“…Silanization of the GF surface usually proceeds via GF treatment in the solution of silane; the solvent may be either organic, such as ethanol [ 17 , 18 , 19 , 20 , 21 , 22 , 23 ], methanol [ 24 ], toluene [ 25 ], cyclogexane [ 26 ] or tetrohydrofuran [ 27 ] or water-based [ 28 , 29 , 30 , 31 ]. Silanized GF are widely used for polymer reinforcing.…”

“…Silanized GF are widely used for polymer reinforcing. Most of all, epoxy resin is used as a matrix polymer in such composites [ 17 , 18 , 19 , 20 , 23 , 25 , 29 , 30 ]. The use of another matrix polymer, such as polylactide acid (PDA) [ 24 , 32 , 33 ], polypropylene [ 22 , 31 ], polypropylene oxide [ 28 ], polyoxymethylene [ 22 ] and polyamide 6.6 [ 21 ] were reported also.…”

Filler in such composites may represent GF in a short [ 20 , 22 , 24 , 27 , 29 , 31 , 32 , 33 ], unidirectional [ 23 , 25 ] or fabric [ 17 , 18 , 19 , 21 , 28 , 30 ] state. Silane treatment of GF allows for an increase in the composite density [ 18 , 29 ], i.e., to decrease the defectivity of the macrostructure.…”

“…Silane treatment of GF allows for an increase in the composite density [ 18 , 29 ], i.e., to decrease the defectivity of the macrostructure. It was observed that silane treatment of GF results in an increase in tensile [ 18 , 22 , 24 ] and flexural [ 19 , 20 , 30 ] strength, elastic moduli [ 18 , 19 , 20 , 24 , 30 ] and elongation at the break [ 22 ] of composite materials. In a comparative study on the effectiveness of GF in reinforcing polylactide (PLA) using silane coupling agents (GF-S) and graphene oxide (GF-GO) as surface modifiers, Jing et al [ 32 ] found that the use of GF-S significantly increases the mechanical strength and maintains the relatively good toughness of composites.…”

The chemical structure of the surface of glass fibers, including silanized fibers, was studied. Highly efficient heat-resistant composites were obtained by impregnating silanized glass fiber with a polysulfone solution, and the effect of modification of the surface of glass fibers on the physical, mechanical and thermophysical properties of the composite materials was studied. As a result of the study, it was found that the fiber-to-polymer ratio of 70/30 wt.% showed the best mechanical properties for composites reinforced with pre-heat-treated and silanized glass fibers. It has been established that the chemical treatment of the glass fibers with silanes makes it possible to increase the mechanical properties by 1.5 times compared to composites reinforced with initial fibers. It was found that the use of silane coupling agents made it possible to increase the thermal stability of the composites. Mechanisms that improve the interfacial interaction between the glass fibers and the polymer matrix have been identified. It has been shown that an increase in adhesion occurs both due to the uniform distribution of the polymer on the surface of the glass fibers and due to the improved wettability of the fibers by the polymer. An interpenetrating network was formed in the interfacial region, providing a chemical bond between the functional groups on the surface of the glass fiber and the polymer matrix, which was formed as a result of treating the glass fiber surface with silanes, It has been shown that when treated with aminopropyltriethoxysilane, significant functional unprotonated amino groups NH+/NH2+ are formed on the surface of the fibers; such free amino groups, oriented in the direction from the fiber surface, form strong bonds with the matrix polymer. Based on experimental data, the chemical structure of the polymer/glass fiber interface was identified.

“…According to the results of the study, the load carrying capacity of the filaments under tension decreased by 40% after 180 minutes of oxidation, and the best performance in terms of adhesive performance was obtained with 90 minutes of oxidation with nitric acid. In a study by Lou et al [8], three different methods (ultrasonic surface cleaning, nitric acid oxidation and combination of ultrasonic and nitric acid oxidation) were applied to treat the surface of carbon filaments added to epoxy. In terms of the performance of the composite, they stated that the most suitable method among these applied methods is the method in which ultrasonic and nitric acid oxidation are applied together.…”

In the present study, chemically surface-treated nanoparticles and nanofibers were added to the adhesive to improve the performance of the two-component structural adhesive. In the study, DP460 structural adhesive was used as adhesive, functionalized Multi Walled Carbon Nanotubes (MWCNT-COOH) with COOH and carbon fiber (CF) chemically surface treated with HNO3 solution were used as nanostructures. In the experimental study, eight different parameters were investigated as the nanostructure was (i) undoped, (ii) 1 wt% MWCNT-COOH added, (iii) 1wt%. untreated CF added, (iv) 0.5 wt% chemically treated CF added, (v) 1 wt% chemically treated CF added, (vi) 2 wt% chemically treated CF added, (vii) 0.5 wt% MWCNT-COOH and 0.5 wt% chemically treated CF added, and (viii) 1 wt% MWCNT-COOH and 1wt% chemically treated CF added. According to the results of the study, adding nanoparticles to the adhesive increases the performance of the adhesive by about 12%, while adding nanofibers increases the performance of the adhesive by about 18%. In addition, increasing the inertness and wettability of nanofibers by chemical treatment, as well as the use of nanoparticles and fibers together, significantly increases the performance of the adhesive. In addition, the obtained results were supported by fourier transform infrared spectroscopy (FT-IR) analysis and scanning electron microscopic (SEM) analysis.
