【摘要】：采用人工加速老化的方法模拟湿热环境,通过泡桐木玻璃纤维增强复合材料夹芯结构的双悬臂梁拉伸剥离试验,研究湿热环境对玻璃纤维增强复合材料(GFRP)面板和泡桐木芯材的粘结性能的影响。试验结果表明,90 d湿热加速老化后泡桐木复合材料夹芯结构的能量释放率下降了32.3%,芯材泡桐木顺纹抗拉强度下降了11.6%,GFRP面板拉伸模量下降了11.0%。
[Abstract]:The method of artificial accelerated aging was used to simulate the wet and hot environment. The tensile peeling test of double cantilever beam with paulownia wood glass fiber reinforced composite sandwich structure was carried out. The effect of heat and humidity on the bond properties of glass fiber reinforced composite (GFRP) panel and paulownia wood core was studied. The results showed that the energy release rate of paulownia wood composite sandwich structure decreased by 32.3and the tensile strength of core paulownia wood decreased 11.6g / GFRP panel tensile modulus decreased by 11.0 after 90 days of accelerated aging.
