Abstract: Curing behavior, thermal properties, dielectric properties and mechanical properties of quartz fiber reinforced polytriazole resin composites were investigated in this paper. The composites can be cured at 80℃, and Tg of one of the composites reaches 230℃ after the post-processing of 120℃/2h+150℃/2h+180℃/2h+200℃/2h+ 250℃/2h. Dielectric constant of this composite is 3. 8. Mechanical properties of the composites increase by the post-processing temperature. Flexural strength arrives at 795MPa after the post-processing at 250℃, which retention rate at 180℃ is 59%. Interlaminar shear strength is 61MPa at ambient temperature.
