This paper presents the experimental self-healing investigations on fiber-reinforced polymer (FRP) composites using a novel in-situ healing approach. During the preparation of polymer composites, the monomer Dicyclopentadiene (DCPD) was embedded as the healing agent. The compartment hollow glass microcapillaries were used to serve the localized distribution of the healing agent. To determine the viability of the proposed microcapillary approach, several flexural tests were conducted to initiate the damage and subsequent realization of self-repair activity. The healing was initiated through the polymerization of DCPD in the presence of Grubb’s catalyst (first and second generation). Once healed, the specimens were tested cyclically to evaluate the recovery of flexural strength. A post-failure healing efficiency as high as 72% has been observed. SEM and XRD investigations have been conducted for the microstructural investigations. These investigations support the potential applications of the proposed concept of embedding the bulk with the microcapillaries.

Externally bonded fiber-reinforced polymer composites have been in use in civil infrastructure for decades, but their long-term performance is still difficult to predict due to many knowledge gaps in the understanding of degradation mechanisms. This paper summarizes critical durability issues associated with the application of fiber-reinforced polymer (FRP) composites for rehabilitation of concrete structures. A variety of factors that affect the longevity of FRP composites are discussed: installation, quality control, material selection, and environmental conditions. Critical review of design approaches currently used in various international design guidelines is presented to identify potential opportunities for refinement of design guidance with respect to durability. Interdisciplinary approaches that combine materials science and structural engineering are recognized as having potential to develop composites with improved durability.

Fiber Reinforced Polymer Composites

Nowadays, fiber-reinforced polymer composites have played a significant role in many different fields of applications, regarding their high specific strength and high modulus. The fiber which serves as reinforcement mechanism in polymer composites may be either synthetic or natural. Natural fibers are not only strong and lightweight but also very economical and environmental friendly. Natural fibers as reinforcement are stated to be a major step taken in promoting environmental protection and sustainability. There are many types of natural cellulose fibers but the thickest and most resistant of all commercial natural fibers, coir/coconut fiber is a coarse, short fiber extracted from the outer shell of coconuts. Coir/coconut fibers have the highest concentrations of lignin, making it most suitable for applications where slow biodegradability is required. This chapter has been written with an aim to explore the potential of the coconut/coir fiber reinforced polymer composites in terms of their performance, surface treatments/modifications and areas of application.

Fiber Reinforced Polymer Composites

There has been a growing interest to produce composite polymeric materialsusing natural fibers as reinforcement. Scientists prefer natural fiber as a reinforced material to make polymer composites due to their bio-degradability characteristics,strong mechanical properties, high specific strength, low cost, non-abrasiveand ecofriendly nature . This review presents the reported work on natural plant based fiber reinforced polymer composites with special reference to the type of natural fibers and host polymers. Various fiber treatments, which are carried out to improve the fiber– hostadhesion, improved mechanical properties that greatly increase the application of these polymer composites specially in automobile industries and bioapplications are highlighted.

AbstractThe design of hybrid structure offers an attractive solution to enhance strength and structural stiffness as well as to achieve lightweight effect and cost reduction. The applications of steel–FRP (fiber-reinforced polymer) composites in transportation and civil engineering have been comprehensively reviewed. In order to apply hybrid structures to car body parts such as B-pillar, flexural performance of steel–FRP composites is investigated by means of three-point bending test in this study. An analytical model is deduced to calculate the initial stiffness, the bending load and the energy absorption of steel–FRP composites. Steel–CFRP (carbon fiber-reinforced polymer) and steel–AFRP (aramid fiber-reinforced polymer) composites are experimentally studied and discussed. The results demonstrate that the steel–FRP composites exhibit significantly higher load-carrying capabilities and initial stiffnesses along with larger energy absorptions in the bending process compared to the single steel sheet.
