A FRP reinforced rubber vibration isolator and manufacturing method thereof, relate to a vibration isolator and a manufacturing method thereof. The vibration isolator is formed by a rubber layer and a FRP plate with adhesive layers arranged on the upper and lower surfaces which are staggeredly superposed, vulcanized and bonded, wherein the FRP plate is made of fiber reinforced materials and a resin substrate, the fiber reinforced material is one or more of glass fiber, high-strength glass fiber, carbon fiber, aramid fiber, basalt fiber or polyester fiber, the resin substrate is one of the epoxy resin, unsaturated polyester resin, phenolic resin or vinyl ester resin, the FRP plate is formed by superposing 1 to 50 single layer plate which have different principal directions. The manufacturing method comprises preparing FRP plate, arranging adhesive layer, superposing, vulcanization molding. The vibration isolator has higher bearing capacity and excellent damping performance, durability, corrosion resistance, and has simple and applicable manufacturing method.
