Dynamic Mechanical Analysis and Differential Scanning Calorimetry for Measuring Structural and Mechanical Proper- ties, and Phase Transitions in Metals, Polymers & Cerami

这个项目将把聚合物、陶瓷和复合材料的研究纳入现有的实验室。这种设备的增加使所有主要类别的材料的结构和机械性能之间的比较成为可能。差示扫描量热计（DSC）是一种灵敏、定量的方法，可用于检测金属和聚合物的相变，以及聚合物的玻璃化温度和结晶性。现有拉伸测试设备的补充附件将允许陶瓷和聚合物的弯曲测试。为了充分表征聚合物随温度和时间变化的载荷，将使用动态机械分析仪（DMA）。通过在这些实验中加入计算机控制，学生们接触到现代实验室数据采集，并从繁琐的数据收集中解脱出来，使他们能够集中精力解释结果和发展分析技能。

This project will incorporate the study of polymers, ceramics, and composites into the existing laboratory. The addition of this equipment makes comparisons between the structural and mechanical properties of all major classes of materials possible. With a differential scanning calorimeter (DSC), a sensitive and quantitative method becomes available for detecting phase transformations in metals and polymers, and lass gransition emperatures and crystillinity in polymers. Supplemental accessories for the existing tensile testing equipment will permit flexural testing of ceramics and polymers. For the adequate characterization of polymers with changes in temperature and time dependent loading, a dynamic mechanical analyzer (DMA) will be used. By including computer control in these experiments, the students are exposed to modern laboratory data acquaition and are relieved from tedious data collection which allows them to concentrate on interpretation of the results and the development of analytical skills.
