|CPS Technologies’ unique processes can make Net-Shape, structural, metal matrix composite (MMC) parts with either silicon-carbide (SiC) particles or continuous ceramic fibers as the reinforcement. SiC particle reinforced aluminum (AlSiC) has the stiffness of cast iron and the weight of aluminum, and continuous fiber reinforced aluminum has the strength and stiffness of high strength steel at less than half the weight.
Applications range from pushrods for racing engines to attach plates for high speed robots. If your application has demanding requirements for high stiffness or strength, at minimum weight, you should consider MMC. It can be precision cast to near net shape, and can include threaded inserts of aluminum, steel or titanium, for attachments.
MMC Structural Composite Data Sheet
|Typical Particle Reinforced Aluminum||Typical Fiber Reinforced Aluminum|
|FTU||0.3 GPa (45 ksi)||1.2 -1.5 GPa (180-220 ksi)|
|FCU||0.3 GPa (45 ksi)||1.7 -3.4 GPa (250-500 ksi)|
|E||170 GPa (26 msi)||240 GPa (35 msi)|
The process for producing either discontinuous, particle reinforced or continuous fiber reinforced part starts with a preform that has the shape of the final part. The preform is then infiltrated with aluminum to produce a metal matrix composite component. This process is similar to the polymer composite process called resin transfer molding, except the preform is infiltrated with molten aluminum rather than resin.
CPS Technologies has been the leading producer of metal matrix composites for thermal management of electronics for over twenty years and has produced millions of LIDS, IGBT’s and other specialized components which combine our unique Quickset™ performing capability (Silicon-Carbide particulate performs) with our casting processes. We have now expanded that capability by demonstrating components for mechanical, structural and armor applications. Shown below are a few examples. Our current equipment capabilities allow us to process parts that will fit in an envelope of 17 x 32 inches (80 x 40 cm).
