| Abstract:With polyphenylene sulfide (PPS) fiber as the insulating reinforcing phase， para-aramid precipitated fiber as the auxiliary phase， and glass fiber as the skeleton material， PPS/aramid/glass fiber composite paper was prepared via a wet-forming process. The effects of PPS fiber content on the microstructure， physical properties， electrical insulation properties， and thermal stability of the PPS/aramid/glass fiber composite paper were systematically investigated. The results showed that the PPS/aramid/glass fiber composite paper exhibited optimum comprehensive properties at a basis weight of 105 g/m² with PPS fiber content of 20%， achieving a tear strength of 1 733.8 mN， a tensile strength of 25.4 kN/m， and volume resistivity reached 8.816×1014 Ω·m， power frequency breakdown strength reached 16.09 kV/mm， dielectric loss reached 1.85×10-13， and thermal shrinkage rate was 4.8%. The PPS/aramid/glass fiber composite paper held application potential as a high-performance insulating paper. |
