Summary: This study focuses on modeling transient incompressible two-phase flow during vacuum assisted resin transfer molding (VARTM) in the presence of high permeability media (HPM). A novel depth-averaged technique coupled with level set is introduced to capture the characteristics of the preform, such as compaction and permeability.

Summary: This study aims to investigate the effect of graphene nanoplatelets (GNPs) coating on the deformation modes of carbon fiber-reinforced polymer (CFRP) composites under flexural loading. The results showed that GNP-coated CFRPs had an increase in compressive modulus and failure strain, and the measured strains were higher. Nano-indentation tests also revealed a thicker interface region between the GNP coating and the fibers. Additionally, GNP-coated CFRPs exhibited improved flexural strength, flexural modulus, and strain distribution compared to uncoated CFRPs.

Summary: In this study, a novel fiber-optic biosensor was developed and tested for label-free detection of C-reactive protein in serum. The device showed enhanced sensitivity and visibility of grating resonances by tuning the working point to the mode transition region through etching of the outer fiber cladding. Coating the fiber transducer with graphene oxide enabled covalent immobilization of the biological recognition element, resulting in a low detection limit and a wide working range of clinical relevance.

Summary: The study investigated the effect of hybrid carbon nanofillers on the electrical and flexural properties for an epoxy matrix and basalt fiber reinforcing composite subjected to seasonal water absorption. Results showed minimal changes in mechanical properties after environmental ageing. Nanomodified BFRCs exhibited slightly higher effects on flexural characteristics due to higher defectiveness. Nanocomposites showed higher electrical conductivity, with UD BFRC/NC showing significantly improved conductivity after hydrothermal ageing, enhancing damage monitoring capabilities.

Summary: This study investigates the effects of strain rate and filler content on the compressive behavior of aeronautical grade RTM6 epoxy-based nanocomposites. Results show a significant increase in compressive strength with higher strain rates, while the elastic modulus and Poisson's ratio remain independent of strain rate. Addition of silica nanoparticles marginally increases the resin's glass transition temperature and enhances its moduli and peak yield strength, while the size and surface functionalization of the filler have no effect on the resin's compressive behavior at different strain rates.

Summary: This study aims to investigate the mechanical behavior of a repaired aeronautical composite stiffened panel subjected to compressive loading conditions through numerical and experimental methods. Finite element models were introduced in the ABAQUS FEM environment to simulate the mechanical behavior of the repaired panel. Experimental testing was also performed on the repaired panel to validate the numerical models. The validated numerical model was then used to analyze the compressive behavior of repaired stiffened panels with different patch stacking sequences and sizes to assess their influence on the panel's mechanical behavior.

Summary: The current study investigates the role of reactive oxygen species (ROS) in the bioeffects of different types of magnetite nanoparticles (MNPs) - bare (Fe3O4), humic acids (Fe3O4-Ha), and 3-aminopropyltriethoxysilane (Fe3O4-APTES) modified MNPs. The study found that Fe3O4-HA MNPs had the lowest amount of Fe2+ ions, while Fe3O4-APTES MNPs had the highest amount of Fe2+ ions. Bioluminescent cellular and enzymatic assays were used to monitor the toxicity and antioxidant activity of the MNPs. The results showed that the modified MNPs had toxic effects at higher concentrations (>10(-2) g/L) and stimulated ROS production by bacteria in a wide concentration range (10(-15)-1 g/L).

Summary: This study investigates the effect of different mixing techniques on the thermal and mechanical properties of graphene nanoplatelets and graphene nanofibers loaded epoxy nanocomposites. Results show that ultrasonication and fluidized bed method achieve the most suitable dispersion, resulting in nanocomposites with the largest increase in glass transition temperature. The fracture toughness of the nanocomposites is improved due to the homogeneity and low scale dispersion of the carbonaceous nanostructures. The fluidized bed method is found to be the most suitable for high volume industrial production. Carbon fiber reinforced composites manufactured using this method demonstrate improved tensile, flexural, and interlaminar fracture toughness properties.
