Summary: The three-dimensional honeycomb woven electromagnetic absorbing composites were fabricated on an ordinary loom using carbon black/carbonyl iron powder/basalt fiber/carbon fiber/epoxy resin materials through the vacuum-assisted resin transfer molding (VARTM) process. When the thickness was 15mm, the mechanical properties and electromagnetic wave-absorbing properties of the composites showed the best match. Despite various failure modes such as brittle fracture of fiber bundle and matrix cracking, the 3-D honeycomb woven EM absorbing composites still maintained good integrity without delamination.

Summary: To avoid absorption bandwidth limitations and delamination in honeycomb composites, a three-dimensional (3D) gradient honeycomb composites were prepared using a vacuum-assisted resin transfer molding process. By altering the type of absorbing agent and honeycomb structure, the effective absorption bandwidth and/or reflection loss can be optimized, especially at specific incident angles. This work provides an adjustable method for the fabrication of microwave absorption composites, with potential applications in civilian and military sectors.

Summary: Various honeycomb preforms with different cell geometries were woven using different parameters. The specific bending load of the honeycomb structure was found to be influenced by the opening angle, cell size, wall length, and number of layers while keeping cell shape and thickness constant. The failure of the specimens was attributed to face wrinkling, localized buckling, debonding of the face sheet, and cell wall collapse.

Summary: A mesoscale fatigue progressive damage model is proposed for fatigue life prediction and failure behavior assessment of 3D woven composites, incorporating Hashin's fatigue criteria and maximum tensile/shear stress criteria. A fatigue damage evolution model based on Fang's static-load damage evolution model is developed, considering damage irreversibility and compressive crack closure effect. The results show that all predicted fatigue lives fall within a two-fold error band.

Summary: The translaminar fracture toughness of two different continuous fibre 3D printed ply architectures was evaluated using a compact tension test. The performances of a baseline 0/90 cross-ply architecture and a semi-woven 0/90 ply architecture resembling Advanced Placed Ply (AP-Ply) fabricated using automated fibre placement were compared. The experimental results showed that the laminate architecture has a slight influence on the trans-laminar fracture toughness of 3D printed carbon fibre composites, and both ply architectures exhibited a rising R curve, with the semi-woven samples showing a less pronounced curve.

Summary: Aerogels are three-dimensional nanostructures made of non-fluid colloids connected to porous networks. They are often manufactured using the sol-gel technique and drying procedures like supercritical, freeze, or ambient pressure drying. Aerogels are the lightest solid material with excellent insulation properties. However, their brittleness and porous nature make their processing and handling complex, limiting their applicability in real-world dynamic situations.

Summary: Nanoscale silica aerogels have unique properties such as large surface area, low density, and high porosity, but limited electrical and thermal conductivity. Sol-gel method for synthesis is not efficient and costly, while ambient pressure drying method using methyltrimethoxysilane shows potential for commercialization. This method produces silica aerogels with extremely low bulk density and high specific surface area, exhibiting excellent chemical absorption and recyclability for substances like organic liquids and oils.

Summary: This research focuses on the fabrication of novel textile fibre-reinforced aluminum metal matrix composites (TFRAMMC) using the friction stir processing (FSP) technique, which incorporates high-performance fibres in three forms: long, chopped, and flakes. The composites were evaluated for their tensile, flexural, and impact properties to assess their load-bearing capacity and energy absorbency. The results showed that the long fibre-reinforced composite (LFRC) exhibited the highest tensile and impact strength, surpassing even the base metal (BM). The flexural strength followed the order of flakes-reinforced composite (FRC) > LFRC > chopped fibre-reinforced composite (CFRC), with the BM having the lowest flexural rigidity. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) analysis confirmed the uniform distribution and composition of the novel composite materials produced by FSP.
