“…Nonwoven-they are often referred to as mats, can be manufactured in a large variety of formulations and spatial layouts and provide high strain and permeability; their most relevant feature is their ability to resist damage by local lengthening, despite their low tensile strength; 3. Knitted-whether warp-knitted or weft-knitted, these fabrics have tridimensional architectures with multiaxial, in-plane and out-of-plane reinforcements; they represent only 5% of the geotextiles currently used, but the demand for knitted geotextiles is rapidly increasing due to their particular mechanical properties [31,32]. Aside from these types of geotextiles, in practice there are other materials considered as geotextile-related products, such as geomesh, geonets, geocells, geogrids and geocomposites, which are used individually or in combination with others in order to enhance their action by working in synergy or to obtain a multitask layer General requirements that operative geotextiles need to meet in terms of properties are as follows [3,16]: 4.…”

Geotextiles, a group of high-performance materials, have grown during the last decades into needful auxiliaries when it comes to infrastructure, soil, construction, agriculture and environmental applications. Although geotextiles made of synthetic fibers (geosynthetics) are considered a modern achievement, the basic concept dates back to ancient times when textiles consisting of locally available natural fibers were employed to increase the stability of roads and soils. In recent decades, considering the growing interest in environmental protection and sustainable development based on using renewable resources and the recovery and recycling of waste of various origins, the use of natural fibers-based geotextiles is a viable alternative, despite their limited-life service owing to their biodegradability. In addition to this feature, their low cost, good mechanical properties and large-scale accessibility recommend them for geo-engineering applications, environmental sensitive applications in geotechnical engineering, such as land improvements and soil erosion control. This paper focuses on geotextiles as a versatile tool in environmental applications given their high theoretic and practical relevance as substantiated by recent literature reports. Natural and synthetic geotextiles are presented herein, as well as their features that recommend them for geo-engineering. Insights on the main types of applications of geotextiles are also included, along with a wide variety of materials employed to perform specific functions.

“…In addition to mechanical properties, an enhancement in preferable characteristics like barrier, thermal, flame retardancy and electrical properties is achieved. [10][11][12][13][14] In this regard, graphene is a new two-dimensional (2D) material, which has fascinated remarkable attention due to its superior physicochemical properties like high surface area (2600 m 2 /g), stiffness (0.7 TPa), strong mechanical strength (130 GPa), good biocompatibility, high Young's modulus ($1 TPa), excellent thermal conductivity ($5000 W/mK), and unique electrical conductivity ($7200 S/m). [15][16][17][18] Moreover, graphene nanolayers are the centerpiece of polymer composites' researchers as a reinforcing agent because of its superior mechanical properties.…”

In this study, the effects of graphene network formation on stress–strain behavior and different mechanical properties in PP/EPDM nanocomposites were investigated. TEM observation clarified that up to the optimum content of nanoparticles, the efficient networks of graphene formed which heightened the nanocomposites tolerance against different mechanical loads. The efficiency of graphene networks in arresting crack along with the mechanisms through which they dissipate energy were extensively examined. SEM observations from the fracture surface of impact test indicated that as a result of these networks, the cracks perpendicular to the load directions were formed which efficiently assisted the nanocomposite in dissipating energy and/or hindering further development of cracks and the premature failure in PP/EPDM samples. The stress–strain behavior of resultant nanocomposites was also studied by Arruda–Boyce hyperelastic model which can predict the behavior of nanocomposites with a high degree of accuracy that is rooted in the increased interaction between graphene and polymer matrix by graphene network formation. Exceeding the optimum content, the agglomerations form and results in deviation of experimental results with the model predictions. The findings of this model also substantiated the efficiency of graphene networks in developing a load‐resistant the microstructure of PP/EPDM nanocomposites.
