摘要: 以杨木单板为基材、玻璃纤维为增强材料,按照单板层积材的结构设计制备增强复合材料层板。通过对复合 材料层板进行应力分析,研究玻璃纤维布的铺放位置和层数对复合材料层板力学性能的影响。结果表明:玻璃纤 维越靠近复合材料层板的表层,层板的静曲强度和弹性模量越大;玻璃纤维向心层靠近,其增强作用明显减弱。随 着玻璃纤维布层数的增加,复合材料层板的静曲强度和弹性模量均呈上升趋势。玻璃纤维对复合材料层板的力学 性能有显著的增强作用,且玻璃纤维布的铺放位置和层数与复合材料层板的力学性能密切相关。Abstract: Using poplar veneer as base material and glass-fiber fabric as reinforcing material, the study made glass-fiber fabric reinforced poplar veneer composite laminates in accordance with the structure principle of laminated veneer lumber. This paper aims to probe into the influence of locations and layer numbers of fiber-glass on the mechanical properties of composite laminates, to which the stress analysis was conducted. The results showed that: 1) the closer the fiber-glass to the surface of the composite laminates was, the higher the modulus of rupture (MOR) and elasticity (MOE) values would be; 2) the MOR and MOE values decreased significantly as the fiber-glass moved to the core of composite laminates; 3) the MOR and MOE values increased when more layers of fiber-glass were added to the composite laminates. In a nutshell, the locations and the numbers of the fiber-glass significantly contribute to the mechanical properties of composite laminates.
