| Popis: | The physical and mechanical properties of the six samples of polyurethane/p-aramid multiaxial fabric forms (Kolon fabrics) were analyzed by high speed impact tester. The samples were impregnated with 10 wt.% poly (vinyl butyral) (PVB)/ethanol solution and modified with γ-aminopropyltriethoxysilane (AMEO silane)/ethanol solution. Unmodified silica (SiO2) nanoparticles, tungsten disulfide (WS2) nanoparticles and multiwalled carbon nanotubes (MWCNT) were used as reinforcement for multiaxial Kolon fabrics. The SiO2/PVB mass fraction was 10 wt.%, while the WS2/PVB and MWCNT/PVB mass fractions were the same - 1 wt.%. The results revealed the increase of the maximal impact force and the total energy absorbed for all the samples compared to the unmodified Kolon fabric sample and the application possibilities of these materials for the antiballistic protection. |
