An experimental characterization of the acoustic fatigue endurance of GLARE and comparison with that of CFRP

Damage mechanisms have been observed and fatigue data established. Using these experimental data, surface strain versus number of cycles to failure curves have been established. In particular, this work has assessed the behaviour of GLARE in bending and has highlighted the importance of the lay-up sequence for the “fibre bridging effect” on crack propagation to be effective.
