Summary: Geopolymer wood composites (GWC) serve as a green alternative to Portland cement wood composites in construction, and the wood's initial moisture content affects the material properties of GWC. The study found that using wood with higher moisture content resulted in more structurally bound water in the GWC, while using dry wood led to higher density, compressive strength, and lower porosity in the composites.

Summary: This study investigated the influence of porosity on the mechanical properties of a NextelTM 610/Al2O3-ZrO2 composite. The results showed that as the porosity decreased, the bending strength and strain of the material also decreased. Additionally, the material lost its damage-tolerant behavior at a submicron porosity of 37%.

Summary: This study investigates the interlaminar properties of a C/SiC composite produced by Liquid Silicon Infiltration through experiments and numerical analysis. Experimental methods are introduced to obtain pre-cracks with sharp tips at precise locations, and specimens with different thicknesses are used to study the effects of bending stress states in the delamination process. Numerical techniques are utilized to identify the properties of tri-linear Cohesive Zone Models for simulating delamination, without additional assumptions or testing. The study also considers fiber bridging effects and evaluates process zone lengths using different experimental, analytical, and numerical methods. Overall, the study provides qualitative insights into the delamination process of cost-affordable long fiber reinforced C/SiC laminates, and proposes an experimental and numerical protocol that takes into account the scattering of material properties.

Summary: Unidirectional SiCf/SiC-matrix composites with a pyrocarbon interface were prepared by hot-pressing SiC nano powder at high temperature (1900 degrees C) and pressure (20 MPa). The volume fraction of SiC reinforcing fiber significantly affected densification and mechanical properties, with improvements in mechanical properties observed with an increase in fiber volume fraction up to a certain level, beyond which the ultimate strength degraded due to open porosity and fiber damage.

Summary: This paper develops a micromechanical tension-compression fatigue hysteresis loops model for fiber-reinforced ceramic matrix composites, characterizing the stress-strain behavior using multiple micromechanical damage parameters. The analysis of tension-compression fatigue hysteresis loops for unidirectional SiC/CAS composites under different conditions reveals the effects of material properties, damage stage, and fatigue stresses on the behavior of the material. Additionally, experimental predictions of stress-strain hysteresis loops using the developed models show distinct responses under different compressive stress levels.

Summary: This study investigates the effects of rare earth oxides on carbon fibre-ZrB2/SiC composites and finds that the addition of Y2O3, La2O3, and CeO2 improves the densification of the material, while Sc2O3 promotes the formation of solid solutions in the matrix. All the composites exhibit improved mechanical properties, but CeO2 is detrimental to the long-term structural stability.

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.
