Summary: A novel co-curing process using carbon fibre/PEEK tapes was proposed for bonding carbon fibre/epoxy composites, resulting in significantly improved structure integrity and thermal stability. The co-cured joints exhibited increased lap-shear strengths, extended fatigue life, and enhanced mode-I and mode-II fracture energies compared to joints bonded with traditional aerospace structural adhesives. The failure analysis revealed that plastic deformation, resin breakage, and carbon fibre delamination were the main failure mechanisms of the CF/PEEK bonded joints.

Summary: This study investigates the effect of CFRP layup on the crack initiation and propagation of composite bonded joints under mode I loading to enhance their damage tolerance. Quasi-static tests and finite element analyses were conducted on four CFRP layups bonded with two adhesives to understand the various damage mechanisms. The results reveal that CFRP layup and adhesive fracture toughness significantly affect the joint fracture phenomena. Tailoring the CFRP layup shows promise in increasing the maximum effective fracture toughness by up to 100% compared to cohesive failure.

Summary: The study aims to characterize the performance of four different composite/composite single lap joint configurations at various loading rates through experimental methods. The lap joints are tested using tensile split-Hopkinson bar and fatigue testing machine. Experimental results show that the peak load, initial stiffness, and energy absorbed generally increase with loading rates, while the plateau load is relatively insensitive to loading rates. Finite element analysis using Abaqus/Explicit solver qualitatively explains the experimental observations by considering the rate dependency of adhesive.

Summary: This paper investigates the effects of cooling rates on the crystallization behavior, interfacial bonding strength, interlaminar fracture toughness and low-velocity impact performance of carbon fiber reinforced poly(aryl ether ketone) (PAEK) and poly(ether ether ketone) (PEEK) composites. The results show that PAEK has lower crystallinity and smaller crystals compared to PEEK at the same cooling rate. The lower crystallinity and smaller crystals of PAEK contribute to improved matrix ductility and interfacial bonding strength in the composites. Under water cooling conditions, the impact damage area of CF/PAEK is about 71% lower than that of CF/PEEK, while the CAI is about 14% higher.

Summary: This study investigates the impact of graphene nanoplatelets (GNPs) and hexagonal boron nitride (hBN) on the thermal and mechanical properties of polydimethylsiloxane (PDMS) matrix for thermal interface materials (TIMs). The inclusion of 10 wt% GNPs and 40 wt% hBN in PDMS resulted in a TIM with a through-plane thermal conductivity (TC) of 1.24 W m(-1) K-1, showing a significant increase of 519% compared to the neat matrix. A synergistic effect between GNPs and hBN was observed when 8 wt% of hBN was replaced by GNPs, leading to a 33% increase in TC in samples with 48 wt% total filler content. The addition of GNPs also enhanced the elongation at break and reduced the shore hardness of the samples.

Summary: Tungsten network reinforced functionally graded copper composites were prepared using an integrated 3D printing and infiltration technology to improve high temperature ablation properties of nuclear fusion divertor materials. The composites' ablation behavior was systematically investigated using an argon arc welding torch. Results showed that mass loss of composites was increased firstly but then decreased with the increase of ablation time. During ablation, evaporation of the melted copper reduces the local temperature of tungsten skeleton, whose high melting point also restrict the further evaporation of copper. These mechanisms significantly improve the ablative resistance of CuW gradient composite. Tungsten twinning structures were identified to form during ultra-high temperature (at 6273.15 K) ablation process in a cold environment in air. The formation of distinctive W twinning structures and gradient distribution of copper and tungsten skeleton were identified as the key mechanisms for the significantly enhanced ablation performance of the graded composite.

Summary: Metal-organic framework (MOF)-derived trimetallic FeCoNi oxides (FCN-MOS) with a mesoporous structure were synthesized through one-step hydrothermal reaction and calcination. The FCN-MOS system consists of three main phases, alpha-Fe2O3 (n-type), CoFe2O4, and NiFe2O4 (p-type), and the nanostructure and pore size can be controlled by altering the content of alpha-Fe2O3, CoFe2O4, and NiFe2O4. The sensors based on FCN-MOS exhibit a high response of 71.9, good selectivity towards 100 ppm ethanol at 250 degrees C, and long-term stability up to 60 days. Additionally, the FCN-MOS-based sensors show a p-n transition gas sensing behavior with the alteration of the Fe/Co/Ni ratio.

Summary: Photocatalytic technology utilizing sunlight as a driving force can convert solar energy into other energy sources for storage and use. CdS, as a typical reducing semiconductor, has attracted attention in photocatalysis due to its suitable bandgap and strong reducing ability. However, the photocatalytic performance of CdS is limited by carrier recombination and photocorrosion. Therefore, CdS has been widely developed as a reducing photocatalyst in constructing S-scheme heterojunctions to overcome these limitations.

Summary: A novel compliant spinal fixation based on compliant mechanisms is designed to effectively reduce stress-shielding effect and adjacent segment degeneration (ASD), but it requires high properties of the used materials. Bulk metallic glasses (BMGs), as young biomaterials, demonstrate excellent comprehensive properties, making them attractive for compliant spinal fixation. In this study, the large deflection deformation behaviors of Zr61Ti2Cu25Al12 (at.%, ZT1) BMG beam were systematically investigated, including elastic, yielding, and plastic deformations. The theoretical nonlinear analytical solution curve predicts the load-deflection relation within the elastic deformation regime and assists in capturing the yielding event, serving as a powerful design tool for engineers. To accurately capture the beginning of the yielding event in biomedical implant applications, the concept of bending proof strength (sigma p,0.05%) with tiny permanent strain of 0.05% was proposed and determined, which is significant for setting the allowable operating limits of the basic flexible elements. The plastic deformation driven by the bending moment can be classified into two stages: the initial stage characterized by nucleation and intense interaction of shear bands, and the second stage dominated by the progressive propagation of shear bands and emergence of shear offsets. The plasticity of BMG beam structures depends on the BMG's inherent plastic zone size (rp), and when the half beam thickness is less than that of rp, the plastic deformation of BMGs behaves in a stable manner, effectively serving as the margin of safety.

Summary: Fe-based metallic glasses are promising materials in the fields of advanced magnetism and sensors. This study proposes a novel approach to tailor the amorphous structure through liquid-liquid phase transition, and provides insights into the correlation between structural disorder and magnetic order. The results show that the liquid-liquid phase transition can induce more locally ordered nanodomains, leading to stronger exchange interactions and increased saturation magnetization. The increased local heterogeneity also enhances magnetic anisotropy, resulting in a better stress-impedance effect.

Summary: Metal-organic frameworks derived composites are promising EMW absorbers. Cation substitution can improve their absorption performance by regulating morphology and atomic space occupation. However, the mechanisms of how cation substitution affects EMW absorption performance are still not well understood. In this study, imidazolic MOFs were fabricated and tailored by cation substitution strategy to prepare porous composites. The samples showed optimal reflection loss and effective absorption bandwidth values under low filling rate and thin thickness conditions. The intercoupling between multiple atoms and the porous structure introduced by cation substitution contribute to the improved absorption performance.
