摘要:

锂铝硅玻璃与聚氨酯胶片之间的界面粘接性能直接影响航空透明件的结构安全性与服役可靠性,等离子体表面改性是增强界面粘接性能的有效途径。本文对锂铝硅玻璃表面进行不同速率下的等离子体表面改性,采用静态接触角测量、扫描电子显微镜和X射线光电子能谱对表面改性效果进行表征,并通过剥离实验定量评估界面粘接强度。此外,结合湿热老化与紫外辐照实验,对粘接界面的环境稳定性进行了评估。结果表明,等离子体表面改性速率为5 mm/s时,玻璃表面能的极性分量提升至42.87 mN/m,表面形成均匀的纳米级粗糙形貌,含氧官能团含量在此条件下达到峰值,表面改性取得了最为理想的效果。锂铝硅玻璃与聚氨酯胶片复合后仍保持较高的可见光透过率和较低的雾度,界面剥离强度达到23 620 N/m。经湿热与紫外环境老化后,该参数下改性的界面同样表现出最优的稳定性,性能衰减程度最低。通过控制等离子体表面改性速率可有效调控锂铝硅玻璃的表面能状态与化学组成,从而显著增强其与聚氨酯的界面粘接性能,研究结果对航空透明件材料界面的可靠性设计与工艺优化具有指导价值。

Abstract:

The interfacial bonding performance between lithium aluminosilicate glass and polyurethane films directly impacts the structural safety and service reliability of aerospace transparent components. Plasma surface modification serves is an effective method to enhance interfacial bonding performance. Through plasma surface modification at varying rates on lithium aluminosilicate glass surfaces, this paper characterized the effect of surface modification using static contact angle measurement, scanning electron microscopy, and X-ray photoelectron spectroscopy, while quantitatively evaluating interfacial bonding strength via peel-off tests. Environmental stability assessments were conducted through combined wet-heat aging and ultraviolet irradiation experiments. Results demonstrates that when the plasma surface modification rate is 5 mm/s, the polar component of the glass surface energy increases to 42.87 mN/m, forming a uniform nanoscale roughness morphology on the surface, and the oxygen-containing functional groups achieves peak content under these conditions, indicating optimal surface modification outcomes. The composite of lithium aluminosilicate glass and polyurethane film has high visible light transmittance and low haze, and the interfacial peel strength is 23 620 N/m. After aging in wet-heat and ultraviolet environments, the modified interfaces maintain superior stability and minimal performance degradation. By controlling plasma surface modification rates, the surface energy state and chemical composition of lithium aluminosilicate glass can be effectively regulated, significantly enhancing its interfacial bonding with polyurethane. These findings provide valuable guidance for reliability design and process optimization of aerospace transparent component interfaces.
