Several disks will be tested and compared to each other to determine the best polymer. This is a side view of the actual prototype built by Polytech and Atotech. To save money, many of the materials used in this prototype are found in the Atotech fabrication plants. As shown on the right, the wear on these polypropolene disks after about 24 hours of use. The plastic flakes off causing wear.
Different polymers possess different properties in wear.
A computer driven LVDT will be used to accurately plot wear in time intervals.
