Summary: This study proposes a new composite fastener that enhances the bearing strength of composite joints by using a nano-coating on the thread and embedding a magnet in the shank. A physics-guided neural network accurately predicts the real stress situation of the joints. Compared to traditional metallic fasteners, this new fastener reduces the weight of composite structures and monitors the health of the structures.

Summary: High flexural strength is crucial for a ceramic armor component to withstand high tensile stresses and multiple hits, as it helps protect the structural integrity. The study examined the effect of different ZrO2 content on the flexural strength of Al2O3-ZrO2 composites, and found that the composite with 20% ZrO2 had the highest strength.

Summary: This study focused on blending coal discard with a polysiloxane preceramic polymer resin to produce coal/ceramic composites, then evaluating their physicomechanical properties. The results showed that functional groups in the coal discard promoted bonding with the polymer, leading to composites with low water absorption and high flexural strength. More tests are needed to fully characterize the properties of the coal composites.

Summary: The study investigates the relationship between the thickness and flexural strengths of laminar carbon fibre reinforced polymer (CFRP) plates through experimental and analytical methods. A simple composite formula is used to link the thickness effect to the ply thickness. Different sample thicknesses are tested, and the flexural strengths are evaluated and modeled using the Strength of Materials (SOM) formula and the simple composite formula. The ASTM standard D7264 is justified analytically, suggesting that a thickness of 4 mm is sufficient for CFRP plates with typical ply thicknesses around 120-130 μm.

Summary: CaO-B2O3-SiO2/Al2O3/SiO2 composites were developed for LTCC applications, and their sintering behavior, phase compositions, microstructure, dielectric properties, and mechanical properties were investigated. The results showed that an appropriate amount of silica could reduce the dielectric constant and improve the dielectric properties of the composite material. The CBS/Al2O3/SiO2 glass ceramics with 32 wt% Al2O3 and 16 wt% SiO2 achieved excellent comprehensive performance and matched well with the silver electrode, making it a highly promising material for LTCC applications.

Summary: In this research, the structural, microstructural, optical and electrical properties of CuO/ZnO nanoparticle/nanorod composites in PVA matrix were investigated using a two-step sol-gel technique. The synthesized samples were characterized using X-ray diffraction, Field Emission Scanning Electron Microscopy, Energy Dispersive X-ray analysis, UV-visible spectroscopy, and an LCR meter. The results confirmed the crystalline properties of CuO and ZnO metal oxides in the PVA matrix and analyzed the optical and electrical behaviors of the composites.

Summary: In this study, we aimed to improve the mechanical strength and durability of photosensitive resins (PSR) by using TiO2 nanoparticles. Our experimental results show that larger nanoparticles decrease the mechanical durability of PSR, while reducing the size of nanoparticles to 20 nm increases mechanical resilience, leading to improved flexural and tensile strength of PSR.

Summary: The mechanical properties of thermally stable ultrafine-grained Al metal matrix composites dispersion strengthened and stabilized by nano-metric in-situ Al2O3 were tested by small punch testing (SPT) across a range of temperatures. The microstructural features of the materials had a significant impact on their mechanical properties and the correlation between SPT and conventional tensile testing results varied with testing temperature. Fracture mechanisms were found to change from ductile to brittle behavior as testing temperature increased.

Summary: The research focuses on characterizing the mechanical properties and morphology of polyester/coconut shell powder composites filled with corn husk fibre (CHF). Results show that increasing CHF content leads to higher flexural strength but lower tensile strength of the composite. The enhancement of the interfacial bonding between CHF-CSP-polyester and the reduction of fiber pull-outs contribute to the improved properties.

Summary: The study investigated the tribological performance of woven carbon-carbon and carbon-carbon-silicon carbide composites treated with brake oil. The results indicated that C/C composites are more affected by brake oil compared to C/C-SiC composites. It was challenging to predict the wear and friction behavior of laminated composites in low conformity contacts.

Summary: The study analyzed the mechanical properties of epoxy-based glass fiber (GF) and carbon fiber (CF) reinforced laminated composites with the incorporation of annealed nanodiamonds (NDs) in the epoxy matrix. The addition of 0.3 wt.% NDs into the epoxy matrix led to significant improvements in tensile strength, tensile modulus, flexural strength, and flexural modulus for both GF- and CF-reinforced hybrid composites. The enhanced properties of the hybrid composites were attributed to the efficient dispersion of NDs in the epoxy matrix, facilitated by mechanical interlocking and weak Van der Waals force between the NDs particles, as reported in the study.

Summary: In this research, alumina and graphene nanoplatelets were uniformly dispersed in epoxy resin using sonication and ball milling. The physical, flexural, and dynamic mechanical properties of the epoxy nanocomposites were investigated. The addition of 2% alumina and 0.5% graphene nanoplatelets significantly improved the flexural strength and modulus of the epoxy. Scanning electron microscopy images showed the dispersion of the fillers, which was the main reason for the enhancement of flexural properties. Therefore, these nanocomposites are suitable for electrical and electronic packaging applications.

Summary: This study demonstrates the flexural strength, compressive strength, and impact energy behavior of cement-based CFRP composites loaded with graphene nanoplates and fly ash microparticles. The addition of graphene nanoparticles and microparticles enhances the mechanical properties, including compressive strength, flexural strength, impact energy, and fracture toughness. These findings suggest that nano/microparticle-filled carbon fiber and glass fiber reinforced epoxy resin composites have potential applications in seismic wave resistance due to their improved mechanical properties.

Summary: In this work, the surface of nanodiamonds (NDs) was modified to remove carbon content and noncarboneous particles, resulting in improved nanohardness and viscoelastic response when incorporated with an epoxy matrix. The study also investigated the surface morphology and crystalline nature of NDs/epoxy composites. Nanohardness and nano-dynamic mechanical analysis (DMA) tests were conducted, showing significant improvements in young's modulus and storage modulus with increasing ND concentration. The composites also exhibited higher tan delta values and phase lag in the tan delta curves compared to neat epoxy, making them suitable for automotive and aerospace applications.
