I'm making some carbon stock for my next guitar(s). Too fiddly to make small parts so making stock for 2 guitars at a time. This is basically a very very high strength wood, kinda, it's about 67% UD along 0, and some UD covering -45/+45 and 90. The stack is about 17000gsm and it infused to about 17-18mm thickness. Seem I achieved around 50-53% fiber content based on my estimates but haven't weighed the part with precision. Will mill it flat and rectangular and will know then. But considering the loads in this part, even with a lower F/R ratio and some voids, it is way overkill for it's function. It will have some pockets milled in so I'll have a chance to see if there are voids, on the outside it seems well wetted through even at the bottom. This was actually my first infusion job and quite a chunky stack, the resin gelled and stopped traveling through after about 2.5hrs so I had some emergency inlets made. Post cured to approx 60deg for 4 hrs, but I doubt that made much of a difference, and quite unnecessary for this particular part anyway. Next infusion job is a 13mm stack for the necks. I'd like to have a very stiff neck to improve sustain and note stability, been modelling various configurations and materials in Fusion360 and the carbon necks should be a mile stiffer than any wood neck, but that's just theory for now. One guitar will be a bridge pickup only, for chugging, the other one don't know yet. Overall happy with the infusion but next time I infuse something so thick I'll know how to plan better.
