Flexural strength and modulus of woven glass fiber-reinforced specimens werc significanLly greater than those without woven glass fiber (p<O.OD, Likewise, comprossive strength of reinforced specimens was signifieantly greater than those without woven glass fiber (p<O.Ol), except for specimens rcjnforced with woven glass fiber oriented at a tilt directio...

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...

Abstract. In this paper we derive bounds on the torsional rigidity for coated fiber reinforced shafts. The bounds are used to assess the optimality or suboptimality of fiber reinforcement configurations. This investigation focuses on coated fiber reinforcements with circular cross section. It is shown how the effective antiplane shear modulus and torsional rigidity of each coated fiber are used...

This study conducts physicochemical mechanical characterization plaster material intended for application in sector. developed contains potassium polyacryl...

A concise state-of-the-art survey of fiber-reinforced polymer ~also known as fiber-reinforced plastic! composites for construction applications in civil engineering is presented. The paper is organized into separate sections on structural shapes, bridge decks, internal reinforcements, externally bonded reinforcements, and standards and codes. Each section includes a historical review, the curre...

This paper describes an investigation on the use of a new composite construction material composed of plaster, sand, crushed gravel and date palm fibres of waste agriculture peels, having mechanical properties potentially useful in technical domains. Thermal conductivity and some mechanical and physical properties are investigated. The results showed that the incorporated vegetable fibres chang...

Environmental awareness today motivates the researchers, worldwide on the studies of natural fiber reinforced polymer composite and cost effective option to synthetic fiber reinforced composites. The availability of natural fibers and ease of manufacturing have tempted researchers to try locally available inexpensive fibers and to study their feasibility of reinforcement purposes and to what ex...

Using strong fibers to reinforce a hydrogel is highly desirable but difficult. Such a composite would combine the attributes of a solid that provides strength and a liquid that transports matter. Most hydrogels, however, are brittle, allowing the fibers to cut through the hydrogel when the composite is loaded. Here we circumvent this problem by using a recently developed tough hydrogel. We fabr...

introduction: post and core has been considered for endodontically treated tooth, especially in cases with severe damage crowns. recently fiber reinforced composite posts (frc post) have been used in the treatment of endodontically treated teeth. because the length and diameter of posts are effective in stress distribution, the purpose of this study is to evaluate the effect of length and diame...

the present paper offers a meso-scale numerical model to investigate the effects of random distribution of aggregate particles and steel fibers on the elastic modulus of steel fiber reinforced concrete (sfrc). meso-scale model distinctively models coarse aggregate, cementitious mortar, and interfacial transition zone (itz) between aggregate, mortar, and steel fibers with their respective materi...
