Upgrade to Micro Raman Spectrometer

9622373舍德勒这笔研究设备补助金将被德雷塞尔大学材料工程系用来升级现有的微拉曼光谱仪(MRS)。升级后的MRS将用于目前关于石墨/环氧复合材料微观机械行为的项目，开发MRS以测量三维应力状态，并研究用于潜在假体应用的生物相容性骨植入材料的增韧。在理解界面现象方面取得突破的潜力是很有希望的。纤维复合材料的界面应力、应变和三维应力的测量能力对于理解纤维复合材料在载荷作用下破坏的微观机理具有重要意义。这些设备也将被其他对钻石薄膜感兴趣的调查人员使用。由于MRS是一种测量两相体系力学行为的独特技术，所获得的结果可以用于测试微观力学模型，这需要从该技术获得的数据来验证和改进。***

9622373 Schadler This Research Equipment Grant will be utilized by the Department of Materials Engineering at Drexel University to upgrade an existing Micro Raman Spectrometer (MRS). the upgraded MRS will be used for current projects on micromechanical behavior of graphite/epoxy composites, developing MRS to measure three dimensional states of stress and to study toughening of biocompatible bone implant materials for potential prosthesis applications. The potential for a breakthrough in understanding of interfacial phenomena is promising. The capability for measuring, interfacial stress, strain and three dimensional stress in fiber composites is important in understanding micromechanisms of failure of fiber composites under loading. The equipment will also be used by other investigators interested in diamond films. Because MRS is an unique technique for measuring the mechanical behavior of two phase systems the results obtained can used to test micromechanical models which require the data that can obtained from this technique for verification and refinement. ***
