This work evaluated the possibility of using silicon solar cells as load-carrying elements in composite sandwich structures. Such an ultra-light multifunctional structure is a new concept enabling weight, and thus energy, to be saved in high-tech applications such as solar cars, solar planes or satellites. Composite sandwich structures with a weight of 800 g/m were developed, based on one 140 l...

In the application of multiple Carbon Fiber-Reinforced Plastic (CFRP) plates onto a structural steel member, stepping of the CFRP plate ends is often adopted to prevent debonding. This approach requires the nonuniform extension of CFRP plate lengths. In this study, to shorten the length of CFRP plates, a nonuniform overlapping arrangement of several CFRP plate ends was proposed and the theoreti...

The composite pressure vessels are used in varieties of applications such as automobile, aeronautics and chemical engineering. Besides these, they have become very popular in oil and gas transport industries. These pressure vessels are experience very high internal pressures during their operation. The present paper demonstrates a study on cylindrical section of carbon fiber reinforced polymer ...

The mechanical and electrochemical performance of carbon fiber-reinforced polymer (CFRP) were investigated regarding a novel improvement in the load-carrying capacity and durability of reinforced concrete structures by adopting CFRP as both a structural strengthener and an anode of the impressed current cathodic protection (ICCP) system. The mechanical and anode performance of CFRP were investi...

In this study, a carbon nanotube (CNT) buckypaper was interleaved in carbon-fiber-reinforced polymer (CFRP) composite to improve the interlaminar fracture toughness. Interleaving film of laminate-type poses risk deteriorating in-plane mechanical properties. Therefore, shear modulus and strength were measured prior estimating To evaluate effect on toughness CFRP, double cantilever beam (DCB) end...

In the present study, non-linear finite element analyses are carried out on the slender reinforced concrete columns wrapped using CFRP composite with different cross-sectional shapes having the same area. Thickness of the CFRP wraps, concrete compressive strength, corner radius, loading condition, slenderness ratio and column size are the main parameters of this study. According to this, four d...

In this study, the scope of CFRP cables in cable-stayed bridges is studied by establishing a numerical model of a 1400-m span of the same. The mechanical properties and characteristics of CFRP stay cables and of a cable-stayed bridge with CFRP cables are here subjected to comprehensive analysis. The anomalies in the damping properties of free vibration, nonlinear parametric vibration and wind f...

This paper introduces a strengthening technique for steel monopole towers using high-modulus carbon fiber reinforced polymer (CFRP) materials. The technique is based on a theoretical and analytical investigation including testing large scale steel monopole towers strengthened with different CFRP materials and connection details. Based on the research findings, design aspects and installation pr...
