| 摘 要： | 利用动态力学分析仪和微型材料实验机分别对3种医用外固定型低温热塑性聚合物树脂材料A、B和C进行温度扫描和室温、不同应变率下的单轴拉伸实验,对比分析了3种材料力学性能的差异。研究表明:3种材料的玻璃化转变温度均在65℃左右,但材料C具有更宽的成型温度范围;3种材料的拉伸性能均体现出不同程度的率相关性,材料C具有更好的塑性。

| Abstract: | Temperature scanning tests and uniaxial tensile tests at room temperature under different strain rates for three kinds of existing low-temperature outside fixed thermoplastic medical polymer resin materials (A, B and C) were conducted on dynamic mechanical analyzer and micro material testing machine to contrast their mechanical properties. It is shown that the glass transition temperatures of these three materials are all around 65 degrees C, but material C has the widest range of shaping temperature. Stress-strain responses of the three materials are rate-dependent and material C shows better plasticity. |
