Metal matrix composites (MMC) are materials that combine a metal matrix with ceramic reinforcements in the form of fibres, particles or flakes. The material may then be used in manufacturing components, for example by casting. The project MACS has been focusing on the understanding of cast aluminium reinforced by silicon carbide particles and its weaknesses, as well as investigating parameters for machining since the particles make machining difficult.
Aluminium as a material has an amazing potential, but we only use a fraction of this. Reinforced aluminium has been dragging due to high production costs combined with a knowledge gap between the fundamental research and the applied industrial research. The majority of the research on MMC shows fundamental research based on laboratory studies.
This project was intended to turn fundamental research into applied research in developing and manufacturing demonstrators in industrial environment. In that way unique competitive advantages are created for Swedish industry by the ability of faster development and manufacturing of advanced components with multifunctional properties, which creates lighter Products.
The purpose was also to strengthen and develop Swedish subcontractor industry by building unique competence regarding development and manufacturing of MMC material, and future needs of functional and sustainable components. Within the projects work has been done within permanent mould casting, cast forging, simulations, machining and rheo casting.
We have been able to show a possible weight reduction of 60% by switching from steel to aluminium.
