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...

Article describes methods and results of experimental research for strain behavior, crack formation fracture concrete beams reinforced with fiber polymer (FRP) bars during bending moment action. 18 (3+3 series) glass FRP (GFRP) basalt (BFRP) 6, 10 14 mm in diameter were tested. Deflection the middle beam, ultrasonic transmission time 4 routes measured tests besides visual inspection. Main occur...

Abstract One of the major advantages using glass fiber-reinforced polymer bars as a replacement to traditional steel-reinforced is its lightweight and high-resistant corrosion. This research focuses on performance concrete beams partially/fully reinforced with 50% GFRP were used reinforce partially at flexural zone. While 100% fully compression zones different compressive strength. study report...

Abstract In this paper, pultruded GFRP bars are investigated to determine their fracture properties. The double cantilever beam test (DCB) is used assess behavior under mode I loading conditions. However, due the presence of R-curve effect (variable energy dependent on length crack), it necessary introduce a nonstandard approach mixed experimental–numerical proposed deal with issue. Numerical s...

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 ...

A finite element model (FEM) was constructed using specialized three-dimensional (3D) software to investigate the punching shear behavior of interior slab-column connections subjected to a moment-to-shear ratio of 0.15 m. The FEM was then verified against the experimental results of full-scale interior slab-column connections reinforced with glass fiber reinforcement polymer (GFRP) bars previou...
