Plastic machine parts of small airplane

Our daily life is strongly connected to the modern materials e.g. polymers and composites. These materials play more and more important role in airplane and aviation technologies. Not only the common places but load-carrying machine elements are produced of light-weight and wear resistant plastics as well. In the aviation the machine reliability especially is important, so, the good friction and wear properties together with increased corrosion resistance and vibration damping ability, as well low mass features are essential. There are many sorts of technical polymers available of which sliding and load-carrying elements can be produced. To choose proper polymers for a given tribological application is not a simple task owing to many different parameters influencing the performance of a polymer sliding element
