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...

A series of stress corrosion experiments were performed on 12 pultruded glass fiber composite materials (two fibers in six different matrices) commonly used in high voltage composite insulators. In this study two types of glass fibers were investigated, namely Eglass and ECR-glass. The tests were performed in nitric acid solutions (pH 1.2) using constant K I specimens that were specifically des...

This study aims to evaluate the effect of functionalized multi-walled carbon nanotubes (MWCNTs) on performance glass fiber (GF)-reinforced polypropylene (PP) for wind turbine blades. Support theoretical blade movement horizontal axis turbines (HAWTs), simulation, and analysis were performed with Ansys computer package gain insight into durability polypropylene-chopped E-glass application in bla...

Different approaches were adapted to strength the structural elements increase load capacity and reduce deformation such as deflection. The easiest light external strengthening of reinforced concrete members are Fiber Reinforced Polymer (FRP) family Armed, Carbon, Glass Basalt, respectively. This paper presents theoretical approach check out experimental tests beams strengthened by glass fiber ...

PURPOSE The aim of this study was to compare the flexural strength of polymethyl methacrylate (PMMA) and bis-acryl composite resin reinforced with polyethylene and glass fibers. MATERIALS AND METHODS Three groups of rectangular test specimens (n = 15) of each of the two resin/fiber reinforcement were prepared for flexural strength test and unreinforced group served as the control. Specimens w...

Background. Acrylic resins used in restorative dentistry are the most popular denture base material, because they have good optical properties and small solubility in body fluids. However their mechanical properties are limited and therefore acrylic resins require different methods of reinforcement one of which can be application of different kinds of fibers. Objectives. To investigate the effe...

A far-field airborne radar (FAR) nondestructive testing (NDT) technique integrating inverse synthetic aperture radar (ISAR) measurements and a backprojection algorithm for the condition assessment of glass fiber reinforced polymer (GFRP)–wrapped concrete structures is proposed. The method is directed toward the detection of near-surface defects and delaminations located in the vicinity of GFRP–...

Experimental design and response surface methodology (RSM) were used to optimize the modification of conditions for glass surface grafting with acrylamide (AM) monomer for preparation of a glass fiber reinforced poly(vinylidene fluoride) (PVDF) composite membrane (GFRP-CM). The factors considered for experimental design were the UV (ultraviolet)-irradiation time, the concentrations of the initi...
