摘要
本文采用拉挤成型工艺制备 GFRP 棒材,并测量了其在不同条件下的抗拉强度和弯曲强度。结果表明:GFRP 棒材在 120℃、150℃ 下分别保温 500h、800h 和 1 000h 后,其抗拉强度虽有所下降,但仍高于或接近于同规格钢丝的抗拉强度;而弯曲强度却随加热温度的升高而明显下降。
In the paper, GFRP bar was fabricated by the technology of drawing and squeezing, and its tensile strength and bending strength under different conditions were measured. The results indicated that the tensile strength was reduced slowly after holding 500h, 800h and 1000h at 120℃ and 150℃, respectively, but its tensile strength was still higher than that of wire with the same size. Whereas its bending strength was dropped obviously with the increasing of temperatures.
