Impact properties of Kolon/PVB fabrics reinforced with rice-husk silica particles

Abstract

This study presents the impact properties of the new form of hybrid thermoplastic composites. The Kolon fabrics were impregnated with the 10 wt% poly (vinyl butyral) (PVB)/ethanol solution with the addition of silica (SiO2) particles originating from rice husk or layered double hydroxide modified silica particles (FeAl-LDH@SiO2) as reinforcement. All the composites consisted of one layer of the impregnated fabric where the silica particles concentrations were 0.5 wt% and 1.0 wt% regarding PVB. The impact properties of the composite samples were analyzed by the controlled energy puncture impact tester. The structures of the composite samples were determined by the attenuated total reflection Fourier-transform infrared spectroscopy (ATR-FTIR) and field emission scanning electron microscopy (FE-SEM). The results showed that the Kolon/PVB/1 wt% FeAl-LDH@SiO2 sample yielded the maximum impact force.
