Summary: An in situ-curing 3D printing technology was developed, which involved resin impregnation, 3D printing/pre-curing, and post-curing processes. Continuous carbon fiber-reinforced thermosetting phenolic resin (CF/PF) composites were successfully fabricated. The selection of the pre-curing temperature was crucial for the printing process. The deviation distances of the prepregs, degrees of curing, and defect volumes of the composites were used to determine the appropriate pre-curing temperature. With a pre-curing temperature of 260 degrees C, the printed CF/PF composites showed optimal mechanical properties with minimal defects.

Summary: The depletion of natural resources and environmental concerns have led to the development of bio-based non-isocyanate polyurethane (NIPU) resins as sustainable substitutes for harmful isocyanates in the manufacturing of polyurethanes. This review provides a comprehensive analysis of the progress made in utilizing lignin and tannin to produce high-performance NIPU resins for wood adhesive applications. Studies have shown that NIPUs derived from lignin and tannin exhibit enhanced mechanical properties, decreased curing temperatures, and are devoid of isocyanates, making them promising alternatives for wood adhesives.

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: This study evaluates the effects of polyamide (PA) and nano-Al2O3 on the mechanical properties of epoxy resin (EP) and determines the optimal addition content of PA and nano-Al2O3. Epoxy matrix composite (EMC) is prepared using PA as the curing and toughening agent, and nano-Al2O3 modified with a silane coupling agent as the filler. The results show that increasing the PA content improves the impact toughness and plasticity of EMC but reduces its hardness, tensile strength, and wear resistance. Loading nano-Al2O3 fillers in a specific range enhances the mechanical performances of EMC. The research provides a valid technical reference for the industrial application of EMC materials.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.

Summary: The vulnerability of natural fibers to heat and fire poses a significant challenge for their substitution of traditional fiber reinforcements in composite materials. Natural fiber/polymer composites (NFCs) are regarded as potential candidates for engineering applications due to their environmental friendliness and low-impact sourcing. Thus, appropriate approaches need to be implemented to enhance the fire safety of NFCs. This review summarizes and discusses the latest understanding of flammability and thermal properties of natural fibers, with a special focus on their interaction with polymer matrix in fire behavior. Additionally, the latest developments in flame-retardant approaches for NFCs are reviewed, covering both flame retardancy and fire structural integrity. Finally, future prospects and perspectives on fire safety of NFCs are proposed, providing insights into further advancements of NFCs.

Summary: Real-time monitoring of carbon fibre composites during Automated Fibre Placement (AFP) manufacturing remains a challenge for non-destructive evaluation (NDE) techniques. This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
