| Abstract:In this study the effect of moisture content of PPTA paper-based composite in hot calendering process on its mechanical and electrical properties was investigated. The surface morphology, the pore structure parameters and crystallinity of PPTA aramid paper were studied by using scanning electron microscopy(SEM), automatic mercury porosimeter(MIP) and X-ray diffraction(XRD) respectively. The results showed that the paper surface and the internal structure became more smooth and close, the crystallinity of the paper increased along with the increasing of moisture content in calendaring process. The crystallinity reached up to the maximum of 71.17% increased by 59.39% compared with the dry paper when the moisture content was 120%. In addition, the mechanical and electrical properties of para-aramid paper was also improved. |
