Summary: By dispersing reduced graphene oxide (RGO) and alumina into the epoxy matrix at different hybrid ratios, the synergy of RGO and alumina at 6:4 was found to enhance thermal conductivity by 23.4%, retain insulation properties, increase tensile strength, and improve storage modulus. The settling of alumina nanoparticles on the graphene surface inhibits electron transfer and eliminates graphene agglomerations, making it an important study for designing optimal multi-functional polymeric packaging materials.

Summary: This study reviews the effect of nano-additives on improving the mechanical properties of composites. Nano-additives, also known as nano-composites, have promising applications in various fields. They can significantly alter thermal conductivity, tensile strength, flexural strength, fatigue strength, impact resistance, vibration resistance, buckling, post-buckling, and surface modification of nanoparticles in composite materials. Recent findings suggest that the addition of nanoparticles can reduce delamination and enhance vibration behavior and energy absorption capacity. Additionally, machine learning techniques have shown potential for improving mechanical properties and reducing fabrication costs.

Summary: The purpose of this study is to prepare nano-TiCp reinforced Al-13Si-5Cu-2Ni matrix composites by self-propagating high-temperature synthesis (SHS), study the changes in microstructure and mechanical properties, and summarize the strengthening mechanism. The results show that the addition of nano-TiCp can significantly improve the nucleation rate of alpha-Al phase and refine alpha-Al dendrites. The size of precipitated phases Al2Cu is also refined by 28.1% and more evenly distributed. The tensile strength, yield strength, and elongation of the alloy with 1 wt% nano-TiCp are increased by 5.7%, 6.5%, and 29% compared with the alloys without nano-TiCp. This work provides a reference for enhancing the properties of Al alloys with nano-particles to achieve microstructure refinement and performance improvement.

Summary: The mechanical, thermal, and electrical properties of porous SiC ceramics can be independently tuned by selecting the appropriate starting particle size and sintering atmosphere. In the porosity range of 40% to 54%, the compressive strength and thermal conductivity of porous SiC ceramics increased as the porosity increased, contrary to the general trend. Additionally, the electrical conductivity of porous SiC ceramics sintered in N-2 atmosphere was significantly higher compared to those sintered in Ar atmosphere due to N doping in the PCS-derived beta-SiC.
