Hi, I’m looking for some advice and guidance. I want to make a hollow egg shape out of carbon fibre. My idea is to use a balloon as a basis for creating the mould. My initial idea was to first coat the balloon in paper mache clay (paper, PVA and gypsum ) to create a hard egg shape and then cover that with fibre glass to reinforce it. A better alternative would be use a product called StyroSpray 1000 instead of the paper mache clay as I think it would produce a smoother inner surface. I would then create a 2 part mould by cutting the egg into 2 symmetrical halves and applying gel coat to the inner surfaces. I could then lay carbon fibre into the 2 halves separately and subsequently join the the 2 halves with epoxy. I’d welcome any comments on this proposed method. Is there a better way of doing it? Would I be better using the hard egg shape created by the StyroSpray to create a silicone mould for example? All comments and guidance welcomed.
