Abstract: This paper proposes an innovative low-cost isolator with lightweight and cost-effective features for use in low-rise residential buildings. The low-cost laminated isolator is formed by plastic shims with unsaturated polyester fiber reinforcement between rubber layers. Bending and tensile tests of the resin and the unsaturated polyester fiber reinforcement engineering plastic plates have been carried out to investigate their characteristics. The cold bonding forming process and hot vulcanization molding process of the simple isolator are introduced in this paper. Performance tests are systematical carried out to characterize the isolator in terms of mechanical behavior (e.g., compression, shear and their relationship), dynamic properties (e.g., damping) and ultimate states. A connection construction scheme is put forward for low-rise rural building. This simple isolation technology provides scientific and technological support for popularizing seismic isolation technology in underdeveloped rural areas, which is of theoretical and practical significance.
