Marine composite propellers often refer to ship propellers, usually made from fiber composites like glass or carbon fibers infused with a high-strength resin like epoxy or polyimide. These kinds of composites made are strong, light and high-tech materials. Such composite propellers can be produced in several ways, including vacuum infused molding and injection molding process, depending on size and resin viscocity.
