摘要: 碱铝硅玻璃(R2O-RO-Al2O3-SiO2)作为重要的新兴玻璃品种,已在屏幕保护、高铁、航空及光伏发电等领域得到广泛应用。本文以碱铝硅玻璃为研究对象,依据拉伸法测量原理,设计光路系统并搭建测量装置,以直径0.70~0.80 mm的玻璃纤维为试样,改变玻璃组成(R2O、RO、Al2O3、SiO2)和光源波长(640、587、518 nm)分别测量玻璃应力光学系数,探究玻璃组成和光源波长对应力光学系数的影响规律。结果表明:玻璃应力光学系数取决于各氧化物组成和应力光学系数因子,具有加和性;应力光学系数随测试光源波长增加而减小,呈非线性关系;玻璃的应力光学系数与折射率的三次方n3、泊松比μ成正比,与弹性模量E成反比。本工作所获得的氧化物应力光学系数因子可为碱铝硅玻璃应力光学系数设计提供技术支持和预测依据。

Abstract: Alkali-aluminosilicate glass (R2O-RO-Al2O3-SiO2) has emerged as an important new type of glass, finding applications in screen protection, high-speed rail, aviation and photovoltaic. This study investigated stress-optical coefficient of alkali-aluminosilicate glass by designing an optical path system and constructing a measurement device based on the tensile measurement method. Glass fibers with diameters of 0.70 mm to 0.80 mm were used as samples. The influences of glass composition (R2O, RO, Al2O3, SiO2) and light source wavelengths (640, 587, 518 nm) on stress-optical coefficient were investigated. The main findings indicate that the stress-optical coefficient is determined by composition of each oxide and stress-optical coefficient factors, exhibiting additivity. The stress-optical coefficient decreases nonlinearly with increasing light source wavelength. Additionally, the stress-optical coefficient of the glass is proportional to the cube of the refractive index n3 and Poisson ratio μ, while being inversely proportional to the elastic modulus E. The oxide stress-optical coefficient factors obtained in this study provide technical support and predictive guidance for the design of stress-optical coefficients in alkali-aluminosilicate glass.
