摘要：
An experimental study was conducted to examine the influence of cyclic loading on the interfacial properties of carbon fibre/epoxy resin composites. Two composite material systems having the same fibres and epoxy matrix, but with different fibre surface treatments, oxidised/sized and untreated, respectively, were used in this study. The existence of different interphases in these materials was studied using dynamic mechanical analysis (DMA) techniques. Fatigue tests were conducted at various load levels and then by using DMA and C-scan techniques, the fibre/matrix interfacial degradation was characterised. The results indicated that cyclic fatigue loading did affect the fibre/matrix interfacial properties of the composite laminates. Specimens with oxidised/sized fibres showed less interfacial degradation compared to laminates with untreated fibres. (C) 2002 Elsevier Science Ltd. All rights reserved.
