This chapter discusses the emerging materials in polymer reinforcement, covering nanocomposites. Their properties, importance in the world's advancement, applications, and limitations were discussed. The increase in the application of these new materials has accelerated the research and production of new concept materials and implementation of materials with multi structures. Composite materials are made using a variety of processes, each of which is appropriate for a particular material, because each material has various physical qualities. The effectiveness of the manufacturing procedure is determined by the way the matrix and reinforcement are joined and the way the phases react with each other. As a result, manufacturing procedures are determined by the material chosen. Research on emerging materials in polymer reinforcement is gaining a lot of research interest due to their excellent properties and because it holds a lot of potential for enabling new uses and applications in industries. They broaden the range of applications for a specific polymer in the most basic way. New studies will focus on ways to improve the already existing materials and ways to create new materials according to industrial demands.
3D Printed Flexible and Stretchable Electronics
Published in Muhammad Mustafa Hussain, Nazek El-Atab, Handbook of Flexible and Stretchable Electronics, 2019
Finally, nanomaterials such as carbon nanotube, graphene, graphite, and several kinds of ceramics and metals often exhibit unparalleled advantages in terms of mechanical, electrical, and thermal properties [29]. For this reason, recently, several different approaches have been made in order to introduce nanomaterials as reinforcement for polymers. Here, homogeneous dispersion of the nanoparticles into the polymers is essential in order to achieve the desired characteristics of the composite. However, agglomeration of nanoparticles can usually damage the polymeric composite and cause non-uniformity across the materials. For this reason, chemical treatment of the base materials is usually required before embedding nanoparticles.

Apart from polymer blending, the modifications of thermoplastic SPS were also carried out by incorporating reinforcement into the material. To preserve the environmentally friendly characteristics of the thermoplastic SPS, natural reinforcement such as natural fibers has been used to enhance the properties of this biopolymer.

Similarly, Straw was also used as reinforcement in ancient structures (Stefanidou et al., 2012) and many research works investigated the effect of incorporation of straw fibers in construction (Snoeck & De Belie, 2015). As it is reported (Hejazi et al., 2012), the incorporation of straw fibers enhances the performance of composites with clay matrix. The reinforcement allows an improvement of mechanical properties. Also, it provides a reduction of shrinkage and curing time (Bouhicha et al., 2005). Moreover, a mixture of straw and cement could contribute to a construction material production of low-cost and low air pollution providing both economic and environmental benefits (Mansour et al., 2007).

Composite materials are widely used in aerospace, marine, automotive, and other industries due to desired mechanical properties such as high strength-to-weight ratio. However, analysis of the mechanical behavior of composite materials is more complex than other materials because of the anisotropic nature of the composites [1], [2]. The composite materials mainly have two components called reinforcement and matrix. The most common reinforcement types are fibers. One of the newcomers used for the fabrication of the advanced composite materials is basalt fiber. Basalt is a natural inert material produced naturally from the volcanic rocks. Composites reinforced with basalt fibers have prominent properties over the other composites. Compared to carbon and aramid fiber, basalt fiber has the features of wider application temperature range (−269°C to +650°C), higher oxidation resistance, higher radiation resistance, higher compression strength, and higher shear strength. Moreover, basalt fiber has 17.5% better elastic modulus than glass fiber, is considered as “green” recyclable, respirable and safer material even in the factory. No UV treatments are needed for the basalt fiber. It does not harbor mold, mildew or bacteria and has ten times better electrical insulator than glass fiber with high temperature strength. It will not ignite easily with the right resins. Basalt composites with better impact strength do not shatter like carbon fibers and are great at blast mitigation [3], [4]. They also protect from nuclear radiation and does not conduct electricity or interfere with RF signals or MRI waves. Although basalt fibers have good mechanical performance, in particular at high temperature, its possible applications has not been investigated completely yet. Moreover, new basalt fiber composite applications could be widely used in near future due to the potential low cost of this material [5].

Some of the inherent advantages of the tile vaulting technique (economy, efficiency, and expressiveness) can be enhanced by combining it with reinforcement and/or concrete. Using tile vaults as permanent formwork for concrete reduces time and labor, and therefore costs. The addition of reinforcement can reduce thickness, and therefore weight, material and costs. Furthermore, it allows the construction in seismic areas and permits building forms beyond the realm of compression only.
