Wood-plastic composite is a kind of viscoelastic materials.
The dynamic viscoelastic behavior of materials is represented by storage modulus, loss modulus, tanδ and so on, which are functions of temperature.
Materials and Methods The WPC was manufactured using a formulation composed of bamboo flours, PVC, heat stabilizer, lubricant and foaming agent.
The fact is that all kinds of materials with different bamboo flours levels present the same variation trend.
