Al contrario que en el caso de la configuración PHSF, en las configuraciones PHRA y PHRP, el primer pico de fuerza de la curva no corresponde con la rotura a tracción de las fibras de las pieles inferiores, sino con la rotura a compresión de las fibras de las pieles superiores tal y como se puede observar en la Figura 7a. En el caso de la configuración PHRA, la rotura a tracción de las fibras de la piel inferior se ha producido a una deformación de ensayo de 9 mm tal y como se puede ver en el gráfico de la Figura 6b, perdiendo toda capacidad de soportar carga. Sin embargo, en el caso de PHRP no se ha producido tal rotura y el ensayo ha tenido que ser parado a los 12 mm de deformación, cuando los extremos de la viga han hecho contacto con la parte superior del utillaje de flexión, aun con capacidad de soportar la carga aplicada. En la Figura 7b se puede ver la rotura a tracción de la piel inferior de la configuración PHRA y una separación total de la intercara entre los anillos de carbono del núcleo debido a la cortadura. Por el contrario, en la misma imagen se observa que en la configuración PHRP no ha habido tales fallos y que el núcleo reforzado perimetralmente no ha sufrido roturas catastróficas debido a la continuidad de las fibras de refuerzo a lo largo de toda la viga. Por último, cabe destacar que el refuerzo del núcleo tanto con la estrategia de anillos o de forma perimetral ha resultado en el aumento de la rigidez de la viga hasta en un 25% (Tabla 4) en comparación con la misma configuración cuyo núcleo ha sido fabricado sin refuerzo de carbono.</div></td><td class='diff-marker'> </td><td style="background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;"><div>Por lo que respecta a las configuraciones con los núcleos reforzados, en la Figura 6b se muestran los resultados obtenidos de los ensayos de flexión en comparación con la configuración previamente discutida PHSF, que ha sido fabricada siguiendo la misma estrategia, pero sin reforzar el núcleo, y así poder analizar el efecto del refuerzo en el núcleo.

<br />
Additive manufacturing with FFF (Fused Filament Fabrication) technology using continuous fibre, allows more complex structure designs with more technical materials than conventional manufacturing processes. The present paper is focused on analysing the bending behaviour of sandwich beams with unidirectional carbon fibre skins and honeycomb type core. The nobelty of the research is focused on printed materials (polyamide 6 reinforced with continuous carbon fibres) and the fact that the core has been manufactured directly in the printig process. The study variable consisted of the spatial arrangement of the beam; for the first type of beams the skins are positioned in parallel with the base plate, whereas for the second type of beams, the skins are placed perpendicullary with respect to the base plate. Thus, in both cases skins are obtained with the same fibre orientation, but with different manufacturing strategies. Otherwise, those configurations where skins are placed in parallel with respect to the base plate, the influence of reinforcing the hexagons of the core with carbon fibres following different strategies has been analysed. On the one hand, the hexagons are reinforced depositing continous carbon fibre following concentric deposition strategy, forming hexagonal rings in each hexagon independently. On the other hand, the overall core is reinforced toghether with continous carbon fibres following the external perimeter of the core. Results show that the beams whose skins have been manufactured in parallel with respect to the base plate have higher stiffness. In the same way, those structures with reinforced cores have a higher stiffnes compared to those with non-reinforced cores.<br />
