“…When compared to the pure polymer prints, the strength, stiffness, fatigue and corrosion resistance and damage tolerance of FRCs are considerably higher [ 125 ]. These mechanical properties can be further enhanced by employing the most suitable raster angle, layer thickness, infill pattern, number of reinforced layers, extrusion temperature of the filament, airgap, diameter of the filament, the time between adjacent layer deposition and the conditioning temperature [ 131 , 132 , 133 , 134 , 135 , 136 ].…”

Fused deposition modelling (FDM) is one of the fastest-growing additive manufacturing methods used in printing fibre-reinforced composites (FRC). The performances of the resulting printed parts are limited compared to those by other manufacturing methods due to their inherent defects. Hence, the effort to develop treatment methods to overcome these drawbacks has accelerated during the past few years. The main focus of this study is to review the impact of those defects on the mechanical performance of FRC and therefore to discuss the available treatment methods to eliminate or minimize them in order to enhance the functional properties of the printed parts. As FRC is a combination of polymer matrix material and continuous or short reinforcing fibres, this review will thoroughly discuss both thermoplastic polymers and FRCs printed via FDM technology, including the effect of printing parameters such as layer thickness, infill pattern, raster angle and fibre orientation. The most common defects on printed parts, in particular, the void formation, surface roughness and poor bonding between fibre and matrix, are explored. An inclusive discussion on the effectiveness of chemical, laser, heat and ultrasound treatments to minimize these drawbacks is provided by this review.

Además, presentaron imágenes de microscopía electrónica en donde se evidencian los mecanismos de daño de compresión como la delaminación por pandeo, fractura de fibras y bandas de pliegue, como se muestra en la Figura 4.…”

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

“…Temperature effects were also analyzed by [14]- [16], leading to a closer approximation between experimental values and theoretical predictions for the critical and ultimate loads of cylindrical members. It is well known that the compressive strength of structural members can be increased by using longitudinal and inner stiffeners [17]- [19]. When a riser integrity assessment indicates a premature failure, the situation is usually solved by welding longitudinal stiffeners at the bottom.…”

This work presents the finite element analysis of partially stiffened cylinders subjected to axial compression at elevated temperatures. The compressive strength is calculated for self-weight conditions and the influence of the temperature on the material response is also investigated. In the oil industry, pressure vessels are commonly used operating at complex design conditions such as high-pressure profiles and/or elevated temperature gradients which affect considerably the structural response of inner components. Among them, risers become sensitive steel elements withstanding heavy compressive loading due to self-weight, as well as, insulation elements added toprotect them from the elevated temperature gradient. Most risers structurally fail at the bottom end due to buckling caused by self-weight and temperature effects. To remediate this situation and to guarantee the integrity of the riser, longitudinal stiffeners are welded at the bottom end. Hence, a proper determination of the compressive strength of the cylinder, taking into account the influence of the longitudinal stiffening and the corresponding temperature, is required.Results indicate that the use oflongitudinal stiffeners in deformed cylinders increases the strength to buckling in percentages that vary according to the cross-section of the profiles.
