Summary: The study evaluated the toughening capability of electrospun PA66 nanofibers for carbon/epoxy composite laminates under mode II loading conditions at elevated temperatures. The results showed that the toughness of the nanomodified specimens decreased at higher temperatures due to decreased crack propagation through the nano-layer, a shift from cohesive to adhesive failure as the dominant damage mechanism, and severe plastic deformation of nanofibers at high temperatures.

Summary: Pre-cracked carbon fiber reinforced composite laminates were manufactured and repaired using the vacuum assisted resin transfer molding process. The effects of healing parameters on fracture toughness were investigated using a factorial design of experiments. The results showed that joining temperature had the most significant influence on fracture toughness, followed by contact time. Optimizing the processing parameters can enhance fracture toughness.

Summary: The impact of microdefects on cracking behavior in cross-ply carbon fiber reinforced plastic (CFRP) laminates was investigated. A single artificial defect with a diameter ranging from 2.5 to 50 μm was introduced into the 90 degrees layer. The strain at transverse cracking decreased as the defect diameter increased. There was a minimum defect size required for transverse cracking in cross-ply CFRP laminates. Fiber/matrix debonding occurred around the defect before transverse cracking initiated. The micromechanisms of defect-induced transverse cracking are discussed based on experimental results and fracture-mechanics-based prediction.

Summary: This study presents a method for fabricating carbon nanotube fibre veils on woven carbon fibre/epoxy composite laminates and investigates the effects of interleaf thickness and degree of infiltration on interlaminar properties. The interlaminar fracture toughness under different loading conditions is analyzed, and the failure and toughening mechanisms are systematically studied. The experimental results show that the toughening effects of CNT veils depend on their thickness and degree of resin infiltration, observed by electron microscopy and Raman spectroscopy. The mode I interlaminar fracture toughness increases with increasing CNT veil thickness up to 10 μm, but decreases at 15 μm, while the mode II fracture toughness improves with increasing thickness of CNT veils. The figure of merit for interlaminar reinforcement is significantly high at 58.5, surpassing the current state-of-the-art.

Summary: Interleaving is an effective method to improve delamination resistance in composites. However, there is a lack of design rules for the choice of resin in interleaving. While previous studies suggest that any resin can be used, our research shows that the choice of resin is critical for translating toughness properties.

Summary: This study evaluated the influence of different degrees of crystallinity on PPS/carbon fiber composites processed by hot compression molding, showing that composite samples processed with lower cooling rates exhibit better mechanical properties.

Summary: Automated Fiber Placement (AFP) technology is efficient and accurate, making it suitable for manufacturing composite structures with complex geometry. However, the imperfections caused by this automated method pose challenges to the stability of the composite's mechanical properties. This study experimentally investigates the influence of AFP-induced gaps and overlaps on interlaminar fracture in oven-cured laminates. The findings show that the fracture toughness of the laminates is slightly reduced in the presence of gaps, but significantly increased in the presence of overlaps. Fractographic studies reveal that the increased fracture area and crack length improve the fracture toughness in the overlap group, while the resin-rich area induced by gaps negatively affects delamination resistance.

Summary: Research on the trans-laminar fracture toughness of laminated composites is important, and understanding the fracture process zone at the crack tip is crucial. However, there has been limited research on the early development of the fracture process zone in quasi-isotropic laminates. This study utilized in situ X-ray Computed Tomography (CT) analysis to continuously examine and better understand the entire fracture process zone development during loading. Ex situ CT scanning of a wet conditioned specimen was also used for comparison to explain the significance of 0 degrees splitting in trans-laminar fracture.

Summary: This paper investigates the low-velocity impact response of bolted fiber-reinforced polymer joints in two scenarios, and evaluates the impact of halloysite nanotubes (HNTs) reinforcement of the epoxy matrix. The effects of seawater aging on the impact performance of the joints are also studied, with results showing a decrease in impact resistance after aging, but an improvement when using HNTs reinforced joints. The ToB impact scenario is considered more detrimental than the SoW tests, and a novel damage mechanism is introduced to address the impact of seawater aging.

Summary: In this study, the effects of AFP process parameters and process-induced defects on the mechanical performance of CF/PEKK composites under a hot-wet aging environment were investigated. It was found that the aging process resulted in a mass gain of 0.2 wt% and an increase in the degree of crystallization by almost 14%, while the thermo-mechanical performance decreased by approximately 25%. The impact of gap and overlap defects on the service life of AFP composites can be minimized by using higher compaction forces (600 N) and lower lay-up speeds (0.1 m/s).

The treatment successfully created a porous surface with better hardness, roughness, and wetting, and introduced resin pre-coating (RPC) and carbon nanotube (CNT) fiber bridging to improve the bonding interface. The combined treatments significantly increased the bond strength by up to 156.1%, indicating the feasibility of MAO as an alternative method for manufacturing high-performance Al-CFRP composites in industrial production.
