Effects of debonding length on the fatigue and vibration behaviour of sandwich composite

Abstract : The aim of this study is to investigate the effects of debonding length on the fatigue and vibration behaviour of sandwich material. The sandwich material used in this study is constructed with glass fibre laminates as skins and with PVC closed-cell foams as core. The tests were conducted using impulse frequency response technique and cyclic fatigue loading in three-point bending with various debonding lengths. The vibration test was used to study the effects of debonding length on modal parameters (frequency, loss factor). The effects of debonding lengths on the stiffness, hysteresis loops and damping were studied during fatigue tests. The different relative change in frequency, loss factor and maximum load is determined. These parameters are compared for vibration and fatigue tests.
