Summary: A TiB2/Al-Cu-Mg-Ni composite with a small amount of Sc was successfully fabricated using laser powder bed fusion. The composite exhibited a yield strength of -370 MPa and an elongation of -7%, nearly doubling the strength of the wrought matrix counterpart. These excellent mechanical properties can be attributed to the unique micro-nano hierarchical microstructure, which consists of dispersed TiB2 particles, fine aluminum grains, intermetallic nanoparticles, and nanocellular networks. The additive manufacturing process played a crucial role in tailoring the microstructure of the particulate reinforced metal matrix composites and enhancing their properties.

Summary: Multi-material structure fabrication has the potential to address critical challenges in today's industrial paradigm. Laser-directed energy deposition (L-DED) is preferred for multi-material additive manufacturing, especially in alloy design, metal matrix composites (MMC), and functionally graded materials (FGM). However, there are still challenges in tightly controlling the composition of the powder mixture, understanding the thermal history's influence, and studying the durability and failure modes of MMCs and FGMs.

Summary: Dual-curing thermosetting systems have been developed as an alternative to conventional curing systems, offering processing flexibility and the ability to enhance properties of cured parts. These systems, particularly in 3D printing technologies, aim to improve quality and properties of printed parts, with the added benefit of controlling the curing sequence for tailored structure and properties. This opens up opportunities for novel applications based on the controlled reactivity and functionality of the intermediate material and final consolidation of 3D-printed parts.

Summary: This paper investigates the tool-ply friction behavior of jute/PLA biocomposites in thermoforming. A pull-through friction testing device was developed to characterize the tool-ply friction behavior of jute/PLA prepreg at elevated temperature. The effects of alkali treatment, fiber orientation, normal force, and slipping velocity were studied, and a quantitative definition of tool-ply friction behavior was achieved. The results indicate a strong relationship between tool-ply friction behavior and woven and fiber structures, indicating hydrodynamic lubrication.

Summary: Micro-arc oxidation (MAO) treatment was used to modify aluminum (Al) alloys in order to improve bond strength with carbon fiber reinforced polymer (CFRP). The treatment successfully created a porous surface with better hardness, roughness, and wetting, and introduced resin pre-coating (RPC) and carbon nanotube (CNT) fiber bridging to improve the bonding interface. The combined treatments significantly increased the bond strength by up to 156.1%, indicating the feasibility of MAO as an alternative method for manufacturing high-performance Al-CFRP composites in industrial production.

Summary: Faster heating rates and higher process temperatures can reduce the total process time while achieving the same degree-of-cure. Thermal analysis shows that thermoplastic interleaf particles melt at the recommended curing temperature. A short dwell at a lower temperature can prevent the mixing of thermoplastic particles and thermoset pre-polymer.

Summary: In response to the global environmental pollution crisis caused by waste plastics, recyclable design is an effective solution. A CPVC/PUA nanocomposite foam was developed using the plasticizing-foaming-reinforcing strategy, combined with catalytic carbonization. The foam exhibited high expansion ratio, robustness, solvent resistance, flame-triggered shape memory effect, and ablation resistance. The foam could be directly upcycled into functional carbon foam with attractive electromagnetic interference shielding performance.
