I split the wing into 4 pieces for easy printing. Scaled to 50% for rear wing.
I'm as far as most of the cladding for the front wing, I need to fair the front wing and then infuse a couple of sheets of glass surface tissue for final impact protection and sealing of kevlar strands over front and rear wing.
I botched the rear wing resin infusion, forgot the peel ply layer between the infusion meshes and the fabric sheathed 3D print. However I managed to peel off the infusion mesh at the perfect time, lots of sanding and ready to go again, with most of the strength of the composites
The front wing has a layer of Kevlar inside, a strip of 200 wide 600 gsm uni glass wingtip to wingtip on the top only, a layer of carbon/kevlar cloth over that and then I added some kevlar and CF/kevlar, basalt patches around the middle top before a basalt sheet over the entire top. After a couple of days to cure it I can bounce on the top quite safely with the tips pressed into the carpet. The 2 bottom layers are in tension and the top multiple layers are in compression under normal use. I wanted to use basalt for the uni but my only source I can find so far that looks promising is 100 meter x 100mm wide unidirectional basalt rolls. The 600gsm uni leaves a ridge that needs a lot of fairing to blend in.
I've carved an 800mm fuselage from pine and planning to heatshrink more unidirectional glass fibre areound it, sandwiched between some cloth layers. I bought a naish 5.3 wing and I'm currently debating a Gong HIPE inflateable or an Indianna Wingfoil inflateable for my board. I have an 820mm mast with base on order from aliexpress from a couple of weeks ago, hoping my kiteboarding and windsurfing skills will translate to getting up on foil with the long starter mast
