Herein, novel graphene‐reinforced elastomeric isolators (GREI) are proposed. Elastomeric isolators (EIs) are special devices used for seismic isolation of structures. They are made of alternate layers of steel and rubber (steel‐reinforced EI [SREI]), and they position between the structure and its foundations to decouple them. The heavy weight and complex manufacturing process of SREI drives costs up, and this restricts their use to strategic buildings such as hospitals and civic centers. In recent years, alternative materials have been proposed to replace the steel sheets of SREI, e.g., glass or carbon fiber‐reinforced EIs (FREIs). However, their mechanical behavior requires further investigation before being implemented in existing and new structures safely. As a promising alternative, GREI is proposed here to overcome the heavy weight and long manufacturing process of SREI and the mechanical limitation of FREI to seismic excitations.

用于结构隔震的石墨烯-橡胶层状功能复合材料

本文提出了新型的石墨烯增强弹性体隔离器（GREI）。弹性隔离器（EIs）是用于地震隔离结构的特殊设备。它们由钢和橡胶的交替层（钢增强EI [SREI]）制成，并且它们位于结构与其基础之间以使它们分离。SREI的沉重重量和复杂的制造工艺推动了成本的上升，这将它们的使用限制在诸如医院和市政中心等战略建筑中。近年来，已经提出了替代材料来代替SREI的钢板，例如玻璃或碳纤维增强的EI（FREI）。但是，在安全地将它们应用于现有结构和新结构之前，需要进一步研究其机械性能。作为有前途的选择，
