| 英文摘要 | In this paper, a series of static/dynamic tensile tests are performed for glass fiber reinforced plastic (GFRP) composites. Using the combination of high-speed photography and digital image correlation (DIC) technology, true stress-strain curves in different directions and strain rates are obtained. We also obtained the dynamic failure strain of the material in different directions, which are used to accurately describe the dynamic tensile and failure behavior of the material. The experimental results show that there is a stiffness change point N in three directions under different strain rate (10(-3) s(-1), 10 s(-1), 100 s(-1)) tensile conditions. The stiffness before and after N point is recorded as E-initial and E-changed respectively. The values of E-changed in weft direction and warp direction are about 30% to 50% of E-initial, while E-changed in tilt direction is only about 10% of E-initial. The fiber has the highest strength in the weft direction and the tilt direction has the lowest strength. With the combination of high-speed photography and DIC technology, the dynamic failure parameters of different directions under the strain rate of 100 s(-1) are obtained. The dynamic failure strains in three directions are 0.245, 0.373 and 0.341, respectively. The parameters are verified by impact three-point bending test. These works can more accurately describe the dynamic mechanical behavior of glass fiber reinforced plastic (GFRP) composites and provide reference for the design of GFRP structures. |
