Summary: Alternate coatings of HfC-TaC/HfC-SiC with different sublayer thicknesses were fabricated on SiC-coated carbon/carbon composites, showing the best ablation performance due to the dense oxide layer and stress release from dendritic cracks. Additionally, exfoliation at the interface of adjacent sublayers in some coatings led to violent evaporation of exposed sublayers.

Summary: Mullite-modified C/C-HfC-SiC composites were prepared by precursor infiltration and pyrolysis, and their phase composition, microstructure, and cyclic ablation behavior were investigated. Compared to C/C-HfC-SiC composites, the mullite-modified composites exhibited better ablation resistance. The structures transformed from HfO2-SiO2 to HfSiO4-wrapped carbon fibers and island shape HfO2-HfSiO4-SiO2 layer after successive ablations. The modified composites showed improved mass ablation rates after the formation of HfSiO4.

Summary: In this study, repeated impact tests were conducted to investigate the multiple impact response of stainless steel-lightweight high ductility cement composite (LHDCC) beams. Detailed analysis was carried out on the failure modes, impact force history, displacement history, velocity history, strain history, and reaction force-displacement curve of the composite beams under multiple impacts. Finite element simulation using LS-DYNA was used to study the impact and energy dissipation of the composite beams, and the multi-drop hammer modeling method was proposed for simulating multiple impact scenarios. Uniaxial and triaxial tests on LHDCC materials were conducted to calibrate the parameters of the Continuous Surface Cap Model (CSCM) constitutive model, and the numerical results were in good agreement with the experimental results.

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: 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.
