The marine composites market is driven by the increasing demand for lightweight, corrosion-resistant, and impact-resistant boats. Polymer matrix are currently most popular composite material in applications. Fiberglass practically main type of fiber that used extensively Due to aggressive sea environment, structural elements ships exposed damage due phenomenon osmosis. This also favored defects...

A nonlinear and nonadditive composition-dependent change of the ionic conductivity in mixed glass-former (MGF) glasses when one glass former, such as PS(5/2), is replaced by a second glass former, such as GeS2, at constant alkali modifier concentrations, such as Na2S, is known as the mixed glass-former effect (MGFE). Alkali ion conducting glasses are of particular interest for use as solid elec...

In this work, we report the potential use of novel carbon nanofibers (CNFs), dispersed during fabrication of glass fiber composites to monitor damage propagation under static loading. The use of CNFs enables a transformation of the typically non-conductive glass fiber composites into new fiber composites with appreciable electrical conductivity. The percolation limit of CNFs/epoxy nanocomposite...

This paper is an experimental study of the effectiveness using internal and external alkali-resistant glass fabric textile (AR-GT) layers for flexural strengthening reinforced concrete (RC) beams. The work compares single triple AR-GT as supplemental reinforcement with textile-reinforced mortar (TRM) in RC beams subjected to four-point bending loading. In addition, a control beam specimen cast ...

The scientific community is shifting its focus towards construction materials with a low carbon footprint, such as alkali-activated concrete (AAC). present study conducts an environmental impact assessment using the cradle-to-grave approach to examine implications of three different types ambient-cured AACs varied combinations precursors. 28-day compressive strength values mixes used for compar...

The term “glass fiber” as used here refers to any rigid, vitreous fiber, mineral or organic. “Glass” is a physically defined state of matter and not a product with a specific chemical composition. To cause health complaints it must be large enough to be trapped by the upper respiratory system. Crystalline fibers, such as the asbestos minerals and other fibrous minerals and vitreous fibers that ...

The design and fabrication of a tellurite glass multimode optical fiber for magneto-optical applications are presented and discussed. The analysis of the polarization shows that an optical beam, linearly polarized at the fiber input, changes to elliptically polarized with an ellipticity of 1∶4.5 after propagating down the fiber. However, the elliptical distribution remains unchanged with or wit...

The influence of the fiber used as reinforcement in resin matrix composite materials submitted to repeated low energy impacts is analyzed. The aramid, glass and carbon fiber composites were submitted to drop weight tests from 0.5m and from 1m. The number of impact events necessary to cause failure was recorded, and the fracture characteristics of each composite were analyzed by optical microsco...
