摘　　要：新一代锂铝硅玻璃逐渐成为航空透明件的主流结构材料,由于具有较高的弹性模量和优异的离子交换能力,锂铝硅玻璃经过化学强化处理后具有优异的力学性能,能够很好地满足航空透明件轻质、高强的需求。本文旨在探讨化学强化工艺对3~6 mm厚锂铝硅玻璃抗冲击性能的影响。采用不同强化条件制备样品,通过落球冲击测试及理论计算,分析应力分布对抗冲击性能的作用。研究发现,对于厚锂铝硅玻璃,随着应力层深度的增加,中心应力增长较慢,且厚度越大的锂铝硅玻璃,中心应力增长速度越慢,抗冲击性能随应力层深度增加而提升,这与在薄锂铝硅玻璃中的规律不同。The new generation of lithium aluminosilicate glass has gradually become the mainstream structural material for aerospace transparencies.Due to its high elastic modulus and excellent ion exchange capability,lithium aluminosilicate glass exhibits superior mechanical properties after chemical reinforcement treatment,well meeting the requirements of lightweight and high strength for aerospace transparencies.This paper aims to explore the effect of chemical reinforcement processes on impact resistance of 3~6 mm thick lithium aluminosilicate glass.Samples were prepared under different reinforcement conditions,and the effect of stress distribution on impact resistance was analyzed through ball-drop impact testing and theoretical calculations.It is found that for thick lithium aluminosilicate glass,as the depth of the stress layer increases,the growth of central stress is slower.Moreover,thicker lithium aluminosilicate glass exhibits a slower growth rate of central stress,and its impact resistance improves with the increase in the depth of the stress layer,which differs from the pattern observed in thin lithium aluminosilicate glass.
