热固性材料由于其塑性差、弹性变形低、材料损伤破坏过程中信号比较明显。而热塑性材料可塑性强、弹性变形相当较高。声发射信号的发生有着与热固性材料的很大差异。
With the characteristics of poor plasticity and lower elastic deformation , thermosetting materials can produce marked signals in the process of damage , however that of thermoplastic materials are different evidently because of theirs better plasticity and higher elastic deformation .
