Abstract
The volumetric heating properties of microwaves make them an extremely useful tool in industrial applications for processing materials. One particular material that is experiencing an increase in microwave processing is plastic. Microwaves are being used increasingly more often for high temperature joining of thermoplastic materials. Unfortunately this method of welding creates a heat-affected zone (HAZ) due to the difficulties found in directing the microwave energy solely to the joint interface. Furthermore the material properties exhibited by this HAZ might differ greatly to those of the parent material in its original state.
A non-destructive technique, performed on the Ultra-micro indentation system, is carried out to evaluate the properties of the HAZ. From this test it was possible to obtain results that can be used to analyse the hardness of both heated and unheated material. These results were in turn compared with other destructive methods of analysis such as impact testing and tensile loading, and with another non-destructive test, photo-elastic analysis, to determine the accuracy and validity of the UMIS non-destructive test.
