“…The largest difference can reach 50%, which indicates a significant effect of the NOL on permeability. The same conclusion was observed in other investigations . However, it is the first time that the effect has been verified for multilayer 2D woven fabrics simultaneously in numerical predictions and experimentally.…”

“…The same conclusion was observed in other investigations. [14,17] However, it is the first time that the effect has been verified for multilayer 2D woven fabrics simultaneously in numerical predictions and experimentally. According to these results, it is not recommended, especially for a low number of fabric layers and fiber volume content, to use a fixed cavity thickness and change the number of fabric layers to characterize the saturated transverse permeability as a function of fiber volume content, as commonly seen in other works.…”

The transverse permeability of fibrous reinforcement is one of the critical parameters that govern fabrication efficiency and production quality in several liquid composite molding process variants devised to achieve transverse impregnation of fibrous reinforcements. It is difficult to precisely measure and predict the transverse permeability, because it is simultaneously affected by diverse factors, for example, the geometric features of the test mold, nesting between fabric layers, and flow‐induced compaction of the fiber bed. In this article, the saturated transverse permeability of 2D woven glass fabrics is investigated using information provided by mesostructural geometric models reproducing the real textile architecture. These models are created by micro‐CT aided geometric modeling, a recently proposed technique to analyze three‐dimensional images obtained by X‐ray microtomography. They are called “material twins” because they reproduce with assessed accuracy the geometrical configuration of the textile preform, are representative of material variability, and allow performing numerical simulations of flow or mechanical properties. Computer simulations of steady state transverse flows in material twins were carried out to evaluate the transverse permeability and compared to experiments. Issues concerning material variability due to nesting and the accuracy of transverse permeability measurements were considered and discussed. A good agreement was obtained between numerical and experimental values of transverse permeability. Both approaches show a significant influence of the number of layers considered, which can be explained by nesting between adjacent plies. Numerical simulations also illustrate how nesting significantly affects material variability.

“…The ratio decreases as the number of defects in the structure increases and the distance between the layers also increases. It indicated that the anodized Ti can react with GO and cause the reduction of GO . There is not only physical adsorption between Ti and GO, but also chemical bonding.…”

“…GO is always used as a nano‐filler for different matrixes such as polymers and metals. GO is also used as enhancer in fiber‐reinforced polymer composites, because the addition of a small amount of GO significantly increases the performance of composite . When compared with chemical vapor deposition and other methods, electrophoretic deposition (EPD) is much more economical and easy to implement.…”

This article discusses about the significance of graphene oxide (GO) deposition on the surface of a titanium plate by electrophoretic deposition (EPD) method to improve the adhesive strength of Ti/polyetheretherketone (PEEK) interfacial adhesive. Firstly, the anodic EPD method was applied to a water dispersion solution of GO, and then the morphology and the properties of titanium plate surface were characterized by scanning electron microscopy and contact angle measurements before and after GO deposition. Furthermore, the changes in the properties of GO after heating at 390°C were characterized by Raman and Fourier transform infrared spectroscopies. According to the results of single lap tensile shear test, the adhesion strength of Ti/PEEK interface after the anodization and deposition of GO was 34.94 MPa, an increase of 29.2% compared with 27.04 MPa of sample with only anodization. Also, the adhesion strengths were 58.1 and 76.5% higher compared with the samples of only GO deposited (22.1 MPa) and pure titanium (19.8 MPa), respectively. POLYM.
