Summary: Digital image and volume correlation (DIC and DVC) are used to measure the deformation and damage behavior of composite materials. The heterogeneous nature of the composite microstructure results in complex local behavior that cannot be captured using traditional techniques. DIC and DVC offer significant advantages in monitoring this behavior for fiber-reinforced composite materials. The careful consideration of testing setup and approach is crucial for achieving accurate results.

Summary: Recent trends in miniaturisation and high-strength fibrous composites have led to the use of mechanical microdrilling technology in fibre-reinforced polymer composites (FRPs). However, the size effect presents challenges in directly applying prior knowledge on FRP machinability to micro-drilling. The present study comprehensively reviews the challenges, recent experience, and future aspects of mechanical micro-drilling of glass and carbon fibre reinforced polymer (GFRP, CFRP) composites, including chip removal mechanisms, geometrical defects, cutting energetics, and future research directions.

Summary: This study examines the mechanical response and failure behavior of a hybrid joint fastened using multiple micro-bolts subjected to quasi-static tensile loading numerically and experimentally. The hybrid joint fastened using a single standard bolt and only adhesively bonded joint configuration are also evaluated for a comparative purpose. The experimental analysis shows that the hybrid joint fastened using micro-bolts deformed greater at the peak load before the adhesive layer got disbanded, thereby demonstrating a greater fatigue life with gradual stiffness degradation behavior as compared to the other two joint configurations.

Summary: This study proposed a new approach based on the 3D discrete element method (DEM) to simulate the progressive delamination in unidirectional carbon fibre reinforced polymer (CFRP) composite laminates. A hexagonal packing strategy was used for modelling 0 degrees representative plies, and the interface between different plies was modelled with one bond and seven bonds following the conservation of energy principle and a power law. DEM simulations of delamination with both interface models were conducted on unidirectional composites for double cantilever beam (DCB), end-loaded split (ELS), and fixed-ratio mixed-mode (FRMM) tests. The seven-bond interface model showed better agreement with experimental data in all three tests, indicating its superiority in accurately simulating the progressive delamination process.

Summary: In recent decades, there have been various attempts to numerically model fibre-reinforced polymer (FRP) composites in aerospace, auto, and marine sectors due to their excellent mechanical properties. However, accurately predicting the failure of these composites remains challenging due to their anisotropic and inhomogeneous characteristics, multiple failure modes, and interaction under multiaxial loading conditions. Micromechanics-based numerical models, such as representative volume elements (RVEs), have been developed to understand the progressive failure mechanisms and evaluate existing failure criteria of composites. This review paper summarizes the development of micromechanics-based RVE modelling of unidirectional (UD) FRP composites using finite element (FE) and discrete element (DE) methods, discussing fiber spatial distribution, constitutive models, periodic boundary conditions, progressive failure mechanisms, and comparison with classical failure criteria.

Summary: The objective of this study is to develop a fully continuous operation for separations based on diafiltration using semipermeable nanofiltration or ultrafiltration membranes. A continuous spatially distributed diafiltration (CSDD) operation is developed to achieve continuous single stage diafiltration with equivalent or better purification efficiency than batch and incumbent continuous diafiltration configurations. By introducing a diafiltration solvent spatially across the membrane unit in a highly uniform manner using 3D-printed static mixers, CSDD improves solvent consumption and yield compared to batch diafiltration. CSDD may serve as an attractive intermediate purification and solvent swap operation for telescoped flow chemical and continuous processing applications.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.
