“…This indicates that the matrix structure has been weaker than the nanostructures on the fiber surface, which further suggests that the nanostructures are very strongly attached to the fiber surface creating a strong and robust network of contact points. The results, achieved in this study with the microwave assisted surface treatment, are comparable with results of other studies [15], [14], [19] where hierarchical structures are induced to the fiber surface to increase adhesion. In further studies it would be interesting to compare the results of this surface treatment to RFL treated aramid fibers.…”

“…However, RFL is typically applied only to cord or woven fibers, which have different surface structure to loose fiber bundles, which influences the results. Here the increase in adhesion was achieved with nano-deposits protruding from the fiber surface, mechanical interlocking is the main adhesion mechanism, as also Hazarika et al stated in their study [19]. Mechanical interlocking is universal to all material types, which suggests that an increase in adhesion may also be achieved with other matrix materials as well.…”

“…Also in a quite recent study [18] microwaves were used to manufacture carbon nanotubes in the presence of graphite and ferrocene bis(η5-cyclopentadienyl)iron. This method was successfully used to treat woven aramid fibers in a study by Hazarika et al [19]. They were able to grow iron particle decorated carbon nanotubes to activated woven Kevlar fibers.…”

“…When the saturation point of the nanoparticles is reached, the growth of carbon nanotubes begins. With their method Hazarika et al were able to increase the in-plane shear strength of aramid-polyester resin composites by ~81% [19]. However, they did not investigate the effect of the surface treatment to the tensile strength of the individual fiber filaments.…”

At the moment several commercial surface treatments are used to increase adhesion between aramid fiber and matrix material in composite structures but each of these have some limitations. The aim of this study is to address some of these limitations by developing a surface treatment method for aramid fibers that would not affect mechanical properties of the fibers negatively, could be used with any matrix material and that could withstand handling of the fibers and ageing. The method used is microwave assisted surface treatment that uses microwave radiation together with dry reactive chemicals to create hierarchical structures to the fiber surface and so makes it possible to control the adhesion properties of the fibers. SEM imaging, fiber tensile tests and modified bundle pull-out test were used to investigate the outcome of the surface treatment and measure adhesion between aramid fiber bundles and rubber. SEM imaging revealed that nanoscale deposits are formed on to the fiber surface which enable mechanical interlocking between the fiber and the matrix material. Fiber tensile tests showed that the surface treatment does not influence tensile properties of the fiber negatively. Results from the bundle pull-out tests confirmed that this kind of method can lead up to 259% improvement in adhesion when compared to untreated aramid fibers in rubber matrix.

We investigated the effect of modified aluminosilicates, including bentonite from Armenia (BA) modified with quaternary ammonium salts (BAQAS) and phosphonium salts (BAQPS), on the mechanical properties and morphology of Kevlar/epoxy composites. The Kevlar/epoxy composites containing 1.0 or 3.0 wt.% modified bentonites were fabricated using the hand lay-up technique. The mechanical properties, including the tensile, flexural, and in-plane shear strength, were tested. Based on the obtained results, we found that the mechanical properties increased with modified bentonite loading. The best results were obtained for composites containing 3 wt.% BAQAS, as most of the mechanical properties were significantly improved (tensile strength 302.9 MPa (+30%), Young’s modulus 16.3 GPa (+17%), flexural modulus 23.4 GPa (+12.5%), in-plane shear strength 22.8 MPa (+24.5%), and in-plane shear modulus 677.2 MPa (+42%)). The obtained improvements in the mechanical properties are attributed to the uniform dispersion of the filler, which was confirmed by the highest increase in the intergallery spacing, from 28.3 Å for BAQAS to 45.1 Å for the composite with 3 wt.% BAQAS. Scanning electron microscopy (SEM) analysis of the brittle fracture surface indicated that the addition of modified bentonite to the epoxy matrix changed the morphology of the Kevlar/epoxy/organoclay composites and improved the fiber–matrix interfacial adhesion.
