摘要:
采用钢板蒙皮与玻璃纤维增强复合材料(GFRP)拉挤成型的空心方管芯材组成夹层结构,运用四点弯曲试验方法,开展了钢蒙皮复合材料芯材夹层梁的受弯性能试验,研究了其受力性能情况、跨中上下面板应力分布和跨中挠度。运用换算截面法推导出钢蒙皮复合材料芯材夹层板截面有效抗弯刚度,并采用材料力学理论推导出夹层板跨中挠度计算公式,计算各试件的跨中上下面板应力分布情况和跨中挠度。研究结果表明:当芯材厚度一致时,试件的跨中挠度随着钢板面层厚度的增加而逐渐减小;跨中挠度理论值与试验值吻合较好。
Abstract:
Sandwich structure consisting of steel and glass fiber reinforced composite (GFRP) core pultruded hollow square tube was proposed. Bending experiment of metal facedcomposite core sandwich beam through using fourpoint bending test method was carried out. The distribution of strain, the mid-span deflections and the ultimate failure of the slab were analyzed. The effective bending stiffness of metal facedcomposite core sandwich panel was deduced by transformed section method, and the mid-span displacement computational formula was deduced by mechanics of materials theory. The mid-span deflections of samples were calculated. The theory results and test results were compared and they fitted well. The study results show that when the thickness of the core is constant, the mid-span deflection decreases with increasing thickness of metal faced.
