“…La resistencia de una parte está ligada no solo al fallo de la primera capa, sino a la evolución que presenta el daño al propagarse por las diferentes capas o láminas de material compuesto [89]. El análisis del daño progresivo ha sido empleado en materiales compuestos con manufactura tradicional para predecir este fenómeno.…”

La fabricación aditiva (AM),y más específicamente la impresión 3D,ha comenzado una revolución de la industria de la manufactura al proporcionar capacidades de producción para piezas que eran imposibles de fabricarhace algunos años. Una tecnología bastante reciente,desarrollada porMarkforged,ha elevado estas capacidades a un nuevo nivel al permitir la impresión de compuestos de matriz polimérica con refuerzo continuo de fibra. Sin embargo, por ser este un método nuevode fabricación, no existe un modelo consolidado para predecir las características mecánicas ni los modos de falla que presentan al estar sometidas a cargas. El presente trabajo recoge los estudios sobreel daño y falla progresiva en materiales compuestos de fibras largas producidos por manufactura aditiva

“…Slow crack growth was observed in both reinforced and unreinforced polypropylene block copolymer pipes. On the other hand, Estrada et al 35 used the finite element method to investigate the effect of the boundary condition on the first ply failure and stress distribution of a multilayer composite pipe.…”

Advances in technology have provided fresh generations of stiff polypropylene block copolymers for gravity sewerage applications. The aim of this study is to further enhance the stiffness of these materials through the incorporation of inorganic fillers. In this study, three talc filled PP and one glass fiber filled PP composites were characterized in order to be used as a middle layer in a threelayer sewage pipe. The obtained results showed an increase of approximately more than 100% and 250% in tensile and flexural moduli by the use of 30%-50 wt% talc-filled PP and 30 wt.% glass fiber-filled PP, respectively. This high increase in the rigidity of the material would allow manufacturing pipes with improving ring stiffness. Composites filled with 30 wt% talc or glass fiber showed good filler-matrix interaction and good filler distribution and dispersion. However, reduced filler-matrix interaction was observed in the case of the composite filled with 50 wt% talc. In addition, the use of Differential Scanning Calorimetry analysis revealed that the addition of fillers enhanced the crystallization temperature of the polypropylene matrix. Furthermore, Thermogravimetric Analysis showed that the high modulus PP grade retained its thermal stability in the various composites.
