Vacuum assisted resin transfer moulding (VARTM) is a promising manufacture process for making large and complex fiber reinforced composite structures. However, the complexity of the flow of the resin in the infusion stage usually leads to nonuniform property distribution of the produced composite part. In order to control the flow of the resin, the situation of flow should be mastered. For the ...

Influence of reinforcement effect on mechanical properties of banana bio fiber polyester has been investigated. Three different type of weaving patterns such as plain, basket and twill banana fabric were used to analyze the mechanical properties of composites. Results revealed that composite with basket weaving style enhances the properties of composite material compared to other two patterns. ...

The use of composite materials is an effective technique to enhance the capacity of reinforced concrete columns subjected to the seismic loading due to their high tensile strength. In this paper, numerical models are developed in order to predict the experimental behavior of square reinforced concrete columns strengthened by glass fiber reinforced polymer and steel bars and unstrengthened colum...

Recent advancements in metal fibers have introduced a promising new type of stainless steel fiber with high stiffness, high failure strain, and a thickness < 100 μm (<0.00394 in.) that can be utilized in a steel fiber-reinforced polymer. However, stainless steel is known to be susceptible to pitting corrosion. The main goal of this study is to compare the impact of corrosion on the mechanical p...

introduction: glass-ionomer cements (gics) are one of the most important dental restorative biomaterials. the aim of this study was to synthesize glass-ionomer‒silk fiber composite and evaluate the effect of adding natural degummed silk fiber on the bioactivity and the ability to release fluoride by glass-ionomer cement. materials and methods: in this study, commercial fuji ii glass-ionomer cem...

This paper presents the micromechanical modeling of fiber bridging constitutive law of a discontinuous fiber reinforced composite (DFRC) under cyclic loading. Fiist, the derivation of fiber bridging constitutive law under monotonic loading is briefly reviewed to highlight he approach to obtain the bridging stress carried by randomly distributed discontinuous fibers. Second, the relation between...

Introduction: Fluid composites have been suggested as gingival layer beneath class II composite restorations to improve marginal integrity and reduce microleakage. This in-vitro study evaluated the influence of fluid composites as gingival layer on microleakage of class II packable, microhybrid, and fiber-reinforced composite restorations with the margins below the cementoenamel junc-

Natural fiber-reinforced composites can contribute to reducing carbon footprint goals due their ability reduce overall product weight, bio-diverse feedstocks, and recyclability potential. In this work, natural fiber-based containing the reinforcement of coconut husk bagasse fiber with calcium carbonate (CaCO3) ingredients were prepared analyzed. The analyzed for mechanical, thermomechanical, mo...

The purpose of this study was to investigate the reinforcing effect of short E-glass fiber fillers oriented in different directions on composite resin under static and dynamic loading. Experimental short fiber-reinforced composite resin (FC) was prepared by mixing 22.5 wt% of short E-glass fibers, 22.5 wt% of resin, and 55 wt% of silane-treated silica fillers. Three groups of specimens (n=5) we...
