Defect detection in 3D printed carbon fibre composites using X-ray Computed Tomography

Defect detection in 3D printed carbon fibre composites using X-ray Computed Tomography

X-ray Computed Tomography (X-ray CT) has become a vital tool for product quality inspection. The X-ray CT analysis of 3D printed composites, with a layer-by-layer structure of carbon fibre/polyamide and polyamide plies, demonstrates how the void content increases with an increasing number of consecutive carbon fibre layers. Not only the void content, but also the pore
network complexity increases, as more pore types are introduced into the sample. The PolyAmide (PA) matrix has an averag... Read more

Modelling deformation and fracture in confectionery wafers

Modelling deformation and fracture in confectionery wafers

The aim of this research is to model the deformation and fracture behaviour of brittle wafers often used in chocolate confectionery products.

Three point bending and compression experiments were performed on beam and circular disc samples respectively to determine the ‘apparent’ stress-strain curves in bending and compression. The deformation of the wafer for both these testing types was observed in-situ within an SEM. The wafer is modelled analytically and numerically as a composi... Read more

Damage Evaluation in Woven Glass Reinforced Polyamide 6.6/6 Composites Using Ultrasound Phase-Shift Analysis and X-ray Tomography

Damage Evaluation in Woven Glass Reinforced Polyamide 6.6/6 Composites Using Ultrasound Phase-Shift Analysis and X-ray Tomography

The paper proposes a new experimental methodology, based on ultrasonic measurements, that aims at evaluating the anisotropic damage in woven semi-crystalline polymer composites through new damage indicators. Due to their microstructure, woven composite materials are characterized by an anisotropic evolution of damage induced by different damage mechanisms occurring at the micro or mesoscopic scales. In this work, these damage modes in polyamide 6.6/6-woven glass fiber reinforced composites ha... Read more

Metal-Organic Framework Crystal-Glass Composites

Metal-Organic Framework Crystal-Glass Composites

The majority of research into metal-organic frameworks (MOFs) focuses on their crystalline nature. However, in recent research the vitrification of a number of MOFs has been revealed. We propose that the solid-liquid phase transitions involved in MOF-glass formation can provide unique opportunities for the creation of a new class of functional, stable and porous composite materials. Described herein is the design, synthesis, and characterisation of novel metal-organic framework (MOF) crystal-... Read more

Advances in the Synthesis and Long‐Term Protection of Zero‐Valent Iron Nanoparticles

Advances in the Synthesis and Long‐Term Protection of Zero‐Valent Iron Nanoparticles

Core@shell Fe@Fe3O4 nanoparticles (NPs) are synthesized via the thermal decomposition of iron pentacarbonyl (Fe(CO)5) in the presence either of oleylamine (OAm) or a mixture of OAm and oleic acid (OA). The heterostructured nanocomposites formed do so by a postsynthetic modification of isolated Fe seeds. This proves the versatility of the coating procedure and represents a significant advantage over previous work with Co seeds owing to the higher magnetic susc... Read more

Impact of Pore Tortuosity on Electrode Kinetics in Lithium Battery Electrodes: Study in Directionally Freeze-Cast LiNi0.8Co0.15Al0.05O2 (NCA)

Impact of Pore Tortuosity on Electrode Kinetics in Lithium Battery Electrodes: Study in Directionally Freeze-Cast LiNi0.8Co0.15Al0.05O2 (NCA)

The prevailing electrode fabrication method for lithium-ion battery electrodes includes calendering at high pressures to densify the electrode and promote adhesion to the metal current collector.

However, this process increases the tortuosity of the pore network in the primary transport direction and imposes severe tradeoffs between electrode thickness and rate capability. With the aim of understanding the impact of pore tortuosity on electrode kinetics, and enabling cell designs with ... Read more
