A Test System for Dynamic Mechanical Thermal Analysis of Composites and Lightweight Metallic Alloys

运输行业对提高车辆燃油经济性、性能和减少二氧化碳排放的需求不断增长，推动了对轻质复合材料和有色金属材料在各种工程产品和创新技术中的应用的重大研究。虽然这些材料提供的重量减轻是非常有益的，但这些材料的工业接受需要准确预测使用中的机械性能、缺陷和微观结构特征。此外，了解新材料对先进加工技术或环境条件的反应（例如，湿度、腐蚀性环境）将使制造商能够保持产品质量并减少不良的环境影响。近年来，复合材料和轻金属也被纳入新型混合材料系统。例如，纤维增强聚合物复合材料已被用作结构混凝土中的增强材料。

The ever increasing desire of the transportation industries for improved vehicle fuel economy, performance, and reduced CO2 emissions, drives significant research into the use of light-weight composites and non-ferrous materials in diverse engineered products and innovative technologies. Although the weight savings provided by these materials are of great benefit, industrial acceptance of these materials requires accurate prediction of the in-service mechanical properties, defects and microstructural characteristics. In addition, understanding the response of the novel materials to advanced processing technologies or ambient conditions (e.g., humidity, corrosive environment) will enable manufacturers maintain product quality and reduce undesirable environmental impact. In recent years, composites and lightweight metals have also been incorporated into novel hybrid material systems. For example, fiber-reinforced polymer composites have been utilized as reinforcement in structural concrete.
