Estudio experimental a fatiga de laminados unidireccionales a 90⁰
(Grupo Español de Fractura, 2021-06-08)
La vida a fatiga de laminados unidireccionales a 90⁰ (UD-90) ha sido estudiada ante distintas condiciones de carga cíclica Tracción-Tracción (R=0.1). En primer lugar, el efecto de la porosidad se ha evaluado usando dos ...

Study of the influence of stacking sequence in the failure of crossply laminates manufactured with ultra-thin plies
(Asociación Española de Materiales Compuestos (AEMAC), 2024-01)
Numerous studies on the use of laminates manufactured with ultra-thin composite laminates have shown the existence of a significant delay in the appearance of damage, a phenomenon known as the Scale Effect. To study the ...

Experimental study of the use of ultra-thin plies in quasi-isotropic laminates under cyclic tension after impact
(Asociación Española de Materiales Compuestos (AEMAC), 2024-01)
In this work, the authors propose an experimental study on the possible improvement of the mechanical behaviour produced by ultra-thin plies in laminates subjected to cyclic loading after impact. More specifically, this ...

Behaviour of fibre/matrix interface cracks under biaxial stress state caused by edge effect in carbon/epoxy laminates
(Asociación Española de Materiales Compuestos (AEMAC), 2024-01)
A recent study about the ''edge effect'' phenomenon in cross-ply laminates made of ultrathin plies composites has shown the presence of a relevant stress component through the laminate thickness. This fact implies that ...

Experimental assessment of fatigue damage mechanisms in [04/90n]s laminates using carbon-epoxy ultrathin plies
(2021-06-25)
The damage mechanisms of cross-ply laminates under fatigue loading have been deeply studied during last years. In this work, the experimental assessment of two different cross-ply laminates under T-T loading (stress ratio ...

Development of a prototype test system for certification of curved fuselage panels
(IOP Publishing Ltd, 2021-01)
A prototype test system with capacity to reproduce combined loads representative of real loading cases of a curved fuselage panel has been developed. This prototype test system allows the structural validation of curved ...
