摘要：

A methodology was developed to analyze quantitatively the morphological aspects of sliding surfaces resulting from the variation of sliding velocities in the following polymeric composites: polyamide 66 with 30% of glass fiber reinforcement (PA66GF30) and polyamide 66 filled with MoS2, (PA66+MoS2). The approach was based on techniques of digital image processing obtained by optical microscopy. The results showed that for these conditions, the increase in sliding velocity improves the friction performance of PA66GF30, since it promotes the development of a surface rich in glass fibers and cluster glass fiber fragments homogeneously distributed over the material.
