Abstract:

After natural evolution of history, subtle multi-level structure and excellent interface design have been formed inside bamboo. Rigid vascular bundles are gardenly and evenly distributed in flexible parenchymal cells, and a natural "island-chain structure" has been built, which not only offers high strength and toughness, but also enhances energy absorption and damping effect to resist natural disasters (rain, snow and wind), through the deformation of parenchymal cells and void structures, as well as crack deflection of intercellular layer. This paper was conducted to describe the vibration damping performance of bamboo and analyze the action mechanisms of environmental factors (temperature and humidity) upon such performances, from the two aspects of multi-scale structural characteristics (macro-micro) and chemical components (linear cellulose molecular chain-amorphous lignin polymers). Further, the vibration damping mechanisms of bamboo-based composites were summarized. The structure and technological characteristics of bamboo-based damping composites were analyzed, and the effects of four kinds of laminated structures (basic damping, impact damping, lightweight damping and quiet damping) on vibration damping properties of bamboo-based composites were also obtained among the three current widely-used assembly patterns of wood/bamboo, bamboo/plastic, and bamboo fiber/rubber particle. The application prospects of bamboo-based damping composites were discussed in the fields of sports, architecture, transportation and electronic information, according to the integrated design principle of "material-structure-function". The general scientific problems and key technologies those need to be solved urgently were raised in the end of the paper, towards biological vibration damping characteristics of bamboo, regulatory mechanisms of bamboo-based damping composites, research and development of novel intelligent bamboo-based damping material, and product standardization. Bamboo-based damping composites possess the function of energy absorption, energy consumption reduction, anti-vibration and noise reduction, which is of great significance for the prevention of noise and vibration pollution in the fields of construction, transportation and machinery.
