摘要： 热塑性、耐高温的工程塑料聚醚醚酮(PEEK)是一种半晶聚合物.用碳纤维(CF)增强PEEK可明显改善其力学性能和耐热性,研究了PEEK的Tg转变以及相应的主转变内耗峰(a)峰的峰形,峰位在不同碳纤维含量下的变化.我们用DMA, DSC研究了PEEK及其复合物的转变行为.

关键词: PEEK, 碳纤维复合材料, 内耗, Tg

Abstract: The dynamic mechanical behavior of poly(ether ether ketone)(PEEK) mixedwith carbon fibre(CF)has been investigated from room temperature to 250℃,Two internalfriction peaks(α peak and α' peak) have been found in this temperature range.The experi-ments show that α peak relates to a relaxation course in which glasslike state transforms torubberlike state and peak α' relates to a pre-melting course,PEEK specimens containing dif-ferent CF content show different behavior for both α and α'peaks.DSC tests give out thesame results as the dvnamic mechanical measurements.

Key words: PEEK, CF, internal friction, Tg
