Abstract This paper presents an experimental investigation on the mechanical properties of sandwich tempered glass unidirectional composite laminate under uniformly distributed load. A total of sixty-four specimens are tested to investigate the influence of individual layer thickness of tempered glass panel (T), bearing length (BL), and length of loading end (LLE). According to this experiment, the failure modes of tested specimens were observed in detail during load procedure. The effects of the three variables on the ultimate bearing capacity, stiffness and stress distribution of sandwich tempered glass unidirectional composite laminate are discussed. The results indicate that the three variables have positive effect on bearing capacity and secant stiffness of the sandwich tempered glass unidirectional composite laminate. And the individual layer thickness of tempered glass panel has the greatest influence on the ultimate bearing capacity and secant stiffness of specimens. With increasing of thickness, bearing length and length of loading end, the bearing capacity and the stiffness are increased. Based on the results of parametric studies, the designed formulas are proposed to estimate the ultimate bearing capacity of sandwich tempered glass unidirectional composite laminate under local uniformly distributed load.

夹层钢化玻璃单向复合层压板力学性能试验研究

摘要 本文对夹层钢化玻璃单向复合层压板在均布​​载荷作用下的力学性能进行了试验研究。总共测试了 64 个试样，以研究钢化玻璃面板的单层厚度 (T)、承载长度 (BL) 和加载端长度 (LLE) 的影响。根据该实验，在加载过程中详细观察了测试样本的破坏模式。讨论了三个变量对夹层钢化玻璃单向复合层压板极限承载力、刚度和应力分布的影响。结果表明，三个变量对夹层钢化玻璃单向复合层压板的承载力和割线刚度都有积极影响。而钢化玻璃板的单层厚度对试件的极限承载力和割线刚度影响最大。随着厚度、承载长度和加载端长度的增加，承载能力和刚度增加。根据参数化研究结果，提出了局部均布荷载作用下夹层钢化玻璃单向复合层压板极限承载力的估算公式。
