| Abstract:The phenolic resin distribution and morphological structure during the impregnation and curing process of carbon paper were studied， exploring the effect of impregnation and hot pressing process on the properties of carbon paper. The results showed that the maximum impregnation increment of phenolic resin for pre-impregnated carbon paper was up to 154.9% when the impregnation time and phenolic resin concentration were 4 min and 11%， respectively. The prepared carbon paper after hot-pressed had the best performance when the hot pressing temperature， time and pressure were 160 ℃， 20 min and 3.0 MPa， respectively， of which the resistivity and tensile strength of carbon paper were 27.1 mΩ·cm and 103.9 N/cm， respectively. |
