高温热塑性树脂基复合材料的断裂行为

TENSILE FRACTURE BEHAVIOR OF GRAPHITE COMPOSITE LAMINATES WITH THERMOPLASTIC MATRIX

摘要

摘要: 本文研究了碳纤维增强高温热塑性塑料(PEEK)基复合材料的断裂行为.发现其强度极限没缺口断裂应力均高于同种纤维增强的热固性(环氧)树脂基材料,并且随0°叠层含量的增加,二者之间的差距加大.另外,前者比后者缺口敏感性低,断裂韧性高.

Abstract: A study was conducted to the tensile fracture behavior of graphite composite laminates with thermoplastic matrix. The results show that undamaged ultimate tensile strengths and damaged fracture stress of the laminates with thermoplastic matrix (PEEK) are higher than that of the ores with epoxy matrix for the same configuration,and the difference between them becomes greater with the increacement of the percentage of 0°-layers,and the notch sensitivity is lower and the fracture toughness is higher for graphite/hermopIastic(AS₄/PEEK),as compared with the graphite/epoxy (AS₄/3501)laminates.
