Fatigue Resistance of Composite Fibre-metal Laminates Subjected to Impact Loading
نویسنده
چکیده
GLARE (GLAss REinforced) belongs to a family of fibre-metal laminates currently being used as a skin material for the upper and side shells in the forward and rear fuselage body of A380. This composite material consists of thin layers of aluminium sheets and unidirectional prepreg layers of glass fibres embedded into an epoxy based matrix. GLARE demonstrates excellent resistance to fatigue crack growth, high tolerance to accidental damage, and superior residual strength in comparison with monolithic aerospace aluminium alloys used for structural applications. Significant research into the impact behaviour of fibre-metal laminates has been documented in the literature [1-4]. There has however been limited published work on the fatigue behaviour of GLARE subjected to dynamic impact loading [5,6]. Therefore, further work on the fatigue resistance of fibre-metal laminates following impact loading is strongly required. This paper presents the results of an experimental investigation into the effect of low velocity impact loading on the fatigue performance of GLARE.

In recent years, ultrasonic methods have been developed that can measure the mechanical stiffness of composites. The Lamb wave velocity is directly related to the material parameters, so an effective method exists to ascertain the stiffness of composites by measuring the velocity of these waves. In this study, a Lamb wave measurement system was used to measure the bending and out-of-plane stiff...
