| Abstract: | The weight and color change of wood plastic composites was analysed and the thermal characteristic was studied by using differential scanning calorimetry under natural weather. The results showed that the reason of the weight gain of the material was moisture absorption. Water had some important effects on molecular structure of the material, and it was the key factor affecting the weathering of the material. |
