Summary: This study investigated the properties of WF fibres reinforced HDPE biocomposites produced by injection moulding. The results showed that adding WF fibres improved mechanical properties but slightly reduced impact resistance. The thermal analysis revealed that the addition of WF fibres decreased the melting temperature, leading to accelerated degradation of the biocomposite. The biocomposites with 20% WF fibre mass ratio exhibited good mechanical and thermal properties compared to those with 30% WF.

Summary: The mechanical dependence of 3D-printed thermoplastic polyurethane (TPU) reinforced with continuous carbon fibres (CCFs) on selected printing conditions was investigated. The study evaluated the impact of layer thickness, printing speed, and layer number on the tensile, flexural, and cryo-impact properties of the printed specimens. Results showed significant improvements in tensile yield stress and flexural strength when using CCFs reinforcement, with preimpregnated CCFs (PCCFs) providing the highest enhancement. The structure-property relationship was established through interface microstructure detection and simulation.

Summary: A glass fiber/polypropylene semi-impregnated lamina was added to improve the weldability of an epoxy laminate. Ultrasonic welding of the hybrid composite was performed with varying welding parameters, resulting in different lap-shear strengths and weld interface qualities. The welding time had a significant influence on the intermixing of the thermoplastic layer and the formation of a strong weld area, while the amplitude and pressure mainly affected the power absorption and overall welding performance.

Summary: Currently, the utilization of wood residues for the preparation of bio-composites is crucial due to the shortage of wood resources. By using wood fibers as raw materials, transparent fiber wood (TFW) can be created, which helps in environmental protection and energy saving. This study successfully prepared wood powder-reinforced transparent wood (TCWP) by impregnating delignified wood powder (WPF) with epoxy resin (EP), improving the efficiency by over 50%. The study also investigated the effects of WPF size and fiber mass fraction on the properties of TCWP and found that an 80-mesh WPF with a 5% fiber mass fraction had the best optical, thermal, and mechanical properties. TCWP can be utilized as optical screens and architectural glass in engineering practices, offering a high-value transparent composite material.

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.
