The scientific aim of this project is to participate in an in-depth research and development investigation on the potential use and mechanical properties of aramid fiber reinforced concrete (AFRC) already in progress in Japan. Aramid reinforcement considered in this study is made by weaving filaments in braided form and impregnating with epoxy resin. Fiber bundles in rod-like form are expected to replace steel reinforcing bars or prestressing tendons, whereas, cut in short lengths, can be used as discontinuous-type reinforcement. The proposed project will be conducted at Mitusi Technical Research Institute, Tokyo, Japan. The Institute has developed the fiber braiding technology using U.S. produced aramid filaments and is presently very active in various fields of construction research.

该项目的科学目的是参与一个深入的 对潜在用途的研究和开发调查， 芳纶纤维混凝土力学性能 在日本已经在进行中。 考虑的芳纶增强材料 该研究是通过编织编织形式的长丝进行的， 用环氧树脂浸渍。 纤维束呈棒状， 期望取代钢筋或预应力筋， 然而，切割成短的长度，可以用作不连续型 加固. 拟议项目将在Mitusi进行 日本东京技术研究所。 研究所 使用美国生产的芳纶开发了纤维编织技术 目前在各种领域非常活跃， 建设研究。
