Delamination Propagation

The delamination at the interface between the aluminium and prepreg layers has greater influence on the fatigue crack growth in fiber metal laminates. To study delamination propagation property of one kind of new fiber metal laminates, by using 2/1 lay-up specimen, this article accomplished delamination propagation test under various stress levels at R=0.1 by optical method and compliance method respectively. The delamination propagation property of this laminate is obtained by analyzing and calculating. A modified compliance equation is created to calculate the delamination size of this laminate more accurately by adding a non-dimensional factor.

Bending Loading

A special open-hole sheet specimen of GLARE fiber-metal laminate was used to simulate mixed loading similar to the loading of a riveted hole in a real fuselage skin structure. The effect of cyclic tension and secondary bending loading was studied. The notch region was observed through a microscope in order to detect the first fatigue crack initiation during fatigue loading. The number of cycles prior to crack initiation was measured, and the crack growth rate in the surface layer of the laminate was evaluated. The specimens were subjected to fatigue damage investigation in the inner layers of the laminate after termination of the test. A significant effect of secondary bending on fatigue crack initiation and early crack growth was found. The experimental results are discussed in terms of local stress-strain conditions in the notch region evaluated by means of finite element calculation.
