摘要
观测了三号航空有机玻璃 ( YB- 3)在不同溶剂作用下的应力 -溶剂银纹临界应力σc和银纹形貌。研究了吸水、紫外光辐照等单一环境因素和多个因素循环作用对 σc和银纹形貌的影响 。
The critical stresses of stress\|solvent crazing,σ c,of a nonoriented aviation organic glass, YB-3(PMMA), were measured with various organic solvents and the craze morphology was observed. The effects of environmental factors such as water sorption, UV radiation, and their combination or cycling on σ c and the craze morphology were studied, and the influencing mechanisms were discussed.
