Effect of PPTA Fiber Morphology on the Performance of Paper-Based Functional Materials

The beating characteristic of PPTA fiber and its influence on the performance of paper-based functional materials based on PPTA fiber and resin has been investigated in this study. The results show that the morphology of PPTA-pulp had significant influences on the mechanical and electrical properties of the composites. The sample contained with PPTA fiber of 35 °SR showed the increase in tensile strength, tearing strength and dielectric strength by 147.7%, 119.3% and 69.9% as compared with the untreated PPTA fiber.
