Summary: Through MD simulations, it was found that the binding energy between the CL-20/TNT co-crystal surface and F-2311 increased with higher F-2311 content, leading to reduced sensitivity and improved thermal stability. Additionally, hydrogen bonds were observed between F-2311 molecules and CL-20/TNT molecules. The mechanical data also showed that increasing F-2311 content decreased the rigidity and increased the toughness of the CL-20/TNT based PBXs.

Summary: This study proposes a machine-learning approach to achieve virtual screening (VS) for solid hydrogen-bonded oligomers with high accuracy (>93%). A synthetic library consisting of 770 structurally diverse oligo-dimethylsiloxane (oDMS) with different hydrogen-bonding motifs was constructed, and the solid/fluid-state labels of oDMS were obtained through rheological measurements. Tailored descriptors for hydrogen-bonding motifs, derived from quantum chemistry calculation and analysis, were used for machine learning algorithms, including interaction energy, AlogP98, molecular flexibility, van der Waals area, and Connolly surface occupied volume values. The eXtreme Gradient Boosting (XGBoost) model showed the best prediction accuracy among the investigated algorithms, and the interpretation of the XGBoost model provides feasible VS routines for the discovery of solid hydrogen-bonded oligomers.

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.
