摘要
研究了高性能热塑性树脂双酚 A 型聚砜(PSF)、酚酞型聚醚酮(PEK-C)增韧聚苯硫醚(PPS)的破坏韧性和破坏形态。实验表明:PSF 与 PEK-C 两种材料的加入都能改善 PPS 的冲击强度和破坏韧性。不同共混(加入)方法对 PSF/PPS 与 PEK/-C/PPS 两体系的增韧效果有影响。
The fracture toughness(G_(ic))and fracture morphology of polyphenylene suifide(PPS)toughened with high performance thermoplastic bisphenol A polysulfone(PSF),polyetherketone with cardo group(PEK-C)have been studied.Both systems showed the im-proved impact strength and fracture toughness of PPS.The toughened effect has been affectedby the method of blend.
