Experimental Research on Bending Property of GFRP Monopole Communication Tower
Based on the determination of bending displacement-load experiments, the bending elastic modulus of Glass Fiber Reinforced Plastic commonly used on monopole communication tower is studied first in this paper. The experiments prove that the bending elastic modulus is low and indicate that 1:1 bi-directional glass cloth pavement does not meet the mechanical requirements of monopole tower and is not an economic design. In order to achieve mechanical characteristics of monopole tower, GFRP is adjusted to pavement of 4:1. Cross ply unidirectional glass cloth is used as main reinforced material, and the angle to horizontal direction is 90 degree and 0 degree. The bending elastic modulus of this secondary design is as nearly 10 times as the original design, and the result is proved by theory and experiments.
