Combinative Effect of Nanoparticles and Short Carbon Fibers

2 Combinative Effect of Nanoparticles and Short Carbon Fibers 

It is generally accepted that the overall behavior of multiphase materials can be considered as a function of the respective contribution of each phase, which is also true with regard to the wear properties. However, some special reactions were observed, which dominate the wear performance of polymer composites. In order to 

To evaluate the wear behavior of materials under different sliding conditions, i.e various contact pressures and sliding speeds, the time-related depth wear rate, W, was introduced 

Investigations on the worn surfaces were performed using a scanning electron and an atomic force (AFM) microscope. It is believed that SCF are 

The combination of nanoparticles and short carbon fibers exhibited a clear improvement in the wear resistance of both thermosetting and thermoplastic composites. In addition, this concept allowed the use of these materials under more severe wear conditions, such as higher normal pressures and sliding velocities. A topographic smoothening and a possible rolling effect due to the nanoparticles are supposed to be the reasons for this progress in the friction and wear performance.
