Low Temperature Performance of Fiberglass Geogrid


Article Preview

The tensile test to the fiberglass geogrid had been carried on, in the normal temperature, the low temperature, the water immersion, the freezing and the freeze-thaw cycle and so on conditions. The results indicated, the fiberglass geogrid had achieved saturated after been immersed 12h, the water absorption was about 20%, the tensile strength reduced approximately 80%; the tensile strength was dropped slightly on the next freezing test and the freeze-thaw cycle test. So it could be stated that the fiberglass geogrid had the good low temperature performance. Then the interlaminar shearing test had been conducted in the different temperature to the composite structure in which the fiberglass geogrid was laid or not. The result showed that the interlaminar shearing strength had weaken about 20% when laid down the fiberglass geogrid, and along with temperature drop, the shearing strength increased gradually. This research provide the reference for used the fiberglass geogrid correctly in the cold region, had great practical value.
