Problems solved by technology

[0002] The research on the strengthening of the automobile body and the field of vibration and noise reduction has always been an important topic for the improvement and promotion of the automobile industry. In the existing technology, the technical means used by the automobile industry to achieve the above goals is usually to use the paste reinforcement film car to realize the body reinforcement. Vibration and noise reduction is to paste damping film or spray damping paint, but in the construction application, only one of them can be selected, that is, the use of reinforcement will not achieve vibration and noise reduction, and the use of damping materials will not achieve body reinforcement. Therefore, there is an urgent need for a material that is convenient for construction and can simultaneously realize the reinforcement of the automobile body and the vibration and noise reduction.
