Summary: The present study aimed to enhance the biocompatibility and antimicrobial properties of Ti6Al4V (Ti64) alloy powder by incorporating Ca2' and Ag' ions through chemical treatment and ion exchange. The modified Ti64 alloy powder exhibited a fine porous network structure and the evolution of different titania phases upon heat treatment. The HR-TEM and EDX results confirmed the incorporation of Ca2' ions and the transformation of Ag' ions into AgNPs, which were decorated on the nano porous network structure. The optimized concentration of AgNPs decorated Ti64 alloy powder showed antimicrobial activity against both Gram-positive S. aureus and Gram-negative E. coli bacteria, and was compatible with MG63 cell lines. The surface modified Ti64 alloy powder was used as reinforcement for gelatin-chitosan composite scaffold fabrication, and the resulting scaffold exhibited suitable pore morphology and distribution, along with low in-vitro cell toxicity towards MG-63 cell lines.

Summary: This research investigates the impacts of surface treatment and the number of ramie fiber layers on the vibrational and mechanical characteristics of a glass/ramie fiber reinforced hybrid polymer composite. The study found that hybridization and NaOH pre-treatment to a certain ratio can increase the mechanical strength of the hybrid composite compared to natural fiber composites.

Summary: This paper presents the uniaxial tensile experiment results and analysis of a new steel fiber-reinforced-carbon/glass hybrid composite bars (S-CG HCBs). The effects of carbon/glass ratio, steel fiber replacement ratio, fiber volume fraction, and fiber arrangement on the tensile properties of S-CG HCBs were investigated. The results showed that adding steel fiber modified the tensile stress-strain relationship and effectively controlled the mechanical properties of S-CG HCBs, including yield stress, rupture stress, failure stress, and stress drop at carbon fiber fracture. A tensile stress-strain model considering the fiber distribution pattern was proposed.

Summary: In this study, a biodegradable Zn-1Mg-1Cu-1HA (ZHA) and Zn-1Mg-1Cu-1ZrO2 (ZZR) composite was created using the stir-casting process and enhanced with a ceramic composite coating by electrodeposition technique. Microstructural analysis revealed uniform distribution of fine MgZn2 and CuZn2 phases in an α-Zn matrix. The mechanical test confirmed high tensile and compressive properties of the ZZR composite, along with low corrosion rate and degradation rate, and good cell viability. Overall, the coated ZZR composite shows promise as a material for implant applications.

Summary: Microcellular injection molding (MIM) is a flexible, efficient, and environmentally friendly foaming technology used to prepare plastic foams with complex shapes. Mold-opening microcellular injection molding (MOMIM) was used to prepare high-performance polypropylene/glass fiber (PP/GF) composite foams, which exhibit significantly improved mechanical properties compared to pure PP foams. MOMIM can enhance the flexural modulus of molded samples, and the addition of glass fiber in PP/GF composites can greatly increase tensile strength and modulus.

Summary: This study developed composited structural insulated panels (CSIPs) with GFRP and GFRC materials to improve thermal properties and energy savings in buildings. Simulation results using ANSYS and EnergyPlus showed that GFRP SIPs outperformed steel SIPs in terms of energy consumption and thermal performance. Reducing stud web area and using less conductive materials can effectively enhance the thermal properties of SIPs.

Summary: The production of lightweight vehicles is driven by the global challenges of fuel economy enhancement and greenhouse gas emissions reduction. Lightweight materials, such as fiber-reinforced plastics (FRP) composites, are being developed to replace conventional materials like steel and cast iron to achieve fuel efficiency and CO2 emission reduction. However, the damage of FRP composites under impact loading is a critical factor that affects their structural application. This paper focuses on the use of high-strength glass fibers as the reinforcing member to develop a car bumper beam, discussing its mechanical performance and manufacturing techniques. Based on literature studies, glass fiber-reinforced composite (GRP) shows more promise in the automotive industry compared to conventional car bumper beams.

Summary: This study examines the feasibility of recycling glass fiber reinforced polymer (GFRP) and carbon fiber reinforced polymer (CFRP) waste in pervious concrete (PC) and quantifies their environmental impacts through a lifecycle assessment (LCA) framework. Results show that the inclusion of GFRP and CFRP can improve the flexural strength of PC, and the environmental impacts of recycling CW in PC pavement systems are relatively small compared to the production of raw materials.
