Summary: A new finite element model (FEM) based on the classical random sequential adsorption algorithm with genetic algorithm (GA) was developed for efficient geometrical construction of short carbon fiber and short glass fiber reinforced polyetherimide (SCF/PEI and SGF/PEI) composites. Experimental tests and model predictions showed good agreement in terms of tensile properties, damage evolutions, and failure modes. The study quantitatively explored the effects of fiber volume fractions, orientations, and lengths on the strength and modulus of SCF/PEI and SGF/PEI composites.

Summary: Short glass fiber reinforced composites (SGFRC) are commonly used for manufacturing parts with complex surfaces. However, the length of fibers often decreases during the manufacturing processes. In this study, 3D CT images were used to analyze the microstructure of SGFRC and the modified Kelly model was employed to calculate the critical length. Micro-failure modes were characterized using micro-CT and scanning electron microscope, and the complex failure mechanisms were analyzed. The micro failure modes were mainly influenced by the micro geometric features and mass fraction of short fibers.

Summary: The effects of thermal aging at temperatures between 85℃ and 145℃ on the tensile and flexural mechanical properties of 20% glass fiber-reinforced PBT composites were investigated. The results indicate that as the aging temperature increases, the tensile and flexural strength of the composites significantly decrease, while the elastic modulus remains almost unchanged. The decrease in strength and occurrence of brittle fracture can be attributed to the weakening of the interfacial adhesion between the GF and PBT matrix caused by the difference in thermal expansion coefficients.

Summary: Continuous alumina fiber-reinforced alumina matrix composites were prepared and characterized. The damage mechanism of the composites was investigated using acoustic emission technology, revealing that cracks started and expanded in the matrix when the load increased. Delamination failure occurred during the short-beam shear test due to crack instability along the interlayer. Many fibers in the composites were crushed synchronously with the matrix as specimen deformation increased.

Summary: This paper presents an experimental approach of three-dimensional woven carbon/carbon composites arranged in various geometrical configurations. Seven types of samples were tested under pin-loading to determine the effects of width-to-hole diameter ratio (W/D), edge distance -to-hole diameter ratio (E/D) and hole diameter -to-thickness ratio (D/t) on the failure mode. The experimental results and observations indicated that net-tension failure and shearing-out failure switched to bearing failure with the increasing ratio of W/D and E/D, respectively.

Summary: This study presents a peridynamic (PD) approach to model progressive failure in fiber steered composites. The PD bonds enable the interaction of material points within each ply as well as their interaction with other material points in the adjacent plies. The capability of this approach is demonstrated by capturing the correct deformation field as well as the damage initiation site and its progressive growth.

Summary: The natural extract silymarin was found to be more efficient than its main component silybin in stabilizing polyethylene, especially at higher concentrations. Silymarin preserved the vinyl group content and MFR of the polymer better, and showed slightly better residual stability compared to silybin at the same additive content. The smaller bond dissociation enthalpies and higher solubility of silymarin contributed to its greater efficiency.

Summary: This paper investigates the effect of impact damage on the fatigue behavior of CF/PEEK-titanium hybrid laminates. A fatigue life model is proposed to predict the S-N curves of the laminates based on energy dissipation approach. The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined. The validity of the proposed model is verified through fatigue tests under different stress ratios and impact energy levels.
