Summary: The Bouligand structure is a helical structure where the rotation pitch angle is related to the mechanical performance of the layers, with an optimal pitch angle for lowest shear stress. Experimental tests on 32-layer carbon fiber laminates showed that the predicted optimal angle of 9.1 degrees achieved the highest load-bearing capability and delayed delamination, providing a fundamental basis for design.

Summary: Shear failure parallel to grain is a common failure mode for bamboo scrimber under flexural loading. The bamboo scrimber beams were reinforced with bamboo pins to address this issue. Four-point bending tests were carried out to analyze the failure mechanism, ultimate bearing capacity, load-deflection curves, load-strain relationship, strain distribution, and interlayer slip law of the bamboo scrimber beams. It was found that the bamboo pins effectively resisted shear failure and increased the ultimate bearing capacity of the beams.

Summary: This study investigates the influence of contact angle (CA) and contact angle hysteresis (CAH) on humid air condensation and reveals their different roles in different stages of the condensation cycle. The findings show that increasing CAH has a negative effect on condensation heat transfer, while the impact of changing CA varies. Lower CAH values have a greater impact on enhancing condensation heat transfer, and increasing CAH has a more significant effect on hydrophobic surfaces than on hydrophilic surfaces. Additionally, decreasing CAH has a more pronounced effect on improving condensation heat transfer than increasing CA.

Summary: In this study, a predictive approach using microdroplet test and finite element modeling was utilized to investigate the quality of interface for polymer drops bonded single flax fiber. The results showed that the interfacial stiffness and fiber-matrix separation displacement played a crucial role in triggering the debonding behavior. The best performing system was found to be flax fiber/PLA, with a maximum fiber-matrix separation of 156 μm and an interfacial stiffness of 47 GPa/mm, while the worst performing system was flax fiber/PP, with a limited fiber-matrix separation of 55 μm. The proposed numerical model was able to capture the interfacial shear behavior of polymeric drops bonded to a single flax fiber.

Summary: The paper focuses on the behavior of glued joints of wooden sections at elevated temperatures. The study found that the curing of PRF and PUR adhesives was insufficient at high temperatures. At 140℃, there was no significant reduction in strength for all tested adhesives, but a longer duration (1 day) led to a decrease in tensile shear strength. At 170℃, PRF and EPI showed a significant drop in strength, while PUR lost its strength completely after longer duration exposures.
