I tried (10:1) and (5:1), the part still seems to be quite weak. I tested with the (5:1) ratio and the overall viscosity of the mixture seems low and I get air bubbles inside the part. The part is made up of 25 layers of glass fibres (Woven) so it's solid. Its a layering procedure only. The mixture also does not produce any heat when combined together. The part also does not pop out of the mould and it takes a lot of hammering to get it out which damages the upper surface. I used a lot of Honey wax mould release for this as this was the only one available. The mould is just a hollow cavity of a part and I tried to layer the fibres using a stainless steel base below it. The resin still spreads on the whole stainless steel base when everything is cured but pops out well without effort due to wax release. I am quite new to this but I think with your advice I would be able to find a proper solution and share it with all of you. Thanks. Tags Epoxy resin Fiberglass hardener Wax

It is not as simple to say resins containing x and y can use a ratio of b:c. The componants will likely be in different proportions and have different additives depending on the manufacturers blend.
