摘要:

以注塑和吹塑成型的有机玻璃观察窗为研究对象,对不同服役环境下经聚能切割索侵彻断裂的有机玻璃结构件断面进行微观形貌、结构分析和动静态力学性能测试,发现注塑样品表现出较好的韧性和抗冲击能力,而吹塑样品则具有更高的力学强度,揭示了粒子侵彻过程中高温致分子链降解/断裂和冲击波破坏的两阶段失效机制,为有机玻璃结构件成型过程调控和服役环境设计提供参考。

Abstract:

In this study, injection⁃molded and blow⁃molded organic glass structural parts were investigated by analyzing their microscopic morphology, structure, and dynamic/static mechanical properties. Their cross⁃sections obtained from penetration fracture using a shaped cutting wire under different service environments were examined. The results indicated that injection⁃molded samples presented superior toughness and impact resistance, whereas blow⁃molded samples obtained higher mechanical strength. A two⁃stage failure mechanism was proposed, involving high⁃temperature⁃induced molecular chain degradation/fracture followed by shock⁃wave damage during particle penetration. This work provides insights for optimizing the molding process of organic glass structural parts and designing their service environments.

Key words: organic glass, poly(methyl methacrylate), penetration fracture, impact damage, failure mechanism
