Carbon Kevlar T750 Hull

[Mini GT]

Folk need some advise

Planning to build a light weight T750 hull out of Carbon Kelvar to compensate for my weight.
Would like to hear from the experts your thoughts on the following:

• The suggested cloth layup for the hull
• The recommended hull thickness
• Pros and cons
• An other concerns or suggestions

Thanks

Not sure what the name of the material is but racing kayaks are built using an interwoven carbon/kevlar and one layer is quite strong. I would think two layers with a thin core, vaccum bagged with some stringers of the same material all vaccum bagged would be very rigid and light. For the transom I would use a honeycomb sandwich panel... or multiple panels laminated together. Flat pressure bulkhead panels in airplanes are light but enormously strong. They are carbon honeycomb panels.

I'm in the same learning process.
For my particular project it's vacuum infusing but I've often wondered how I'd make a composite core hull.
Initially I thought that probably best to build a foam sheet hull over frames and epoxy glass that.
Then turn it over and do the inside.
That's a totally wet manual lay up
But now that I'm studying infusion methods, I'd probably go that way.
From building / repairing other hulls I leaned that strakes should be attached afterwards.
That is, build the hull, then glue and screw the strakes on.
I have a system of doing this where the edges of the strakes can easily be made razor sharp without using filler.
I don't use polyester for anything structural, all epoxy and also Vynle, however it's spelt.
For years I only used a brush to work the composite but now I use a brush and a roller.
Rollers really get the resins moving.
