  • This study propose the organic fiber reinforcement for performance improvement of blast resistance. Proposed fibers are polyamide fiber, PET fiber and aramid fiber and fiber reinforcements were produced by ATY method. To evaluate strain energy absorption capacity of organic fiber reinforced concrete using organic fiber reinforcement, 4-point bending test and 3-point bending tests on notched beam were performed. Test results show that PET fiber reinforced concrete has outstanding performance. It is thought that the PET fiber is effective for the performance improvement of blast resistance.

  • Organic fiber reinforced concrete is applicable to many applications for construction material. In general, organic fibers have low tensile strength and elastic modulus, but they have many advantages such as high crack resistance, impact resistance, chemical resistance, flexural behavior and corrosion resistance. In this study, hybrid organic fibers were prepared by mixing polyamide (PA) fibers and high strength polyester (PET) fibers. Then, flexural performance test of fiber reinforced concrete containing hybrid organic fiber was performed. The energy absorption capacity of the hybrid organic fiber reinforced concrete was evaluated.
