Summary: The study proposed a multiscale cellulose fiber interlayer made of chopped flax fibers (FFs) and cellulose nanofiber (CNFs) to enhance the interlaminar fracture toughness of carbon fiber/epoxy composites. The addition of this cellulose fiber interlayer resulted in a significant increase in Mode II interlaminar fracture toughness, attributed to a synergistic effect of the FFs and CNFs. The 3D network of chopped FFs alleviated CNFs agglomeration, leading to improved fiber bridging and pull-out during delamination, ultimately hindering interlaminar crack growth.

Summary: This study evaluates the mode-I interlaminar fracture property of 3D-printed continuous fiber reinforced composites with different interlaminar interfaces. Results show that the interlaminar failure of carbon fiber is seriously affected by void defects caused by 3D printing. Furthermore, it is found that the interlaminar fracture toughness can be greatly improved by using Kevlar fiber due to better interlayer bonding and denser bridging fiber. A novel idea for the hybrid interface is proposed based on the characterization study of carbon-Kevlar composites.

Summary: An experimental and computational study was conducted to investigate the toughening effect of nitrogen-doped reduced graphene-oxide particles (ND-RGOP) in delamination of carbon fiber/epoxy laminates. The results showed that the addition of ND-RGOP significantly enhanced the delamination toughness in both mode I and mode II. FESEM images confirmed the rough delamination path and increased interlaminar fracture toughness due to the presence of ND-RGOP. The simulations also supported the toughening effect of ND-RGOP.

Summary: In this study, graphene platelets (GnPs) were used to enhance the inter-laminar interface in carbon fiber (CF) metal laminates (FMLs) for improved mechanical properties. The addition of 0.5 wt% GnPs increased the flexural strength and interlaminar shear strength of FMLs by 39.7% and 53.2%, respectively. Molecular dynamics (MD) simulations confirmed that the low content of GnPs improved the elastic modulus of the matrix and increased resin adsorption on the surface of carbon fiber and Al sheets. Both experimental and MD simulation results demonstrated the effectiveness of adding GnPs in improving the interlaminar mechanical properties of FMLs. This research method can be applied to studying FMLs with other nanomaterials.

Summary: Graphene was successfully employed to improve the mechanical properties of Nb/Nb5Si3 composite, resulting in a graphene reinforced Nb/Nb5Si3 composite with outstanding fracture toughness and compressive strength. The high strength of the composite is attributed to load transfer of graphene and the anchoring effect of the interfacial nanoscale Nb4C3 phase, while the high toughness is attributed to graphene pullout, crack deflection, and crack bridging. The laminated architecture also enhances fracture toughness by promoting minor crack deflection.

Summary: This study investigates the experimental behavior of cementitious ferrocement composite structure reinforced with two types of fabrics (jute and polypropylene). The results show that the type and number of fiber layers have a significant effect on the resistance, strength, and ductility of the cementitious material. Jute fiber-reinforced plates exhibited improved flexural strength and energy absorption with an increased number of layers, while polypropylene fiber-reinforced plates showed the opposite behavior. Furthermore, the bonding between polypropylene fabric laminates was weaker, resulting in horizontal cracks. Overall, this eco-friendly and ductile composite material has promising applications in the construction industry.

Summary: This study presents the synthesis of tin selenide nanoparticles grown on highly conductive, porous 3D graphene foam as a stable host for sodium metal anodes and reveals their energy storage mechanism through conversion reactions. The SnSe@GF electrode exhibits remarkable reversibility after 1500 cycles in asymmetric cells and extraordinary cyclic stability and low overpotentials for 2000 h in symmetric cells. The outstanding performance is attributed to the conversion of crystalline SnSe into low-crystallinity Na15Sn4 and Na2Se dual nucleation sites after pre-sodiation, which enables the formation of a unique interface with high sodium affinity and abundant active sites, resulting in uniform sodium nucleation/plating and dendrite suppression.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
