Abstract Anchor heads could efficiently address the bond weakness between Fibre-Reinforced Polymer bars and concrete. This experimental study enhanced behaviour GFRP concrete using three innovative anchorage systems made from glass fibre cloth epoxy resin. A direct pullout test was used to bond-slip performance bar Test variables were diameter (3 diameters), compressive strength (20.4 40.2 MPa)...

Due to the assumption of uniform bond stress, development length fibre reinforced polymer (FRP) bars by design standards can be unnecessarily long and difficult provide in practice. Hence, stress distribution required a glass (GFRP) rebar is investigated. Four beam-bond specimens, two following RILEM specifications based on procedure ACI are tested evaluate effect test method strength. Ten pull...

design of bridge deck with long-term strength, durability and permanence is a significant interest for engineers. one applicable solution to this challenge could be via using hybrid system consisting of conventional materials such as concrete and steel with frp plates which is also known as composite deck. since these deck are relatively new so their performance is not completely known. the pre...

Recently in Thailand, the recycling process of waste printed circuit board (WPCB) has retained a large volume of nonmetallic fraction (NMF), which has entered the industrial waste stream and awaits an appropriate treatment to be suggested. The aim of this paper was to assess environmental impacts of the recycled nonmetallic fraction from waste printed circuit board in Thailand, using the ReCiPe...

Abstract— Due to the superior physical and mechanical properties Glass fiber-reinforced (GFRP) composite materials are very attractive for applications like aerospace and air craft structural components. This results a large number of research papers on machining of these composite laminates. Out of all the machining operations, most commonly used operation is drilling. However, drilling operat...

The plate of a pultruded fiber-reinforced polymer or fiber-reinforced plastic (FRP) profile produced via a pultrusion process is likely to undergo local buckling and cracking along the fiber direction under an external load. In this study, we constructed a pultruded glass-fiber-reinforced polymer-light wood composite (PGWC) profile to explore its mechanical performance. A rectangular cross-sect...

The fine-grained soil including the problematic ones can cause many difficulties in project accomplishment. Settlement and swelling are among the problems of the fine-grained soils. The present study compared the effects of the polypropylene waste plastic (PWP) and glass fiber reinforced polymer (GFRP) on geotechnical properties of the clayey soils for the subgrade design. To this end, the PWP ...

INTRODUCTION Optimization of machining parameters is essential for improving expected outcome of any machining operation. CASE DESCRIPTION The aim of this work is to find out optimum values of machining parameters to achieve minimal surface roughness during milling operation of GFRP. DISCUSSION AND EVALUATION In this machining operation speed, depth of cut and feed rate are considered as pa...
