Microhardness measurements in thermoplastics


Polimery 1982, No 11, 440



DOI: dx.doi.org/10.14314/polimery.1982.440

Summary

The significance and possibility of measurement of the microhardness of thermoplastic materials has been discus­sed. Basing on the definition of hardness, the methods of measurement and testing procedures have been reviewed and analyzed. The effect of the indentation deformation after removal of the indenter on the results obtained has been evaluated. Basing on the literature data and own re­sults it has been found that it is reasonable to measure the microhardness of thermoplastic materials with the use of microhardness-meters accessible in Poland. Many important uses of the analyzed measurements have also been indi­cated.
