Abstract:
Carbon fiber reinforced polymer (CFRP) composites are increasingly being used to strengthen structures and to retrofit existing structures. CFRP composites are used in various industries: construction, automotive, and many others. This literature review has shown that CFRP composites find numerous practical applications. Improving structures by reinforcing them with CFRP composite is an innovative approach in design. This review aims to explore the current state of the art in the types of structures that can be reinforced with CFRP, and modifications to the CFRP composite as an additional aspe

Sandwich structural composites (CFRP/ABS/CFRP) of inexpensive acrylonitrile butadiene styrene (ABS) cores (2.0 mm thickness) between carbon fiber reinforced epoxy (CFRP) laminate plies (2.5 mm thickness) were suggested and prepared, since the materials cost of ABS resin was about 8% that of CFRP. Although Young’s modulus of CFRP/ABS/ CFRP is slightly smaller than that of CFRP, Charpy impact value (auc) of the CFRP/ABS/CFRP approximately corresponded to that of CFRP composite. Furthermore, applying homogeneous low voltage electron beam irradiation (HLEBI) to both side surfaces improved theaucof

Abstract:
Abstract The galvanic interactions between AA2024 and Carbon Fiber Reinforced Polymer under a dynamic drop of NaCl electrolyte were studied. The use of a dynamic electrolyte provided the unique opportunity to investigate both thick and ultra-thin electrolyte systems. A modeling approach was achieved by solving the Nernst-Planck equations in a 2D dynamic domain. Two kinds of boundary conditions were considered: electrochemical and physicochemical. Huge differences were found in the galvanic corrosion process at the beginning of the droplet evaporation (initial height 1.8 mm) and after 24 h of a

Abstract:
Abstract In a range of industrial sectors, multi-material constructions are used to optimise the performance of structures. In the transport sector, metal-to-carbon fibre reinforced polymers (CFRP) and steel-to-aluminium joints are seeing a dramatic growth in both R&amp;D activity and commercial applications. As these materials are not weldable, directly to one another, current industrial joining solutions involve the use of mechanical fastening and adhesives. These dissimilar material combinations are highly susceptible to corrosion, because of the galvanic coupling between parent materials w

Abstract The use of cured-in-place pipe (CIPP) and Carbon Fiber Reinforced Polymer (CFRP) liners for the rehabilitation of nuclear power plant raw water systems can result in significant cost savings, increased system reliability, and extended piping life. These systems also include the use of internal mechanical seals. The cost advantage for installation of CIPP alone may reach 10:1 for the nuclear power industry versus excavation and replacement of buried carbon steel piping. This paper will present recent examples of these applications, including unique requirements faced in the nuclear ind

Abstract Over the last 30 years high performance advanced FRP composites, originally introduced in aerospace, have become widespread in the marine and alternative energy industries, and are now becoming increasingly used in civil and architectural projects. The use of composite materials in new fields still represents a challenge due to the higher percentage of defects in final manufactured composite parts. This requires a closer look of the mechanical properties of the composite materials considered to ensure safety requirements and overall structural integrity is achieved. A variety of advan

Abstract:
Abstract Carbon fiber reinforced plastic prestressed concrete (CFRPC) is a material that utilizes CFRP strand cables as tendons, exhibiting exceptional performance in terms of specific stiffness, strength, and high corrosion resistance [1]. Particularly when used in offshore structures, it is considered to overcome the drawbacks of steel strand cables [2]. In this study, we propose the use of fiber-optic sensors to assess the structural integrity when considering the application of CFRPC to long-life offshore structures. We perform two experiments. First, we conduct tensile tests on three type

Abstract:
Many steel structures are susceptible to fatigue loading and damage that potentially threaten their integrity. Steel hydraulic structures (SHS) experience fatigue loading during operation and exposure to harsh environmental conditions that can further reduce fatigue life through stress corrosion cracking and corrosion fatigue, for example. Dewatering to complete inspections or repairs to SHS is time consuming and leads to economic losses, and current repair methods, such as rewelding, often cause new cracks to form after relatively few cycles, requiring repeated inspection and repair.

Recent advances in the use of fiber-reinforced polymers (FRP) to retrofit steel structures subjected to fatigue cracks have shown to be a viable solution for increasing fatigue life in steel hydraulic structures (SHS). Although several studies have been conducted to evaluate the use of FRP for retrofitting metal alloys and the promising potential of such has been well-demonstrated, the application has never been implemented in underwater steel structures.

The EU’s Common Foreign and Security Policy (CFSP) is subject to “specific rules and procedures” that seem to stand in the way of its effectiveness. This Working Paper assesses the special legal nature of the CFSP and explores the legal possibilities to enhance decision-making procedures. It argues that current EU Treaties should not necessarily be amended to achieve better outcomes. In fact, the Treaty on European Union (TEU) provides for some “sleeping beauties” that have rarely been used.

Delayed, or even vetoed, decisions on the EU’s Common Foreign and Security Policy (CFSP) have marred the efficiency of decision-making in CFSP for years – and by extent, they hinder the EU on its path to becoming a more assertive global actor. This brief shows realistic options the EU can use to implement more qualified majority voting (QMV) in the CFSP and closely related policy areas. In addition to activating underused CFSP Treaty provisions, the EU could boost its use of trade, and to some extent, internal competences – and thereby QMV – to pursue CFSP objectives. 1.

Although steel hydraulic structures have a protective system to prevent corrosion, this type of deterioration will eventually occur due to the constant exposure to harsh environmental conditions. There are several techniques that can be implemented to repair corroded steel structural elements.

Steel elements working in a harsh environment can be exposed to corrosion that degrades their performance and threatens the integrity of the whole structure. Recent studies propose using carbon (CFRP) and basalt (BFRP) fiber–reinforced polymers to repair corroded steel cross sections; however, most of these studies have not explored many of the structural characteristics, including ductility. In this study, we conduct a series of full-scale experimental tests to investigate the impact of corrosion, represented as mechanical section reduction, on steel beams as well as the impact of repairing t

The project aims to address the need for an inorganic coating composite for corrosion protection of pipelines in an aggressive environment. The inorganic coating does not generate CO2 emission or volatile organic content (VOC). Inorganic coatings are frequently used in the construction industry as anti-corrosion coatings, which are effective, chemically inert, hard, and thermally stable. In this study, microfiber reinforcement and Nano-modification were used to improve the performance of the inorganic coating system.
