Summary: This study examined the properties of epoxy composites with dendritic copper particles and found that the addition of copper particles improved the electrical conductivity and mechanical properties of the composites. The glass transition temperature of the composites could be adjusted by varying the copper particle ratio. The study also evaluated the shielding properties of epoxy-based composites against gamma radiation and found that the addition of copper particles significantly altered the microstructure and mechanical properties of the composites.

Summary: In this study, the researchers investigated the effects of filler compounding, filler surface treatment, and liquid crystal structure on the properties of epoxy resin (EP) and liquid crystal epoxy resin (LCEP) composites. They found that the composite with 45 μm and 3 μm Al2O3 compound fillers at a ratio of 3:2 showed improved viscosity and thermal conductivity compared to other composites with different filler sizes and ratios. The filler surface treatment with a silane coupling agent also enhanced the properties of the composites.

Summary: In this research, radiation-shielding composites were prepared using natural rubber as a matrix and different particle size powders, including tungsten, tungsten trioxide, and tungsten carbide, as fillers. The results showed that the composite material 50 WC/NR had significantly higher linear attenuation coefficients for both X-rays and gamma-rays compared to natural rubber. Additionally, 50 WC/NR exhibited superior elongation at break and lower hardness. Therefore, it can be considered as an alternative to lead-containing radiation-shielding materials and has promising application prospects.

Summary: This study presents a new fast isostatic hot pressing method for fabricating W-Cu composites with nanosized grain boundaries and high effective density. The microstructure analysis shows that the samples have a polycrystalline well-packed structure, with copper acting as a matrix surrounding the tungsten grains. The W-Cu composites exhibit high shielding efficiency against gamma radiation in the 0.276-1.25 MeV energy range, making them excellent materials for radiation protection.

Summary: This study investigated hygrothermal aging in two particle-filled epoxy-based composites. The composites had comparable filler loadings but differed in filler type (portland cement; quartz). The influence of 10 different climates with varying humidities and temperatures on mechanical properties was examined periodically using tensile tests. The changes in structure and composition were analyzed through microscopy, EDX, TGA, and XRD. It was found that physical aging and the growth of crystals within cement fillers contributed to stiffening effects, while water uptake led to an increase in modulus due to the formation of hydration products. The degradation of Young's modulus was not affected by filler type, but the degradation of tensile strength was substantially influenced.

Summary: Fiber-reinforced polymer (FRP) composite materials are versatile due to their high specific stiffness and strength, but their brittle nature limits their properties. Adding nanoparticles as fillers in FRP composites can overcome these limitations. This paper focuses on studying the effect of nanofillers on the mechanical behavior of glass/epoxy composites.

Summary: Preventing high-energetic nuclear radiation photons is a significant concern. Many studies have been conducted to find alternative materials to lead, including a novel shield design of alloys formed by the combination of W, La and Bi. The photon shielding performances of these investigated alloys were studied using Monte Carlo GEANT4 simulation code and XCOM computer software. The results show that the W-3 alloy has better shielding performance compared to Pb and OC materials.

Summary: This study focuses on the preparation of B4C dispersed epoxy composites for irradiation shielding applications. Samples of different compositions were made and subjected to thermal characterization and irradiation attenuation studies. The results show that the thermal stability of the samples increased due to the intrinsic conductivity of the filler particles, while the shielding performance of the samples increased with an increased addition of B4C at lower energies due to photoelectric absorption.

Summary: The nitrogen-doped graphene synthesized in this study showed increased electromagnetic interference shielding efficiency compared to other carbon nanomaterials and composites, mainly due to the high specific surface area of the filler and the presence of nitrogen acting as polarizing centers. This makes N-GP/epoxy composites an excellent material choice for EM shielding applications.
