High strength, high toughness, and low weight make fiber-reinforced composite materials important as an alternative to traditional materials. Due to their application in different fields, such as construction, aviation, marine, automotive technologies and biomedicine, their production has increased leading to the increasement of composite wastes. New technologies for managing fiber-reinforced composite wastes have been developed to solve the issue of end-of-life of these materials.

Fiber reinforced composites are used widely for their high strength and low weight advantages in various aerospace and automotive applications. While their use may be sought after, modeling of these material requires increasing fidelity at the lower scales to capture accurate material behavior under loading. The first steps in creating statistically equivalent models to real life cases is developing a method of rapid evaluation and artificial microstructure generation. The outlined work is capable of tracking microscale fiber positions and determining regions of localized volume fraction extrema (high and low end). Groupings of high and low volume fraction regions are called clusters and their geometry is used to characterize the microstructure. These cluster features can be evaluated for both artificial models and actual scans, allowing correlation to be established which can ultimately be used to regenerate statistically equivalent models. The results of this work show that if one feature is to be correlated, a model can be generated which matches almost exactly. But once more features are equally taken into account, the regeneration loses accuracy.

Sereni stem fiber, due to low weight and high tensile strength was selected as backbone for graft copolymerization with binary vinyl monomeric mixture to explore its effect on percentage grafting, properties and the behavior of the modified fiber. The graft co-polymers were reinforced in a phenoplast matrix to form fiber reinforced composites and were characterized by XRD, TGA, DTA, SEM and FTIR techniques. Moisture absorbance, chemical resistance in acid and base and assessment of flexural strength, young's modulus, stress at the limit of proportionality, and hardness of the composite were studied in comparison to the phenoplast.

Composite Bridges

Composite materials are often used in the construction industry nowadays. Including such industries as construction of bridges – unique structures. Today it is possible to produce from FRP not only separate bridge parts and single structural elements, but also entire span structures and one-piece composite bridges made as a monoblock element. The architecture of contemporary footbridges built with the use of fiber reinforced composite plastics in recent decades is being studied and analyzed in the article. The case-study examines the history of plastic composites as structural materials and the trends and evolution of the design of plastic products. The paper proposes a classification of modern pedestrian bridges made of fiber reinforced composites (based on a combination of innovation in the use of materials and in the design). The following three classes are distinguished: composite materials + traditional design; composite and traditional materials + hybrid design; composite materials + new design. The most recent examples of objects belonging to each of the three groups identified in the classification were reviewed and analyzed in course of the study (including contemporary Russian examples of composite pedestrian bridges). Particular attention is paid to the most advanced technologies, such as 3D-printing of composite bridges, as well as a number of other contemporary experimental production methods. The experience of scientists and manufacturers from Germany, Spain, Great Britain, China and other regions of the world has been studied. Further research and application of modern fiber-reinforced composites in combination with the latest production technologies of 3D-printing and computer parametric design can contribute to the development of modern bridge construction, which would be helpful for expanding the typology of structures and improving the design of new structures.

Composites have been found to be the most promising and discerning material available in this century. Presently, composites reinforced with fibers of synthetic or natural materials are gaining more importance as demands for lightweight materials with high strength for specific applications are growing in the market. Fiber-reinforced polymer composite offers not only high strength to weight ratio, but also reveals exceptional properties such as high durability; stiffness; damping property; flexural strength; and resistance to corrosion, wear, impact, and fire. These wide ranges of diverse features have led composite materials to find applications in mechanical, construction, aerospace, automobile, biomedical, marine, and many other manufacturing industries. Performance of composite materials predominantly depends on their constituent elements and manufacturing techniques, therefore, functional properties of various fibers available worldwide, their classifications, and the manufacturing techniques used to fabricate the composite materials need to be studied in order to figure out the optimized characteristic of the material for the desired application. An overview of a diverse range of fibers, their properties, functionality, classification, and various fiber composite manufacturing techniques is presented to discover the optimized fiber-reinforced composite material for significant applications. Their exceptional performance in the numerous fields of applications have made fiber-reinforced composite materials a promising alternative over solitary metals or alloys.
