Preparation and Mechanical Properties of Poly (arylene sulfide sulfone)/Glass Fiber Cloth Composites

摘要

Poly (arylene sulfide sulfone)/glass fiber cloth composites (PASS/GFC) were prepared through compression moulding. The optimum processing conditions including temperature, time and pressure were discussed in detail. The cross-linking reaction, mechanical and dynamic mechanical properties were also characterized. The results showed that the optimum processing temperature, pressure and time were 325 ℃, 5 MPa and 15 min, respectively. The thioether group (-S-) was oxidized and converted to sulfoxide (-SO-) and sulfone (-SO_2-) groups during the crosslinking reaction proved by Fourier transform infrared spectrometer. The mechanical and dynamic mechanical analysis measurements showed that mechanical properties, including tensile, bending, impact and storage modulus increased continuously with an increase of the GFC contents.
