Characterizing the flow-cure behaviour of thermoset plastics using thermoanalytical and ultrasonic methods

  • The prospects of modern thermoanalytical methods for characterisation of flow, curing and final mechanical behaviour of moulding compounds were demonstrated. Using urea resin moulding compounds from different manufacturers the possibilities of the various techniques could be shown. With comparatively low effort, fundamental information can be gained before production process had been started. On this basis it is possible to make appropriate material selection at an early point in the process chain. On the basis of thermoanalytical data an incoming goods inspection can be established. Also it is easy to control the compliance with the conditions of delivery. In some cases it could also be helpful to have stored analysis data especially when problems appear in manufacturing process or unexpected part damages occur With the ultrasound measuring system it is possible to transfer the findings from the analytical methods directly to the processes in the mould.

The application of ultrasound provides Dynamic Mechanical Analysis in the mould. Beside quality assurance ultrasound can also be used for process optimisation, especially for reduction of cycle time. In an advanced form ultrasound information can be used as a basis for improved machine control based on material state. The ultrasound measuring system developed by ISK Iserlohn and BAM can be obtained from the ISK.zeige mehrzeige weniger
