Book Description
Fibre-reinforced polymer (FRP) composites are increasingly being used in the field of civil engineering, either for the rehabilitation/retrofitting of existing infrastructures or for the construction of new structural elements. However, such applications are still recent and there are still unresolved questions regarding the long-term durability of FRP reinforcements or structural elements under service conditions, and their behaviour under accidental fire events as well. In this chapter, it is proposed to highlight the basic mechanisms involved in the environmental degradation of FRP composites, with a large emphasis on ageing mechanisms of the polymer matrix and their consequences on the mechanical properties. The last section is specifically devoted to the fire behaviour of polymer composites and also recalls existing fire-proofing solutions.

Book Description
The term liquid composite moulding (LCM) encompasses a family of processes in which a dry fibrous reinforcement is impregnated by a liquid resin inside a sealed cavity. As the understanding and control of these processes improve, their field of application widens. LCM processes can be used as a replacement to decrease the environmental impact and improve the quality of composite parts made via traditional open-mould processes. they can also provide a cost-cutting alternative to prepreg techniques while maintaining a high part quality. This chapter describes the variety of processes blanketed under the class liquid composite moulding and the research advances in the monitoring and simulation of these processes. the subsequent section presents the current usage of LCM techniques in the field of civil engineering, including some case studies, before outlining some future trends and offering sources for further information.

Book Description
This chapter focuses on the properties, manufacturing processes and quality control of pultruded advanced composites used in civil engineering applications. Pultrusion technology is first briefly explained, with the main features of the raw materials used being introduced, and the philosophy underlying the development of pultruded advanced composites discussed. A detailed description of the pultrusion process then follows, covering the equipment and procedure, technical specifications and quality control. Subsequently, the types, properties, applications and sustainability of pultruded profiles, reinforcing bars and strengthening strips are described. The final part of the chapter discusses future trends for the pultrusion of the advanced composites used in civil engineering applications.

Book Description
In this chapter, we report the findings of experimental investigations conducted on durability of glass fiber-reinforced polymer (GFRP) composites with and without the addition of montmorillonite nanoclay. First, neat and nanoclay-added epoxy systems were characterized to evaluate the extent of clay platelet exfoliation and dispersion of nanoclay. GFRP composite panels were then fabricated with neat/modified epoxy resin and exposed to six different conditions, i.e. hot-dry/wet, cold-dry/wet, ultraviolet radiation and alternate ultraviolet radiation–condensation. Room temperature condition samples were also used for baseline consideration. An improved dispersion of nanoclay and exfoliation of clay platelets were observed in 2wt% of epoxy samples. Weight change, discoloration and significant reduction in properties were observed in all conditioned GFRP samples. However, addition of nanoclay considerably improved the durability of GFRP samples as evident from the mechanical and micrographical results in comparison to neat samples subjected to similar conditions.

Book Description
Thermosets such as phenolic thermosets are brittle at room temperature. Thus, in applications where good mechanical properties are required thermosets must be combined with reinforcements to improve these properties. Composites based on thermoset matrices can substitute for steel and concrete in some applications of civil construction structures because of their higher resistance to oxidation than steel and better freeze–thaw resistance than concrete. Furthermore, phenolic composites can be produced with complex shapes, and with careful design, materials can be obtained with high strength and stiffness and excellent impact strength, making these materials alternatives to metals. Construction materials require fire- and high-temperature-resistant components, and moldings and laminates based on phenolics can be utilized due to their resistance to burning and minimal smoke and toxic fumes production. Phenolic composites can positively impact the building and construction industry by improving safety and reducing cost.

Book Description
This chapter addresses all aspects pertaining to stresses inherent within civil applications of advanced composites, particularly the critical interfacial adhesive stresses usually controlling the design strength for externally bonded FRP composites. Informed discussions and explanations are presented on influential aspects closely affecting the distribution and magnitude of interfacial stresses along the bondline. Traditional and promising experimental methods for stress estimation are addressed, together with a corresponding brief literature review highlighting their evolution and practical advantages and disadvantages. Theoretical and numerical methods for interfacial stress analyses are also reviewed for different FRP bonding applications, and their stress prediction capabilities are verified with experimental validations. Finally, key conclusions and recommendations for future trends in the stress characterizations of adhesive joints are provided.

Book Description
This chapter describes the elastic qualities of advanced fibre-reinforced composites, in terms of characterization, measurement and prediction from the basic constituents, i.e. the fibre and matrix. The elastic analysis comprises applying micromechanics approaches to predict the lamina elastic properties from the basic constituents, and using classical lamination theory to predict the elastic properties of composite materials composed of several laminae stacked at different orientations. Examples are given to illustrate the theoretical analysis and give a full apprehension of its prediction capability. The last section provides an overview on identification methods for elastic proprieties based on full-field measurements. It is shown that these methodologies are very convenient for elastic characterization of anisotropic and heterogeneous materials.
