Effect of Polyphenylene Sulphide Particles and Films on the Properties of Polyphenylene Sulphide Composites

Abstract

Glass fibre-reinforced polyphenylene sulphide composites were prepared by hot-pressing glass fibre fabrics and polyphenylene sulphide resins. The effects of different polyphenylene sulphide resin forms on the properties of the composites were investigated using scanning electron microscopy, dynamic mechanical analyser, pendulum impact tester and universal testing machine. The results showed that different polyphenylene sulphide resin forms had nearly no effect on the glass transition temperature of the composites, which are all located at about 100 ℃. Compared with other polyphenylene sulphide composites, the bending strength of polyphenylene sulphide film composites was the highest, reaching 314.58 MPa, and the impact strength of polyphenylene sulphide particle composites was the highest, reaching 245.4 KJ/m2. The bending strength and impact strength were calculated using a standard fraction, and the highest standard fraction was obtained when the ratio of polyphenylene sulphide film to particle was 1:2. The impact strength and bending strength could be obtained. The impact strength reached 229.8 KJ/m2, and the bending strength reached 284.16 MPa.

Improving film adhesive joining performance of poly(phenylene sulfide)/carbon fiber thermoplastic composite laminates by plasma surface treatment

“…On the other hand, Figure 5 revealed that there were certain new IR peaks formed after plasma treatment, such as functional O-H peaks at 3364 cm À1 , carbonyl C = O stretching at 1643 cm À1 , vibration of C-O at 1286 cm À1 , stretching vibrations of -SO 2 -at 1200 cm À1 , and S = O at 1074 cm À1 . In the literature, [55][56][57] it was discussed that appearance of these new IR peaks could be due to the oxidative action of the plasma treatment on the PPS polymer structure.…”
