Advanced Carbon Fiber Reinforced Composite Materials, Volume II

Topic Information

Dear Colleagues,

This Topic, entitled “Advanced Carbon Fiber Reinforced Composite Materials, Volume II”, focuses on advanced composite materials such as carbon fiber-reinforced plastics (CFRP), which have gained the attention of different industries, such as aerospace, automotive and motorsports industries, which produce lightweight and high-performance components. Advanced composite materials, primarily governed by the properties of reinforcing fibers such as high strength and high stiffness characteristics, are characterized by their high potential in terms of stiffness/weight ratio, making them very attractive for structural applications in which low weight and high stiffness conditions have to be met. The present Topic aims to collect contributions on the advanced carbon-fiber-reinforced composite materials, as well as to review the state-of-the-art on these materials. The manuscripts of this Issue will focus on the most significant and promising manufacturing technologies, machining and joining processes, modeling, simulation, material characterization and failure mechanisms. A comprehensive overview of the most recent results and findings in the field of advanced composite materials will be provided.

With the development of microelectronics products with high density and high power, it is urgent to improve the electrical and thermal conductivity of electronic paste to achieve the new requirements of packaging materials. In this work, a new synthesis method of Ag-MWCNTs was designed: Firstly, carboxylated MWCNTs and stannous chloride were used as raw materials to prepare high-loading-rate Sn-MWCNT composite material to ensure the high loading rate of metal on the MWCNT surface. Then, Ag-MWCNT composite material was prepared by the chemical displacement method to solve the problem of the low loading rate of silver nanoparticles on the MWCNT surface. On the basis of this innovation, we analyzed and compared the electrical, thermal, and mechanical properties of Ag-MWCNT composite electronic paste. Compared with the electronic paste without adding Ag-MWCNTs, the resistivity was reduced by 77%, the thermal conductivity was increased by 66%, and the shear strength was increased by 15%. Therefore, the addition of Ag-MWCNTs effectively improves the electrical, thermal, and mechanical properties of the paste, making it a promising and competitive choice for new packaging materials in the future.

The use of titanium as a biomaterial for the treatment of dental implants has been successful and has become the most viable and common option. However, in the last three decades, new alternatives have emerged, such as polymers that could replace metallic materials. The aim of this research work is to demonstrate the structural effects caused by the fatigue phenomenon and the comparison with polymeric materials that may be biomechanically viable by reducing the stress shielding effect at the bone–implant interface. A numerical simulation was performed using the finite element method. Variables such as Young’s modulus, Poisson’s coefficient, density, yield strength, ultimate strength, and the S-N curve were included. Prior to the simulation, a representative digital model of both a dental implant and the bone was developed. A maximum load of 550 N was applied, and the analysis was considered linear, homogeneous, and isotropic. The results obtained allowed us to observe the mechanical behavior of the dental implant by means of displacements and von Mises forces. They also show the critical areas where the implant tends to fail due to fatigue. Finally, this type of non-destructive analysis proves to be versatile, avoids experimentation on people and/or animals, and reduces costs, and the iteration is unlimited in evaluating various structural parameters (geometry, materials, properties, etc.).
