Summary: The mesoscopic model of fibre-reinforced composites provides important geometric and material information for predicting the mechanical properties of composite components. A method to build a mesoscale preform of a plain-weave composite component with complex geometry using parameterisation and integration was established in this study. The credibility of this method was verified through similar microscopic observations and experiments in other studies, and its applicability to more complex components was also investigated.

Summary: The study presents a structured fabric with tunable bending modulus made up of three-dimensional particles arranged into layered chain mails. When pressure is applied at their boundaries, the particles interlock and jam the chain mails, resulting in a dramatic increase in bending resistance. This property is due to the high tensile resistance of the interlocking particles, providing potential for lightweight, tunable and adaptive fabrics for various applications.

Summary: In this paper, a nonlinear hyperelastic constitutive model is proposed and implemented to capture the forming behavior of fabrics. The model considers biaxial coupling and normal-shear coupling of the interwoven fiber bundles in a woven fabric. The influence of these couplings on the forming result is investigated through forming studies on a generic double dome geometry.

Summary: C-sandwich radome composites with double-layer woven lattice truss composites were designed and manufactured. Edgewise compressive testing revealed that the failure mechanism depends on the panel height, with global buckling, core piles fracture, and skin fracture being the typical failure modes. The global buckling is induced by the shear failure of the truss core, which is restricted with shorter columns. This study provides guidance for the design and preparation of radome sandwich composites.

Summary: The study investigated the effect of inter-ply sliding on multi-ply NCF preforms during the DDF process, and found that wrinkles were most severe when the inter-ply angle was 45 degrees, with wrinkle length being related to the relative fibre angle. Experiments confirmed that out-of-plane wrinkles are sensitive to the friction resistance between NCF plies, and lubricating the fibres can minimize wrinkling defects caused by dissimilar inter-ply deformation.

Summary: This paper discusses the influence of multiple impacts on the compression strength of honeycomb sandwich structures with composite face sheets. It is found that the size of the impactor affects the turning point of the compression strength. Additionally, high impact energy leads to damage in the bottom face sheet and reduces the overall compression strength.

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.

Summary: Real-time monitoring of carbon fibre composites during Automated Fibre Placement (AFP) manufacturing remains a challenge for non-destructive evaluation (NDE) techniques. This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
