Developments in fiber-reinforced polymer (FRP) composites for civil engineering by N. Uddin,A.M. Abro,J.D. Purdue,U. Vaidya Pdf

Abstract: The primary objective of this chapter is first to introduce and demonstrate the application of thermoplastic (woven glass reinforced polypropylene) in the design of modular fiber-reinforced bridge decks, and next the development of jackets for confining concrete columns against compression and impact loading. The design concept and manufacturing processes of the thermoplastic bridge deck composite structural system are presented by recognizing the structural demands required to support highway traffic. Then the results of the small-scale static cylinder tests and the impact tests of concrete columns are presented, demonstrating that thermoplastic reinforcement jackets act to restrain the lateral expansion of the concrete that accompanies the onset of crushing, maintaining the integrity of the core concrete, and enabling much higher compression strains (compared to CFRP composite wraps) to be sustained by the compression zone before failure occurs.

This chapter presents a systematic approach for material characterization, analysis, and design of all-fiber-reinforced polymer or plastic (FRP) composite structures. The suggested ‘bottom-up’ analysis concept is applied throughout the procedure, from materials/microstructures, to macro components, to structural members, and finally to structural systems, thus providing a systematic analysis methodology for all-FRP composite structures. The systematic approach described in this chapter can be used efficiently to analyze and design FRP shapes and bridge systems and also develop new design concepts for all composite structures.

Biofibers are emerging as a low cost, lightweight and environmentally superior alternative in composites. Generally, different fibers exhibit different properties that are fundamentally important to the resultant composites. This chapter gives an overview of the most common biofibers in biocomposites, covering their sources, types, structure, composition, and properties. Drawbacks of biofibers, such as dimensional instability, moisture absorption, biological, ultraviolet and fire resistance, will be discussed. The chapter will focus on their modifications (physical and chemical methods), matrices based on their petrochemical resources and bio-based, processing of biofiber reinforced plastic composites covering the factors influencing processing (humidity, additives, machinery, processing parameter, fiber content and length), and processing techniques (compounding, compression molding, extrusion, injection molding, pultrusion and others) will be discussed. The properties of the biocomposites based on their mechanical, physical, and biological behavior will also be covered. Lastly, this chapter concludes with recent developments and trends of biocomposites in the near future in civil engineering.

Developments in fiber-reinforced polymer (FRP) composites for civil engineering by J. Wang Pdf

Strengthening reinforced concrete (RC) members using fiber reinforced polymer (FRP) composites through external bonding has emerged as a viable technique to retrofit/repair deteriorated infrastructure. The interface between the FRP and concrete plays a critical role in this technique. This chapter discusses the analytical and experimental methods used to examine the integrity and long-term durability of this interface. Interface stress models, including the commonly adopted two-parameter elastic foundation model and a novel three-parameter elastic foundation model (3PEF) are first presented, which can be used as general tools to analyze and evaluate the design of the FRP strengthening system. Then two interface fracture models – linear elastic fracture mechanics and cohesive zone model – are established to analyze the potential and full debonding process of the FRP–concrete interface. Under the synergistic effects of the service loads and environments species, the FRP–concrete interface experiences deterioration, which may reduce its long-term durability. A novel experimental method, environment-assisted subcritical debonding testing, is then introduced to evaluate this deteriorating process. The existing small cracks along the FRP–concrete interface can grow slowly even if the mechanical load is lower than the critical value. This slow-crack growth process is known as environment-assisted subcritical cracking. A series of subcritical cracking tests are conducted using a wedge-driven test setup t o gain the ability to accurately predict the long-term durability of the FRP–concrete interface.

This chapter discusses design for fiber-reinforced polymer (FRP)/autoclaved aerated concrete (AAC) sandwich panels for structural applications. The chapter first presents the finite element analysis (FE) of FRP/AAC panels. The FE results are compared with the experimental results showing acceptable agreement. Next, analytical models are presented to predict the deflection and strength of the panels. Finally, design graphs have been developed to help in designing the floor and wall panels made from FRP/AAC panels. Also, those panels have been compared to the commercially used reinforced AAC panels demonstrating that FRP/AAC panels offer a relatively cost-effective solution for longer life cycle.

Developments in fiber-reinforced polymer (FRP) composites for civil engineering by N. Uddin,A. Vaidya,U. Vaidya,S. Pillay Pdf

Modular panelized construction is a modern form of construction technique in which precast multifunctional structural panels are used. In this technique, precast panels are fabricated in the manufacturing facility and are transported to the construction site. Traditional structural insulated panels (SIPs) consist of oriented strand boards (OSB) as facesheets and expanded polystyrene (EPS) foam as the core. These panels are highly energy efficient but have issues in terms of poor impact resistance and higher life cycle costs. Proposed panels consist of E-glass/polypropylene (PP) laminates as facesheets and EPS foam as core and are called composite structural insulated panels (CSIPs). Proposed CSIPs overcome the issues of traditional SIPs and retain all the energy-saving benefits of the traditional SIPs. This chapter describes manufacturing techniques developed for CSIPs and connection details for bonding CSIPs on the construction site. Based on the experimental investigation, ultrasonic welding was found to be the most suitable technique for joining the proposed CSIPs.

High-quality and expedient repair methods are necessary to address concrete deterioration that can occur in bridge structures. Most infrastructure-related applications of fiber-reinforced plastics (FRPs) use hand layup methods. Hand layup is tedious, labor-intensive and results are sensitive to personnel skill level. An alternative method of FRP application is vacuum assisted resin transfer molding (VARTM). VARTM uses single-sided molding technology to infuse resin over fabrics wrapping large structures, such as bridge girders and columns. There is no research currently available on the interface developed, when VARTM processing is adopted to wrap fibers such as carbon and/ or glass over concrete structures. This chapter investigates the shear and flexural strength gains of a beam by carbon fiber cast on concrete using the VARTM method. The carbon fiber composite was made using Sikadur HEX 103C and low viscosity epoxy resin Sikadur 300. Tests were conducted to determine and document the gains of FRP rehabilitated beams applied by the VARTM method compared to the hand layup method of application. This newly introduced technique to repair and retrofit a simple span I-565 prestressed concrete bridge girder in Huntsville, Alabama, was implemented in the field within two days without any traffic interruption, and the field demonstration of this newly introduced technique to civil infrastructure is presented to the end.
