“…[6] It has been well reported that the fiber-matrix interface plays a vital role in improving the various properties of FRPs. [7] Kevlar has a chemically inert and highly crystalline structure, which leads to a poor interface between its smooth surface and the matrix. [8] One of the proposed methods to create a good interface between a polymeric matrix and the Kevlar fibers is to disperse nanoparticles in the matrix system, which enhances the effectiveness of the fibers.…”

In this paper, the individual and synergistic effects of silanized-multiwalled carbon nanotubes (S-MWCNTs) and silanized-Titanium dioxide (S-TiO 2 ) nanoparticles on the drop-weight impact response of Kevlar fiber-reinforced epoxy (KE-EP) composites were evaluated. In the first step, the nanofillers were functionalized using an amino organosilane coupling agent (3-Aminopropyltrimetoxysilane [APTMS]). Next, multiscale composites were prepared by adding 0.3 wt% S-MWCNTs, 1 wt% S-TiO 2 , and 0.3 wt% S-MWCNTs + 1 wt% S-TiO 2 in the matrix.The samples were exposed to drop-weight impact at various impact energies of 15, 30, and 45 J. The findings demonstrated that the sample filled with 0.3 wt% S-MWCNTs + 1 wt% S-TiO 2 had the best impact performance, regardless of the initial impact energy. When compared to the neat KE-EP sample, the multiscale composite filled with 0.3 wt% S-MWCNTs + 1 wt% S-TiO 2 had greater peak force and absorbed energy by 23% and 18%, respectively under 45 J impact energy. Analysis of the fracture surfaces illustrated a good interfacial bonding between the Kevlar fibers and matrix for the multiscale composite having hybrid nanofillers.

“…11 Aramid fiber is widely used as a reinforcing agent in composites in the form of fiber bundles, continuous filaments, pulp, woven textile material, short fibers, powder, etc. [12][13][14][15] Therefore, to improve the interfacial connection, different methods of modifying the fiber surface are used, which traditionally favor either physical or chemical adhesion with the matrix. Therefore, a series of fiber surface treatment techniques have been developed: ultrasonic treatment, γ-ray irradiation, plasma treatment, etching, cryogenic treatment, and chemical grafting to improve interfacial adhesion strength.…”

The paper presents a study on composites based on 50:50 (PP:LLPE‐g‐MA) reinforced with 0.5, 1, and 2 wt% aramid fibers unmodified/modified with TiO2, processed by melt compounding. Micronic aramid fibers were acetone washed to remove impurities and treated with Ti(IV)isopropoxide precursor via sol–gel method, adding microcellulose for TiO2 particle dimension control. Composites were hot‐pressed into 4 mm‐thick plates for sampling and 0.5 mm‐thick sheets for thermoforming. All composites were successfully thermoformed, fibers‐based samples showing improved thermoforming ability without wrinkling. Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and Energy dispersive X‐ray spectroscopy (EDS) analysis confirmed the formation of TiO2 particles on the fiber surface. Optical microscopy, SEM and FTIR analysis exhibit the fibers' strong embedment into the matrix due to physical interlocking, generating surface defect reduction. Water absorption decreased from 0.195% (control) to 0.075 and 0% for 1 TiO2 and 2 TiO2 samples, due to material compactization. Contact angles increased from 95.18° (Control) to 108° (1 TiO2) and 112.89° (2 TiO2). The highest flexural strength and modulus were exhibited by 1 TiO2 sample that increased by 44.88% and 47.6% compared to the control sample, due to higher intrinsic rigidity of fibers and TiO2 modifying surface rugosity and phase interaction. The impact strength of the control sample improved by 139% compared to PP due to brittleness reduction, 1 TiO2 by 209% compared to PP, 29% compared to the control sample. The results and excellent thermoformability recommend the materials for encapsulation of electronic/expensive parts in automotive or drone applications, offering viable, facile, rapid, and cost‐effective solutions to easily replace damaged parts.Highlights Aramid fibers were successfully modified using isopropoxide precursor; Strong embedment of fibers in the polymer diminishes crack propagation/damage; Improved impact and bending properties and water contact angle; The composites showed a high ability to thermoform into complex shapes; Potential to replace non‐reusable materials as encapsulation solutions.
