Abstract: The invention relates to a frame (2) including at least one part that is intended to support a skin (3) for receiving a part made from a composite material to be polymerized in an autoclave, said skin (3) defining the general shape of said part. The frame (2) is characterized in that it is a single-piece foundry piece.
Abstract: This spheroidal graphite or flake graphite cast-iron alloy in weight % comprises the following elements: Carbon (C) between 1.2% and 3.5%, Silicon (Si) between 1.0% or 1.2% and 3%, Nickel (Ni) between 26% and 31%, Cobalt (Co) between 15% and 20%, the remainder being Iron and inevitable impurities. Application to the production of tooling.

Abstract: A spheroidal graphite cast iron alloy comprises, in % by weight, in addition to addition elements, the following elements: Ni between 3.5% and 7%, Cu between 0.5% and 3%, Mo between 0.15% and 1%, the remainder being iron and inevitable impurities. The spheroidal graphite cast iron alloy may be used in manufacturing a part such as cogwheels and gear rims. The method of manufacturing the part may comprise casting a rough casting blank, notably into a mold, and letting the rough casting blank cool in the mold, thus obtaining the part.
