Summary: Three-dimensional braided sandwich hybrid composites with interlaminar fiber connection were designed and fabricated using the yarn interlacing rule in three-dimensional four-step braiding technology. Short-beam shear tests showed that the 3D braided sandwich hybrid composites effectively resisted delamination and exhibited better deformability and structural toughness.

Summary: The study focused on enhancing the interlaminar properties of composites by depositing carbon nanotubes on carbon fiber surfaces. The results showed improved adhesion between carbon fibers and the matrix, leading to increased shear strength and fracture toughness. However, limitations were observed in the fracture toughness analysis due to fragile pathways in intralaminar regions.

Summary: This paper explores the influence of different transverse layers on the interlaminar shear performance of CLT. The results show that the interlaminar shear strength of CLT is significantly affected by the type of transverse layer used. The failure modes of interlaminar shear also vary depending on the transverse layer material.

Summary: Novel mass-producible MWCNT-anchored carbon fiber was developed and applied as a new incorporation into CFRTPs to improve the material's properties. Based on the results, an optimal concentration and process method for MWCNT anchoring were suggested, and the anchored MWCNTs significantly enhanced the impact resistance and ILSS of the CFRTPs.

Summary: The effects of four types of stitch yarns on the interlaminar shear strength and failure behavior of 3D stitched composites were investigated at room temperature and 100 degrees C. The study found that the mechanical properties of the stitch yarns play a dominant role in determining the interlaminar shear strength at room temperature, with PBO stitch yarns showing the best performance. At 100 degrees C, the stitch yarns/resin interface performance becomes the decisive factor, with CF stitch yarns showing the best interlaminar shear performance. The use of stitching significantly improves the interlaminar shear strength at 100 degrees C, and silk fiber has the advantage of replacing carbon fiber at room temperature while maintaining mechanical properties.

Summary: This study successfully modified epoxy resins with graphene oxide (GO) to manufacture carbon fiber reinforced polymer (CFRP) composites for cryogenic environments. The addition of GO improved the interlaminar shear strength (ILSS) and reduced the coefficient of thermal expansion (CTE) of the composites. Cryo-thermal cycling had an effect on the ILSS and CTE of the CF/GO-modified epoxy composites.

Summary: This study proposes a netting and anchoring strategy for high-performance stretchable electronics. By adding a small amount of polyborosiloxane (PBS) prepolymer, the formed PBS networks can both physically entangle with the PDMS networks and anchor them to adherent surfaces with reversible bonds. The obtained composites exhibit high adhesion strength and conductivity due to good wettability, uniform interfacial bonding, and stress transfer for energy dissipation.

Summary: The study focused on enhancing magnesium alloy composites by grafting different amounts of carbon nanotubes onto carbon fiber surfaces. Moderate interlaminar shear strength was found to be beneficial for improving tensile properties, with the presence of carbon nanotubes delaying crack propagation and increasing energy consumption to enhance strength. Adjusting the quantities of grafted carbon nanotubes optimized crack propagation paths and affected stress distribution, crack initiation, and propagation.

Summary: This study focuses on the improvement of experimental methods for studying interlaminar shear properties and failure behavior of fiber-reinforced composites under biaxial loading. A new experimental approach is developed for reliable determination of interlaminar shear properties using a standard testing machine. The study includes stress analysis, fracture mechanism analysis, and stress-strain curve analysis using finite element modeling and digital image correlation. The findings suggest that evaluating composite strength based on maximum load increases the risk of premature failure.

Summary: Using large-scale classical molecular dynamics simulations, the mechanics of nano-reinforcement of graphene-based nanocomposites are investigated. The simulations show that a significant amount of defect-free, predominantly flat graphene flakes is necessary to enhance the materials properties. The results are in excellent agreement with experimental and proposed continuum shear-lag theories. The optimal critical lengths for enhancement are approximately 500 nm for graphene and 300 nm for graphene oxide (GO). The simulations also suggest that aligned and planar flakes are crucial for optimal reinforcement, as undulations degrade the enhancement of materials properties.
