- the present invention can have the following embodiments.
- a vibration damping material in which carbon nanocoils are dispersed in a matrix resin is provided. Since carbon nanocoils have electrical conductivity, vibration energy generated in the damping material can be converted into heat, and vibration energy can be quickly attenuated.
- the carbon nanocoil since the carbon nanocoil is coiled, it has a larger contact area with the matrix resin than conductive materials other than carbon nanocoils such as carbon nanotubes and graphite. Therefore, by dispersing the carbon nanocoil in the matrix resin, the vibration energy generated in the damping material is converted into heat in a shorter time than when conducting materials other than the carbon nanocoil are dispersed in the matrix resin. Therefore, vibration energy can be attenuated in a shorter time.
- carbon nanocoils are coiled, unlike conductive materials other than carbon nanocoils, they are deformed like springs and immediately revert to their original shape. Therefore, by dispersing the carbon nanocoil in the matrix resin, the vibration energy is attenuated because the force to restore the shape before deformation acts on the damping material.
- the carbon nanocoil dispersed in the matrix resin also vibrates, and the vibration energy received from the matrix resin is converted into the stretching or shearing motion of the carbon nanocoil itself. Since vibration energy is consumed, vibration energy can be attenuated.
- the physical properties of the composite material are almost proportional to the filling amount of the filler. It is.
- the filler size is in the sub-micron region to the nano region, the surface effect is more dominant than the volume effect due to the overwhelming increase of the surface area relative to the volume.
- the carbon nanocoil has a nano-sized coil shape, the contact area with the matrix resin is larger than that of the conductive material other than the carbon nanocoil.
- carbon nanocoils contribute to vibration damping with a smaller amount than when conductive materials other than carbon nanocoils are used. Furthermore, since carbon nanocoils are coil-shaped, the contact area between the carbon nanocoils in the matrix resin is smaller than when using conductive materials other than carbon nanocoils, that is, non-coiled or conductive materials. . Therefore, the van der Waals force acting between carbon nanocoils is smaller than the van der Waals force acting between conductive materials other than carbon nanocoils, so carbon nanocoils are uniformly applied to the matrix resin. Can be dispersed. Thus, since the carbon nanocoil can be uniformly dispersed in the matrix resin, by dispersing the carbon nanocoil in the matrix resin, the strength can be enhanced and the vibration damping property can be sufficiently enhanced.
- a vibration damping material having high strength and high vibration damping properties can be obtained by dispersing carbon nanocoils in a matrix resin.
- a vibration damping material characterized in that carbon nanocoils and reinforcing fibers are dispersed in a matrix resin.
- a vibration damping material in which carbon nanocoils and reinforcing fibers are dispersed in a matrix resin is provided.
- the strength can be increased by dispersing reinforcing fibers in the matrix resin.
- high vibration damping can be obtained by dispersing carbon nanocoils in the matrix resin. Therefore, by dispersing carbon nanocoils and reinforcing fibers in the matrix resin, it is possible to improve the vibration damping performance without reducing the rigidity.
- Carbon nanocoils also act as anchors. Because of the anchor effect of the carbon nanowire, it is possible to suppress interfacial delamination between the matrix resin and the reinforcing fiber, so that it is possible to achieve high strength, for example, high bending strength and interlaminar shear strength.
