The fuse sides are made with 4mm balsa partially covered by 160g/m2 carbon fabric + epoxy. A glass plate is waxed and coated vith PVA. The two pieces of carbon fabric are imbibed with epoxy and are placed on the plate. Then, the balsa is compressed on the fabric during the epoxy curing.
Very interesting, and good work. One thing I have noticed is that when making flat panels, as you are doing here, the PVA is not always needed if you are laying up an a really smooth surface. I have not tried glass, but have done this with 3mil mylar sheet stretched over a smooth surface, and it does not even need waxing. The mylar sheet peels right off.
