Investigation of wear behavior of PA 12 matrix ceramic reinforced composites produced by selective laser sintering method

Abstract

In this study, ceramic-reinforced PA 12 matrix composite materials were produced using Selective Laser Sintering (SLS), one of the additive manufacturing methods, and the wear behaviour of composite materials was investigated. Two different energy density values were used in the production of composite materials with SLS. Dry wear tests were applied to the produced composite materials. Wear tests were carried out at 25 mm/sec and 100 mm/sec velocity values and at 5 N and 20 N wear load values. As the wear test load increased, the wear rate increased, and it was determined that the increase in the energy density value in the production of composite materials adversely affected the wear properties.
