| Abstract: | The meaning of the glass transition temperature(Tg) and its main testing methods were briefly introduced.Tg value of the PPO/EP composites was measured by using the DSC method and DMA method,respectively,and the differences between the two test methods were discussed.The results show that: the different test method has different test conditions,different test precision and different influence factors for testing results.As a results,the testing methods and testing conditions must be specified when Tg value for a certain material is given. |
| Keywords: | Glass transition temperature Polyphenylene oxide Epoxy resin Testing method |
