The aim of this study was to synthesis of glass ionomer-silk fiber composite and to evaluate the effect of adding natural degummed silk fiber on the mechanical properties of glass ionomer cement (GIC). For this purpose, natural degummed silk fibers with 1 mm in length and 13-16 µm in diameter were added to the ceramic component of a commercial glass ionomer cement in 1, 3 and 5 wt. %. Compressi...

Fiber reinforced polymer (FRP) bars are being widely used in civil engineering applications to replace steel due their excellent durability. Existing research on the durability of FRP mainly focuses glass fiber (GFRP) and basalt (BFRP) bars. Different conclusions have been drawn differences fibers, resins, volume fractions, solution concentrations, aging temperatures adopted by researchers. Som...

different glasses suitable for temperature sensing in the fiber optic sensors were studied in this article. the phase changes for eight different glass materials were calculated and results were compared. our results showed that extra dense flint glass is the most sensitive one, while pure silica results in the lowest phase change. in another study the effect of wavelength on the phase variatio...

Concrete is a worldwide construction material, but it has inherent faults, such as low tensile strength, when not reinforced with steel or other forms of reinforcement. Various innovative materials are being incorporated into concrete to minimise its drawbacks while concurrently improving dependability and sustainability. This study addresses the research gap by exploring enhancing utilisation ...

promotion of the dietary fiber of foods can enhance human health by reducing the risk of many serious diseases. cakes are among the highly consumed foods but sadly of low fiber content. therefore, increasing the fiber content in them is of great importance, and this was the aim followed in this study. wheat flour was partially replaced at 0, 10, 20 and 30% (w/w) with corn resistant starch (rs),...

background: scuba diving is one of the fastest growing sports in the world. the objective of this study was to evaluate the effect of pressure variations to which divers are exposed on the pull out strength of glass fiber post luted with different cements. materials and methods: in this in vitro study, 120 extracted, single-rooted lower premolars were endodontically treated. they were randomly ...

This study investigated the effects of high temperature exposure on the compressive, tensile, and flexural strengths of concrete containing glass fiber. A total of 108 cubic specimens (150 mm × 150 mm × 150 mm), cylindrical specimens (300 mm × 150 mm), and prismatic specimens (500 mm × 150 mm × 150 mm) were prepared for compressive, tensile, and flexural strength testing, respectively. The spec...
