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 °C. 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/m. 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/m, and the bending strength reached 284.16 MPa.
通过热压玻璃纤维织物和聚苯硫醚树脂制备了玻璃纤维增强聚苯硫醚复合材料。使用扫描电子显微镜、动态力学分析仪、摆锤冲击试验机和万能试验机研究了不同形态的聚苯硫醚树脂对复合材料性能的影响。结果表明,不同形态的聚苯硫醚树脂对复合材料的玻璃化转变温度几乎没有影响,均位于约100℃。与其他聚苯硫醚复合材料相比,聚苯硫醚薄膜复合材料的弯曲强度最高,达到314.58MPa,聚苯硫醚颗粒复合材料的冲击强度最高,达到245.4kJ/m²。弯曲强度和冲击强度采用标准分数计算,当聚苯硫醚薄膜与颗粒的比例为1:2时,获得最高标准分数。可获得冲击强度和弯曲强度。冲击强度达到229.8kJ/m²,弯曲强度达到284.16MPa。
