“…Composite materials for ballistic protection are mostly based on fibers of high toughness and tensile strength, like aramid fabrics, impregnated with a thermoplastic or thermosetting polymer, or their combination [19,20,34,35], often a combination of phenolic resin with poly (vinyl butyral), PVB. In order to achieve additional reinforcement of ballistic composite systems new technologies are developed.…”

“…In the research conducted in VTI nanoparticles and nanotubes of tungsten disulfide were applied as a reinforcement of composites for personal ballistic protection based on aramid fabric and polymer matrix [19][20][21][22]. Laminated composites of improved mechanical properties were prepared using aramid fabric coated with phenolic resin, poly (vinyl butyral) and nanoparticles of IF-WS 2 , ultrasonically dispersed in ethanol, keeping the processing parameters (temperature, pressure and the duration of pressing) at defined values.…”

“…EDS analysis (energy dispersive X-ray spectrometer) and element mapping has showed good spatial distribution of IF-WS 2 . Optical microscope images and SEM/EDS analysis confirmed that aramid fabric is well impregnated with the system phenolic resin/PVB/IF-WS 2 [19][20][21][22]. The effect of adding WS 2 on thermo-rheological and elastic properties of the composites has been examined using Dynamic Mechanical Thermal Analysis (DMTA).…”

Currently, it is important to manufacture fiber‐reinforced epoxy matrix composites with high impact resistance besides their high strength and modulus values for industries such as automotive, aerospace, and aviation due to the brittle structure of epoxy. In this regard, we found the attractive results of the 0.5 wt% poly(vinyl butyral) (PVB)‐containing epoxy blend in terms of strength, Young's modulus, and impact resistance. These results substantially motivated us to manufacture fiber‐reinforced advanced epoxy/PVB matrix composites with 30–60 vol% carbon‐aramid fiber ratios. Flexural (three‐point bending) and tensile tests were performed to obtain strength and modulus values by measuring the force required to break the fiber‐reinforced composite specimens and elongation at break points. Interlaminar shear strength tests were performed by the short beam bending method by measuring the resistance of the composite to delamination. The Charpy impact test was used to measure the energy absorbed during crack formation and fracture propagation. The composites with PVB were generally superior to those without PVB (EPCs). Two types of findings were observed. First, PVB increased the tensile and flexural strength values substantially for the 30 and 40 vol% ratios, but the modulus values slightly decreased. Second, PVB also substantially increased the modulus values for the 50 vol% ratio besides the strength values. It was thought that this result could be attributed to the increase in the compatibility of the fiber/matrix for the 50 vol% ratio. These decreases for EPCs could be derived from the micro‐cracks and weaker interface between fiber and matrix.
