Summary: This paper investigates the interlaminar bond strength of laser in-situ consolidation CF/PEEK thermoplastic composites. The results show that porosity significantly affects the interlaminar shear strength, while there is no correlation between crystallinity and interlaminar shear strength. The interlaminar shear strength in the heated tool in-situ consolidation group is significantly higher than the constant pressure in-situ consolidation group.

Summary: The introduction of hyperbranched structure and fluorine groups in epoxy-preFHBPBO significantly improved the mechanical properties and wave-transparent performance of PBO fibers reinforced BADCy resins composites. The addition of 7 wt% epoxy-preFHBPBO increased the flexural strength and interlaminar shear strength, while reducing dielectric constant and dielectric loss compared to PBO fibers/BADCy composites. Moreover, the volume resistivity and breakdown strength were also enhanced in PBO fibers/FHBPBO-co-BADCy composites.

Summary: Studies have shown that the fraction of the secondary filler inducing the maximum synergistic effect decreases with increasing total filler content, leading to an anti-synergistic effect at high fractions. Effective phonon transfer and high thermal conductivity can be achieved at the optimum fraction due to improved filler network formation. The Kim-Jang-Lee model was proposed for both the synergistic and anti-synergistic effects based on the ratio of fillers in the composites.

Summary: This study proposes an interesting strategy to simultaneously increase the tensile strength and fracture toughness of epoxy matrix by in-situ constructing block copolymer nanostructures. Through the optimization of nanostructures, the tensile strength and fracture toughness of epoxy matrix are increased by 19% and 236%, respectively, without lowering its Tg. The impact of block copolymers on the morphologies and transformation of nanostructures, the relationship between nanostructures and epoxy properties, and the strengthening and toughening mechanism are systematically studied. Moreover, the epoxy resins with excellent tensile properties and toughness are used to enhance the compressive and interfacial properties of CFRP composites.

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.
