Abstract

The invention discloses an energy-consuming damping material, and a preparation method and application thereof. The energy-consuming damping material consists of glass fiber wires and fillers, wherein the glass fiber wires are perpendicular to one another and are internally filled with the fillers. A main material of the energy-consuming damping material adopts a mixture of epoxy and rubber, so that the elastic modulus is smaller, the deformation is large under the action of a force, and the damping is higher; when an earthquake occurs, energy can be consumed by utilizing the shear deformation of the device or by utilizing the friction due to high damping, so that a main structure can absorb a small amount of energy, so that the requirements on shock absorption and shock resistance are met, and the safety of the structure is guaranteed.

Description

technical field [0001] The invention relates to a new anti-seismic material, in particular to an energy-consuming anti-seismic material, a preparation method and an application thereof. Background technique [0002] Energy dissipation shock absorption technology is a more reasonable, effective, safe and economical engineering anti-seismic method developed rapidly in recent years. This method has completely changed the traditional anti-seismic thinking of "reinforced" structures. Energy-dissipating elements are designed between structures to consume seismic energy through friction, shear deformation, or plastic deformation of their devices, so as to reduce the seismic response of the main structure or alleviate it. Destruction, to achieve the purpose of shock absorption control. At present, a variety of energy dissipation devices have been researched and developed, such as friction energy dissipation devices, metal energy dissipation devices, viscoelastic energy dissipation ...
