Nanocomposite materials are obtained as a dispersion in a nanometer dimension within one second phase and are defined as at least two phase material groups. Carbon Nanotube is an allotropic of carbon element [1]. In other words, they are obtained by cylindrical wrapping of plates in the form of honey pellets. In shapely carbon nanotube structures, atoms are connected to each other by sp2 (like graphite), atoms form hexagonal geometry, and each atom has only three neighbours. Carbon nanotubes have high resistance to impacts such as compression, bending, twisting due to hole structures and high length / diameter ratios [2]. There are single-layer (single-walled) or multi-layer (multi-walled) carbon nanotubes. Previous scientific investigations have demonstrated that multi- walled CNTs (MWCNTs) have higher resistance to chemicals than single-walled CNTs (SWCNTs). Carbon nanotubes are one hundred times stronger than steel, and weight is one sixth. Steel is harder at the same time, but as flexible as plastic. Therefore, it is the most robust material known to have high corrosion resistance. [3] Because of these properties, CNTs have been used. In addition, if we look at the structure and properties of Epoxy; the low molecular weight of liquid immature epoxy resins gives them superior molecular mobility during processing. High strength thermoset polymers such as epoxy are added to glass fiber to increase mechanical strength and thermal stability [4]. This important feature allows the liquid epoxy resins to be quickly wetted to the surface. Fiber reinforced materials generally have more resistant structure than unreinforced materials. As the glass fiber ratio increases, the strength of the material increases [5]. Adding more fibers can increase tensile and impact strength, while layer delamination occurs under tensile, compressive and shear loading [4]. There are some studies on the improvement of interfacial and mechanical properties of thermoset composites by incorporating CNT into composites by fiber coating. From here it is aimed to increase the compression after impact properties of the new nanocomposites, which we will produce by improving the interface between resin and fiber, thus reaching new areas of use.

Due to fast fabrication process, low manufacturing cost and mass production properties of thermoplastics, thermoplastic composites are being used in various industries such as automotive, aerospace, wind turbines etc. On the other hand thermoplastic composites have some disadvantages against thermoset such as thermoplastic resin have very high viscosity. In order to overcome the high viscosity issues, some of the thermoplastics polymers were produced in the form of fibers. Commingled fibers content the mixing of matrix fiber and reinforcing fiber. Biaxial weft-knitted fabrics include weft and warp yarn layers. Commingled fibers can be used as weft and warp yarns in biaxial weft-knitted fabrics. It is possible to fabricate thermoplastic composites by using biaxial weft- knitted fabrics. Carbon Nanotube is an allotropic of carbon element [1].

In addition, if we look at the structure and properties of Epoxy; the low molecular weight of liquid immature epoxy resins gives them superior molecular mobility during processing. High strength thermoset polymers such as epoxy are added to glass fiber to increase mechanical strength and thermal stability. The addition of nanoparticles lead to increases in inter fibre fracture strength of up to 16% [4].This important feature allows the liquid epoxy resins to be quickly wetted to the surface. Fiber reinforced materials generally have more resistant structure than unreinforced materials. As the glass fiber ratio increases, the strength of the material increases. The addition of MWCNTs not only increases the tensile strength of the epoxy matrix but also increases fracture toughness.[5] Furthermore, it has been demonstrated that the inner layers of an MWCNT can be effectively deformed only through the direct application of tensile or shear forces, not through van der Waals interactions[6]. There are some studies on the improvement of interfacial and mechanical properties of thermoset composites by incorporating CNT into composites by fiber coating. From here it is aimed to increase the bending properties of the new nanocomposite which we will produce by improving the bonding of the resin / fiber interface, thus reaching new areas of use.
