Abstract:
The unidirectional PBO fiber sheets are layered on the concrete to strengthen the flexural properties. The bending performance of the reinforced concrete with different fiber volume content using threepoint bending experiment has been studied. And a digital scanning technology has been used for investigation destruction feature of the concrete. The results show that the flexural strength of the concrete has been significantly improved by PBO fiber sheets, and flexural strength of the concrete becomes higher and higher as raising the fiber volume fraction. When the fiber volume content is 1.35%, the bending strength of the concrete is about 3.6 times compared with the plain one. The destruction of the concrete changes from the brittle fracture of plain concrete to the toughness fracture.
