Design of Multi-functional and Smart Composites

本计画之“多功能复合材料之调和设计”分为以下几个课题：（1）高性能与新型功能金属基感测/致动器材料元件之开发;（2）多层结构薄膜材料之设计与开发;（3）新型活性复合材料之设计与开发;（4）材料特性分析。非破坏性评估，以实现更有效的材料开发流程。2002年是本项目的最后一年，我通过总结每个成员的研究结果提出了一个重要的观点。主要研究结果如下：1）研制了用于生产传感器/致动器材料元件的快速凝固熔体旋涂设备（单辊和双辊法）。极细（直径; 0.03-0.1mm）和薄箔（厚度：20-200 μm，长度：1- 200 cm，宽度：1- 20 mm）试样，其强度、塑性和性能均有所提高 关于我们 通过控制非常细的柱状晶粒的微结构成功地制造。(2)研制了相变温度为-20 ~1260 ℃的TiNiPd、NiAlMn、RuTa、RuNb系热弹性形状记忆合金和线性驱动TiNiCo合金。此外，还开发了新型铁磁SMA、FePd、FePt和新型磁弹性磁致伸缩FeGa合金，并在2002年秋季东北分支会议上获得了JIM Poster演示会的奖励。(3)采用MOCVD方法制备了多层氧传感器材料，制作了电极膜/离子导电膜/电极膜/PZT/电极膜结构的器件。(4)“智能复合板”，其在聚合物基质中具有铁磁SMA填料。它能够检测内部损伤以及抑制受损功能的形状恢复效果。此外，与韩国研究小组合作，开发了热弹性形状记忆TiNi纤维增强/Al合金基体，并通过改进的有限元分析模拟和预测了其机械强度和变形行为。因此，我认为我几乎达到了一个目标，并展示了该项目最后一年的结果，并概括了上述研究课题。少

In this project, "Harmonic design of multi-functional composites" is divided in the following subjects,]i.e. (1) Development of high performance and new functional metal-based sensor/actuator material elements, (2) Design and development of multi-layered structure thin film materials, (3)Design and development of new active composites and these (4) materials characteristic analysis, non-destructive evaluation for more effective material development processes. A t his year degree (2002) was the last year of this project, and I put an important point by generalization of the research results from each member. The main results are concluded as follows.1) The originally designed, rapid-solidification melt-spinning machines (single and twin roll method) for producing the sensor/actuator material elements was developed. The very fine (diameter ; 0.03-0.1mm) and thin foil (thickness : 20-200 μm, length : 1-200cm, width : 1-20mm) samples with improved strength, ductility and performances were … More successfully manufactured by controlling microstructures of very fine columnar grains.(2) Thermoelasticv shape memory alloys (SMAs) of TiNiPd, NiAlMn, RuTa, RuNb system alloys which hadf their phase transformation temperature from-20 to 1260℃, and linearly actuation TiNiCo alloy was developed. In addition, new type of ferromagnetic SMAs, FePd, FePt, and new magneto-elastic magnetostrictive FeGa alloy also developed, which was awarded by JIM Poster presentation session in 2002 Fall meeting in Tohoku branch.(3) Multi-layered sensor material for sensing oxygen that was made by MO-CVD method to fabricate the device of electrode film/ion conduction film/electrode film/PZT/electrode film structures.(4)"Smart Composite Board" which has ferromagnetic SMA fillers in the polymeric matrix. It enables to detect the internal damages as well as shape recover effect for suppressing the damaged function. Besides, thermoelastic shape memory TiNi fiber reinforced/Al alloy matrix was developed and the mechanical strength and deformation behavior can be simulated and predicted by modified FEM analysis by the cooperation with Korea r team.In consequence, I identified that I almost achieved an aim and showed the results to do as the last year of this project and generalized a study subjects as things mentioned above.
