| Abstract: | The interfacial morphology and interlaminar shear strength of glass fiber reinforced plastic/magnesium laminate(GFRP/Mg)were observed,tested and analyzed by scanning electron microscope(SEM)and short beam bending teat.The results show that the surface energy of magnesium alloys treated by phosphating and permanganate are about 53.7%and 64.6%higher than that by abrasion-only,respectively,and the surface wettability of magnesium alloy are obviously improved by phosphating and permanganate.However,the surface treatment of magnesium alloy has little influence on the interlaminar shear strength of GFRP/Mg laminate.The interlaminar shear strengths of GFRP/Mg laminates based on three surface treated magnesium alloys are similar.The surface roughness of magnesium alloy has a great influence on the interlaminar shear strength of GFRP/Mg laminate.When the surface roughness of magnesium alloy is 0.92μm,the interlaminar shear strength of GFRP/Mg laminate is about 13%higher than that of magnesium alloy with surface roughness of 0.23μm.When interlaminar shear failure occurs,the GFRP/Mg laminate is mainly destroyed by interface bonding failure. |
