions:

1. getting CF correctly on the guitar neck
    Use some composites adhesive to possition the dry carbonfiber onto the neck. then you can trim of the excess carbonfiber and add some resin on top of that.

    second thing you could do is add some epoxy resin on the neck (first tape of the parts that may not come into contact with resin) you let the resin go into a tacky state.
    when it feels a bit sticky (like post-its :p ) then you can put the carbonfiber on top and it will stay in its place. then you add some resin on top do some sanding and the job is done Wink

2. about the material. I can not really help you on that case because I dont know how a guitar behaves... CF will make it very stiff with epoxyresin. You could use an epoxyresin from easycomposites that has some flex. Maybe this might be better. You could also use a cheaper material called fiberglass, when resin is added it will become transparant so you will still see the wood. 

I know this is a lot of information, but keep in mind that not everything always goes as planned, when working with composites, you might need some practice first to be able to do this in a good (clean) way and not ruin you precious guitar Smile

Another idea for you take a mold of the neck and arm use wax sheets to give you Clarence ..1mil which is 4 layers 3k 200 gram then bond to guitar.giving you added strengh,it does mean making a mold but not a big job.

why not take the binding off around the edge. wrap it in cf and then use the ledge where the binding was as a guide where to trim the cf. you may have to use a bit thicker binding in the end though
