  • When considering polymeric materials for the components design, their behaviour under external actions (mechanical, temperature, time, etc.) must be known. Thus, the study of their mechanical properties is essential if these materials are going to use as structural elements. The traditional mechanical tests, as tensile test or dynamic mechanical analysis (DMA), are widely used to determining the mechanical properties of bulk polymers or films. However, when these materials are used as coatings or when the available component volume is limited, the traditional tests are not suitable to determining the mechanical behaviour. Depth sensing indentation test is a technique that allows obtaining the mechanical properties of a component, at surface level, even for very small samples. In this work the possibility of using depth sensing indentation technique to characterize amorphous polymers was explore. The results were compared with those obtained by DMA.
