Numerical analysis of the crack paths produced by fibre–matrix interface failure in cross-ply LFRP laminates
(Elsevier, 2022-03)
The so-called matrix failure, also named inter-fibre failure, is one of the main failure mechanisms in long fibre reinforced polymers (LFRPs). This mechanism is characterized by the debonding of some fibres when transverse ...

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 ...

Damage and failure mechanisms under fatigue in long fibre composites with ultra-thin plies
(2023-07-05)
El estudio del comportamiento a fatiga de los materiales compuestos es de gran interés en el ámbito científico debido al carácter no estático de las cargas que sufre una estructura en servicio. En los últimos años, la ...

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 ...

Experimental observations of fatigue damage in cross-ply laminates using carbon/epoxy ultra-thin plies
(Elsevier, 2023-02-15)
The damage mechanisms of cross-ply laminates under fatigue loading have been deeply studied during last years. In the case of quasi-static loads the so-called scale effect has recently acquired renewed importance after the ...

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 ...

Numerical and experimental analysis of ultra-thin plies in carbon/epoxy cross-ply laminates subjected to bending after tensile cyclic loading
(Elsevier, 2023-12)
As a result of a fatigue testing campaign in cross-ply laminates with different thicknesses in the 90° ply block (conventional and ultra-thin), different cracking patterns were observed. While laminates with conventional ...

Transverse biaxial tests on long fibre reinforced composites
(Elsevier, 2022-10-01)
The study and prediction of the failure mechanisms affecting long fibre reinforced composites is a fundamental field that provides an essential knowledge for the structural design with composites. Transverse failure, ...
