Abstract
The invention discloses a vertical axis wind power generator blade and a manufacturing method thereof. The blade has a three-layer structure including an outer metal layer, a middle gradient composite material layer and an inner low density foam sandwiched material layer. The metal layer has a high hardness, is resistant to scratch, and can withstand a hard object impact. The middle gradient composite material layer can provide good rigidity and strength at the same time as well as excellent damping characteristic. The inner sandwiched structure is formed of a low density porous foam sandwich and a gradient composite material layer, and the low density porous foam sandwich and the gradient composite material layer can generate shearing effects under the action of an external load, to further improve rigidity. Furthermore, the porous structure of the foam material can absorb the load applied to the blade due to sudden impact and vibration effects, so as to ensure safe and reliable operation of the blade.
