I completed the layup for the first side of the seat back bulkhead. The seatback is structural in the fuselage so it is basically like any other bulkhead except that it sits at near 45% in the aircraft. This means that the upper and lower edges need to be tapered. The edges also need to be floxed to made for a strong joint. Flox is simply cotton fibre mixed with epoxy. It is then sanded to make for a solid surface to mate the opposite fibreglass.
