Summary: This article introduces stiff and tough biocomposites prepared by in-situ polymerisation of poly (methyl methacrylate) and ductile non-dry flax fibres. The results show that composites processed with non-dry fibres have comparable shear strength but higher elongation at failure and toughness compared to composites processed with oven-dried fibres. Additionally, non-dry flax fibres significantly increase the perforation energy of flax-PMMA composites under low-velocity impact. The study also investigates the effect of non-dry fibres on fatigue life and failure mode of the composites.

Summary: In this study, the mechanical behavior and microstructural changes of a novel high elongation Nitrate Ester Plasticized Polyether (NEPE) propellant were investigated using a computational representative volume element (RVE) model. The results showed that the strain rate influenced local damage, and the particle size was not the most critical factor for interface debonding. The damage characteristics under tension included interface debonding, fibrillar matrix, cavities, and catastrophic cracks orthogonal to the loading direction, while the damage characteristics under compression included in-layer tearing fracture inclined at approximately 45 degrees to the loading direction.

Summary: This study proposes a novel approach using finite element modeling to comprehensively simulate the stress redistribution around a broken fiber in unidirectional composites. The parametric study reveals that factors such as friction coefficient and interfacial fracture toughness significantly affect the stress concentration factor of intact fibers. Introducing interfacial debonding reduces the overpredictions of stress concentration factor.

Summary: The use of micro fibres as reinforcement in Ultra-High Performance Concrete (UHPC) enhances its mechanical properties. To achieve an optimal bonding between fibre and cementitious matrix, a coating of fibres with a thermoplastic elastomer is proposed in this study. The pullout tests and flexural strength tests reveal that the coating improves the adhesive bond between fibre and UHPC matrix, but the results differ when inclined fibres are tested.

Summary: The fracture behavior of an in situ TiB2 particle reinforced 7075 aluminum matrix composite in various stress states was investigated. The fracture mechanism was characterized and different damage mechanisms were analyzed. A modified ductile fracture criterion, considering the influence of both the maximum principal stress and maximum shear stress, was developed and shown to predict the fracture behavior more accurately than other models.

Summary: This study implemented and evaluated a continuum damage mechanics-based material model to predict the damage and mechanical response of carbon fibre reinforced polymer composites under low velocity impact. The use of both Cuntze and Puck failure criteria, along with a novel approach to search for the fracture angle, demonstrated efficient and accurate prediction of the matrix damage caused by low velocity impact. The simpler failure model of Cuntze proved to be more preferable for explicit simulations due to reduced computational time.

Summary: The study focused on the fracture debonding law and fracture criterion for rock-concrete binary composite interfaces under freeze-thaw (F-T) actions, using sandstone-concrete binary composite materials as the research object. It was found that the interface influence zone (IIZ) lies in the sandstone near the interface, and the interface crack tends to initiate and propagate mainly along the interface under F-T cycles. The study also discussed the initiation law and influencing factors of interface cracks under F-T actions.

Summary: Longitudinal fibre-matrix debonding is influenced by various factors such as interfacial strength, fracture toughness, thermal residual stresses, friction, and matrix plasticity. The proposed finite element model accounts for these factors and allows for debond propagation based on assigned interfacial properties. Parametric studies demonstrate that higher values for interfacial friction coefficient, thermal residual stress, and interfacial fracture toughness restrict debond propagation, while matrix plasticity facilitates it.

Summary: The sizing treatment significantly increased the interface toughness, while having little effect on the peak stress of the fibre-matrix interface. The characteristics of the fracture surfaces and scission of C-O bonds observed in the simulations are consistent with previous experimental observations. This new modelling method opens up a new avenue for investigating the deterioration mechanism of FRP under combined mechanical-chemical-thermal actions.

Summary: Silk fibers have great potential for high impact resistance in composites due to their stiffness, strength, and high strain to failure. Using thermoplastic matrix materials with high strain to failure can enhance the impact resistance above that of the pure matrices. The adhesion between fiber and matrix and the fiber architecture also play significant roles in impact resistance.

Summary: Fatigue and impact resistance are important in structural biocomposites, and graphene oxide (GO) can enhance their mechanical performance. However, most studies have focused on the microscale and quasi-static behaviors of GO-modified composites. This study shows that GO surface modification of flax fibers decreases the slope of the S-N curve by 17% and promotes fiber pull-outs during failure. GO modification delays impact damage initiation and prolongs the stable damage progression phase, improving damping performance below the perforation limit.

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.
