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 ...

Manufacturing and testing of a cruciform coupon for biaxial transverse tests
(International Committee on Composite Materials, 2015)
The present study deals with the manufacturing of cruciform coupons to be tested under tensile biaxial transverse loads. The objective is to obtain a geometry that minimizes the effect of stress concentrations, maximizes ...

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 ...
