Wear damage of carbon-polyethylenimine composite

Wear resistant composite offer reliability and value in a wide range of wear-sensitive applications. These specialty compounds give designers and processors tremendous flexibility and significant benefits over composite. After wear, the composite's roughness as brass counterface increases. At low loads, polyethylenimine layer gets removed. At higher loads, some of the fibers have cracked and the gap is occupied by brass debris. Brass powders are accumulated in some portions on the composite surface. The debris contains brass fragments, carbon fiber fragments as well as polyethylenimine material. At high loads some of these debris gets compacted between the fibers.
