| Abstract:The microscopic morphology,fiber size distribution,specific surface area,water retention value, crystalline structure, thermal stability of two kinds of imported and domestic PPTA pulps were compared. And the influence of morphological stuctrue and properties of the pulp on the enhancement effects of the composite materials were discussed. Results showed that the domestic PPTA pulp still needed to funthen improve. And more flxible fiber morphology, larger specific surface area, more uniform fiber distribution, stronger hydrogen bonding in matrix and more perfect crystalline structure were very helpful to the properties of the composite materials. |
