Fatigue Behaviour of Polymer Nanocomposites—A Review

Abstract

Most of the household articles and devices which we use in everyday life are made of natural polymers and synthetic polymers. Existing research also reports that polymer nanocomposites show far better performance versus micro-fillers. Premature failure, of the machine components, occurs well within the endurance limit of the material. This failure due to fatigue is a common phenomenon on many of the applications across industries and hence the prediction and prevention of fatigue failures is critical for safe and economic operation of machines. This work reviews various methods of fatigue characterization of polymer composites. Stress–life and strain–life approaches have been applied by many researchers in this domain. The fatigue characterization leads to the development of life estimation curves by both these methods. There are also works done on other methods to arrive at Stress–life curves. This paper addresses these different methods of characterization and compares them. The analysis of these data for evaluation of various fatigue parameters is also covered in this work.
