Rheological Behaviors of Polymer Impregnated Maple Veneer

Chunfeng Li, Qingwen Wang, Mingli Liu, Haigang Wang


The objective of this study was to determine rheological behaviors of maple veneer plastic composite (MVPC) prepared by full cell preparation technology through the use of a rotational rheometer. The results showed that at 25 to 105 °C, the storage modulus G' and loss modulus G'' of the MVPC were apparently higher than that of the control. In the range 105 to 210 °C, the storage modulus G' of the MVPC was basically the same as that of the control, and the loss modulus G'' was slightly higher than that of the control. At 105 °C, the Tanδ curve of the MVPC had an obvious peak, which indicated that the glass transition temperature (Tg) of the MVPC was about 105 °C. The rheological behavior of the MVPC with different impregnation weight gain rates showed that the MVPC with a 55% impregnation weight gain rate had higher G', G'', and Tanδ.
