Summary: This study combined tubular healing fibers with steel fibers to enhance the self-healing capability of cementitious composite materials by aligning healing fibers in the intended stress direction and investigating the impact of a magnetic field on fiber alignment. The efficiency of self-healing was evaluated through permeability and splitting tensile tests, showing that aligned healing fibers outperformed randomly distributed fibers. The observed decrease in mechanical properties due to fiber alignment was considered negligible.

Summary: The addition of HGM significantly reduces the density of the composites. Different degrees of chemical reaction between the Mg alloy melt and HGM wall occur during the fabrication of the composites, resulting in the formation of MgO and Mg2Si. The interface between HGM and matrix alloy can serve as the initiation site for pitting corrosion and increase the exposed area of the matrix in the aggressive medium.

Summary: The remarkable resurgence of fiber metal laminates (FMLs) is mainly due to their hybrid properties of light metals and fibers reinforced polymer (FRP). This study investigated the effect of graphene nanoplatelets (GNPs) on the flexural and Charpy impact properties of FMLs made of aluminum (Al) 2024 reinforced with hybrid glass/Kevlar fibers-epoxy. The results showed that the addition of an appropriate amount of GNPs improved the flexural strength, modulus, and impact strength of FMLs, while higher amounts of GNPs led to a decrease in these properties. Scanning electron microscopy (SEM) observations revealed improved adhesion at the interfaces, but excessive GNPs weakened the FMLs and made them more brittle.

Summary: The flexural and impact properties of hybrid composites consisting of thin-ply unidirectional carbon fibers and basalt fabrics were studied. Embedding the thin-ply UD carbon fibers in the laminates significantly improved the flexural and impact properties. The highest flexural strength and modulus were achieved when the thin-ply UD carbon fibers were placed at the outermost layers. Placing the fibers at the center changed the failure behavior and resulted in a pseudo-ductile behavior.
