Summary: A cyclic indentation test was conducted on PR520 epoxy resin and its 3D interlock carbon fiber reinforced composite to study the effects of thermo-oxidative aging on local material properties. The analysis showed that elastic and plastic behavior were affected by thermal aging, while viscoelastic behavior remained unchanged. A property gradient was measured through the thickness of aged samples, with the affected zone extending about 150 µm from the surface exposed to the oxidative environment.

Summary: The study found that spreading commingled carbon fiber/nylon fiber yarns can effectively reduce the impregnation distance, with rapid nylon resin impregnation on the carbon fibers. However, an increase in molding time resulted in a slight decrease in tensile strength and tensile fracture strain, as well as degradation of the nylon resin. The effects of molding time on flexural strength, flexural modulus, and flexural fracture strain were negligible.

Summary: A method of microwave heating assisted additive manufacturing is proposed to achieve higher speed and efficiency in manufacturing Continuous Carbon Fiber Reinforced Plastic (CCFRP). By investigating the permittivity of printed specimens with different fiber volume fractions and establishing a micro-scale microwave radiation and heat transfer model, the relationship between temperature difference, filament diameter, and printing speed has been revealed. Thermal and microwave printed specimens were studied for non-isothermal crystallization behavior and mechanical strengths, with analysis conducted to explain the different results.

Summary: The choice of manufacturing process, raw materials, and process parameters has a significant impact on the quality of pre-consolidated tapes used in thermoplastic pultrusion. This study compared commercially available tapes to inhouse-made tapes, and found that the inhouse-made tapes produced pultruded composites with higher mechanical properties. Differences in the manufacturing methods of pre-consolidated tapes resulted in variations in glass fiber impregnation and mechanical properties.

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.
