Summary: By designing a double-layer interface, the interfacial incompatibility of carbon fiber reinforced magnesium matrix composites was overcome, resulting in increased tensile strength and toughness of the material. The ZrO2-MgO interface not only inhibited Al4C3 to prevent fiber damage, but also improved wettability, leading to significant improvements in mechanical properties.

Summary: In this study, CF/Al composites with different weight fractions and surface modifications were fabricated using a hot coining technique, revealing that Cu-coated CF samples exhibited superior microstructure and mechanical properties compared to uncoated samples. Uncoated CF/Al composites showed significant improvements in microhardness and wear properties at 10% CF, but a decrease in compressive strength at 20% CF. The results suggest that surface modification of CF can enhance the microstructure and mechanical properties of CF/Al composites.

Summary: This study used ultrasonic soldering to join carbon fiber reinforced aluminum matrix composites (Cf/Al) and found that wetting could be achieved within 5 seconds. The wetted carbon fiber surface was observed to have an amorphous-nanocrystalline layer, formed due to the high velocity, temperature, and pressure caused by cavitation. Limited carbon fibers flowed into the joint at low ultrasonic power, while a fully carbon fiber reinforced composite joint was obtained at higher power. The soldered joints had higher strength than the Cf/Al substrate, and the formation mechanism was discussed.

Summary: This paper evaluates the anti-icing properties of samples treated with PEO followed by application of SPTFE and PVDF. The combined PVDF-SPTFE coating shows superior electrochemical characteristics, hydrophobicity, and icephobic properties. The decrease in ice adhesion strength after treatment with PVDF-SPTFE is significant, making it a promising solution for anti-icing applications.

Summary: During the sintering process, the orientation of short carbon fiber changes with the pressure direction, significantly affecting the mechanical and wear performance of Cf(Ni)-ZrC/2024Al composites. The composite parallel to the carbon fiber plane (Cf(Ni)-ZrC/2024Al-P) exhibits increased elastic modulus, tensile strength, and strain compared to the composite vertical to the carbon fiber plane (Cf(Ni)-ZrC/2024Al-V). The wear rate of Cf(Ni)-ZrC/2024Al-P is higher than that of Cf(Ni)-ZrC/2024Al-V, but it has less anti-friction properties.

Summary: In this study, a micro-mechanical investigation was conducted on cold-drawn reduced graphene oxide (RGO) reinforced aluminum (Al) composite wires. The results showed that the composite wires exhibited superior mechanical properties compared to unreinforced Al sample over the entire temperature range. This was attributed to the effective grain growth inhibition achieved by RGO via grain boundary pinning. The RGO-Al composite wires demonstrated higher strength, heat resistance, and ease of fabrication, making them a promising alternative to conventional HT Al alloy-based conductors.

The principal damage mechanism was strain localization in the CGs.

Summary: Modern composite materials typically consist of at least two components, with the microstructure playing a critical role. The way weak materials are coated in different types of composites can impact the fracture toughness of the materials. In some biological ceramic materials, organic weak materials serve multiple roles.

Summary: A new fabrication route for reinforcing titanium with carbon fibers is proposed by using an intermediate matrix with a sufficiently low melting point. The carbon fiber/intermediate matrix layers serve as reinforcing components for the titanium, acting as the main matrix. Bending tests of the composite specimens demonstrate the possibility of obtaining composites with strength and Young's modulus values of at least 1000 MPa and 160 GPa, respectively, which are significantly higher than those of the main matrix.

Summary: The effect of compaction modes on the microstructure, properties, and fracture nature of a carbon-aluminum composite wire preform was investigated. The results demonstrated that the increase in temperature, load, and holding time resulted in a decrease in pore volume fraction and an increase in fiber fraction, leading to enhanced composite strength. The fracture surface morphology indicated the brittle nature of the composite fracture in all cases.

Summary: The study investigated the effect of infiltration time on the infiltrated volume of a carbon fiber yarn in an aluminum melt under cavitation. Results showed that longer infiltration time led to complete infiltration, while shorter time resulted in decreased infiltrated volume. The infiltration rate was estimated to be 20.9 cm³/s, independent of infiltration depth. The pressure required for complete infiltration was calculated to be approximately 270 Pa, with negligible difference between values from Darcy's and Forchheimer's laws, suggesting the use of a simpler Darcy's law for pressure estimation.

Summary: The research focuses on carbon fiber oxide coatings in metal matrix composites, where the sol-gel method alone does not allow for control of carbon fiber coating thickness. A combined method of sol-gel technology and electrochemical deposition has been used to produce SiO2 coatings on carbon fibers, with the study exploring the effects of various parameters on the coatings' structure and thickness.
