Mechanical properties and chemical reaction of 3-aminopropyltriethoxysilane of polypropylene, recycle acrylonitrile butadiene rubber and sugarcane bagasse composites

The mechanical and chemical properties of sugarcane bagasse (SCB) treated with 3-aminopropyltriethoxysilane (3-APS) filled polypropylene (PP)/recycled acrylonitrile butadiene rubber (NBRr) bio-composites were aim and investigated. The composites with different SCB loading from 5 wt.% to 30 wt.% were prepared using heated two-roll mill by melt mixing at temperature of 180°C. Tensile properties of composites which is tensile strength, Young Modulus and elongation at break were investigated. Increasing of treated SCB filler loading in composites have increased the Young modulus, however, decreased the tensile strength and elongation at break of the composites. The chemical properties and morphology of composites were investigated using Fourier transform infra-red analysis. These findings were supported by micrograph diagram from the morphological study. SCB filler treated with 3-APS has improved the adhesion and gave strong interfacial bonding between SCB filler and PP/NBRr matrices which results in good tensile strength of composites.
