Impact tests on filled and unfilled thermotropic liquid crystalline polymer injection mouldings

Polymer Bulletin Aims and scope Submit manuscript

Summary

Charpy and falling weight impact tests have been carried out on filled and unfilled thermotropic liquid crystalline mouldings between room temperature and 140 °C. There is progressive embrittlement on filler addition in both types of test, and a maximum in absorbed energy as a function of temperature is observed, corresponding to the glass transition temperature near 100 °C.
