Fibre- and particle-reinforced Al-MMC structures

JEC Americas 2012 - CPS Technologies manufactures metal-matrix composites (MMC) comprised of an Al-matrix filled with hollow ceramic spheres to create structures that weigh 40% less than aluminium.

In combination with integral strong fibre-reinforced skins, these are ideally suited for structural components requiring reduced weight and increased stiffness.

Floor decking, crush zones, decreased NVH (noise, vibration and harshness) in aircraft and automobiles, along with enhanced blast protection from IEDs (improvised explosion devices) in military vehicles are produced by varying the combinations of fibre- and bubble-filled MMC.


The ceramic-fibre reinforced aluminium foil demonstrates remarkable fire resistance. A one-half mm thick (thin!) Al-MMC sheet resisted the direct impingement of a propane torch for at least five minutes. This compares with 30 seconds to burn through a plain aluminium sheet of the same thickness. This material has the toughness and resistance to abrasion of metal and could be used in automotive or aircraft firewalls, fire-resistant access panels or doors, or in enclosures to protect critical equipment (or people).


Tubes made with ceramic fibre-reinforced aluminium sheetstock can be rolled and riveted to make lightweight, stiff structures. These tubes have exhibited excellent heat resistance and heat shielding properties.
