The contact surface is crucial in determining the ability of membranes or laminas to absorb energy during penetration. This study conducted experiments to explore the mechanical properties of the pristine graphene oxide (GO) membrane when dry, as well as the anti-penetration performance of four surface-modified GO membranes (dry, oil, water, and grease) under various loading velocities. Dynamic penetration occurs when the kinetic energy exceeds a specific threshold, as opposed to the quasi-static outcomes. Additionally, the examination of failure mode indicated that the GO membrane demonstrates significant elastic rebound when subjected to comparatively lower levels of dynamic loading. Further analysis after penetration revealed a transition from brittleness to ductility under dynamic loading conditions. Uniaxial tensile tests of aluminium sheets revealed a distinct negative velocity sensitivity behaviour. Moreover, surface treatment with the GO membrane can enhance the penetration failure strength and energy absorption capacity of the sheet. This study provides crucial insights into the physical principles governing the energy absorption of membrane structures and how they are influenced by surface conditions.

接触表面对于确定膜或层板在穿透过程中吸收能量的能力至关重要。本研究进行了实验，探讨原始氧化石墨烯 ( GO ) 膜干燥时的机械性能，以及四种表面改性GO膜（干燥、油、水和油脂）在不同加载速度下的抗渗透性能。当动能超过特定阈值时，就会发生动态穿透，这与准静态结果相反。此外，失效模式的检查表明，GO膜在承受相对较低水平的动态载荷时表现出显着的弹性回弹。渗透后的进一步分析表明，在动态载荷条件下，脆性转变为延展性。铝板的单轴拉伸试验揭示了明显的负速度敏感性行为。此外， GO膜的表面处理可以增强板材的穿透破坏强度和能量吸收能力。这项研究为控制膜结构能量吸收的物理原理以及它们如何受到表面条件的影响提供了重要的见解。
