Process of fabricating a cast foam product, a cast foam product, and an intermediate foam product

摘要

Disclosed is a process of fabricating a cast foam product, an intermediate foam product, and a cast foam product. The process includes positioning an expandable component and alloying particles within a die and injecting steam into the die and expanding the expandable component to form an expanded component. The expandable component includes one or more of polystyrene and polymethylmethacrylate. The intermediate foam product includes the alloying particles, the expandable component, and the steam. The cast foam product includes a distribution of the alloying particles and the expanded component, with the alloying particles being physically bound by the expanded component.
