NSF-CGP Science Fellowship Program: Advanced Composites for Concrete Structures

该奖项将支持宾夕法尼亚州立大学建筑工程系Antonio Nanni教授对日本进行为期六个月的长期访问。他将与东京三井建设公司技术研究所Kazuhisa Yahagi博士和野田东京科学大学土木工程系Masanori Tsuji教授进行合作研究项目。他们将研究纤维增强塑料（FPR）复合材料在混凝土结构中用作增强元件的领域。这将包括测试FRP增强混凝土构件的耐火性，以确保其符合现行标准，并且在暴露于火焰时不会过热或失去其杆的强度。此外，他们将研究由点燃的FRP材料产生的有毒产品的释放。他们将进一步研究热塑性树脂的替代品，以取代更常见的热固性树脂。这可以提供更好的耐腐蚀性和更强的排水能力。它还可以减少加工时间，提供更清洁的工作环境和无限的保质期。这项研究之后将编写教育材料，包括这种新建筑材料的特性和设计，用于教学目的。这项研究可能会导致在建筑施工中使用FRP，目前正在被建筑设计师认真考虑，因为它有可能改善制造和降低生产成本。Yahagi教授是一流的研究员，他的研究所最近获得了新的设备，包括防火罩和编织机，可以进行防火测试和制造FRP复合材料。日本建筑业在这项技术上比美国先进得多。美国这方面的专家南尼教授说，应该获得他在美国无法获得的有价值的信息。Tsuji教授在他的大学拜访了Nanni教授三个月，这次经历应该有助于他们制定课程课程，将研究成果和在建筑施工中使用FRP的新技术结合起来。由于这些研究人员以前的合作是成功的，预计这个项目的结果也将是富有成效的，并可能在全世界范围内使用

This award will support a six-month long-term visit to Japan by Professor Antonio Nanni, Department of Architectural Engineering at the Pennsylvania State University. He will be undertaking a cooperative research project with Dr. Kazuhisa Yahagi, Technical Research Institute, Mitsui Construction Company in Tokyo and Professor Masanori Tsuji, Department of Civil Engineering, Science University of Tokyo in Noda. They will be researching the area of fiber-reinforced-plastic (FPR) composites for use as reinforcing elements in concrete structures. This will involve testing the fire-resistance of FRP reinforced concrete members to be sure it holds up to currently established standards and does not overheat or lose strengtrh in its rods when exposed to flaming fire. In addition, they will be studying the release of toxic products resulting from ignited FRP materials. They will further research the substitution of a thermoplastic resin to replace the more common thermoset resin. This may offer improved corrosion resistance and enhanced drainage tolerance. It could also reduce the processing time and may provide a cleaner working environment and infinite shelf life. This research will be followed by the preparation of educational materials, encompasssing the properties and design of this new construction material, to be used for instructional purposes. This research will likely result in the use of FRP in building construction which is currently being seriously considered by building designers because of the potential of improving manufacturing and lowering production costs. Professor Yahagi is a first-rate researcher and his Institute has recently acquired new facilities including a fire hood and a braiding machine which allows fire testing and manufacturing of the FRP composites. The Japanese construction industry is far more advanced in this technology than the U.S. Professor Nanni, who is a U.S. expert in this area, should obtain valuable information that he would be unable to obtain in the U.S. Professor Tsuji has visited Professor Nanni at his university for three months and this experience should assist them in the formulation of a curriculum course incorporating the reserach findings and new technologies for using FRP in building construction. Since previous collaborations between these researchers have been successful, it is anticipated that results from this project will be fruitful, as well, and of possible use throughout the world
