Interlaminar failure of bonded composite structures is quite often. Nowadays there a lot lightweight high reliability carbon or glass fiber (CFRP GFRP) reinforced polymer constructions with rods. In order to better understand the delamination processes rods, analytical equations were analyzed. Later, mode I interlaminar experiments CFRP rods 3x3 mm performed and fracture toughness GIC = 135 J/m...

This article reports the finite element (FE) investigation of axial capacities pultruded fiber-reinforced polymer (PFRP) composite channel columns. The nonlinear model (FEM) was developed by using ABAQUS package for glass (GFRP) columns, which included geometric and initial imperfections. FEMs were verified against an experimental result available in literature GFRP validated used to carry out ...

The purpose of this study was to propose a new numerical modeling of the glass fiber cloth reinforced denture base resin (GFRP). The proposed model is constructed with an isotropic shell, beam and orthotropic shell elements representing the outmost resin, interlaminar resin and glass fiber cloth, respectively. The proposed model was applied to the failure progress analysis under three-point ben...

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–...

The axial compressive strength of unidirectional FRP made by pultrusion is generally quite lower than its axial tensile strength. This fact decreases the advantages of FRP as main load bearing member in engineering structure. A theoretical iterative calculation approach was suggested to predict the ultimate axial compressive stress of the combined structure and analyze the influences of geometr...

In this study, twenty glass fiber reinforced polymer (GFRP) reinforced concrete specimens were modelled using finite element method to predict the effect of GFRP compressive bars on the flexural strength and ductility of GFRP reinforced concrete beams. Also, the contribution of GFRP longitudinal rebars to the load-carrying capacity of reinforced concrete columns is determined. The concrete elas...

In line with technological advancements, the construction industry worldwide has sought more efficient building systems in relation to aspects such as increased productivity, reduced material waste and meeting growing demand. The objective of this research was use structural joints composed composite dowels laminated wood beams an alternative connect pieces wood. Composite materials are a matri...

The effects of acid treatment, vapor grown carbon fiber (VGCF) interlayer and the angle, i.e., 0° and 90°, between the rolling stripes of an aluminum (Al) plate and the fiber direction of glass fiber reinforced plastics (GFRP) on the mode II interlaminar mechanical properties of GFRP/Al laminates were investigated. The experimental results of an end notched flexure test demonstrate that the aci...
