Abstract

Heated fuser roll subsystems commonly employed in xerographic systems are frequently assembled with endcaps which are inserted into precision manufactured, cylindrical cores. Various materials have been used to produce the endcaps, including: aluminum; stainless steels; carbon steels; and high performance plastics. Unfortunately, each of these materials has its disadvantages. Aluminum wears too quickly, stainless steel is expensive, carbon steels tend to rust or corrode while both steels are heavy, and high performance plastics often cannot be reclaimed for reuse.

Heated fuser roll subsystems commonly employed in xerographic systems are frequently assembled with endcaps which are inserted into precision manufactured, cylindrical cores. Various materials have been used to produce the endcaps, including: aluminum; stainless steels; carbon steels; and high performance plastics. Unfortunately, each of these materials has its disadvantages. Aluminum wears too quickly, stainless steel is expensive, carbon steels tend to rust or corrode while both steels are heavy, and high performance plastics often cannot be reclaimed for reuse.

The present disclosure is directed to the use of a metal matrix composite material, preferably aluminum based, that can be die cast or orbitally forged into a near net-shape, requiring little or no additional machining. More importantly, such a material is lighter than steel, does not corrode, and wears well so as to make it reclaimable for reuse. Al/Al2O3 and Al/SiC are candidates for the metal matrix composite materials, however, the specific composite materials selected may vary depending upon further considerations such as weldability, machinability, etc. It is also believed that the die cast or orbitally forged composite materials exhibit thermal isolation properties which may be of particular advantage when used in heated fuser r...
