my.unimap-355572014-06-16T03:57:37Z Hybrid-filler filled polypropylene/ (natural rubber) composites: effects of natural weathering on mechanical and thermal properties and morphology Hakimah, Osman, Dr. Mariatti, Jaafar, Assoc. Prof. Dr. Hanafi, Ismail. Prof. hakimah@unimap.edu.my mariatti@eng.usm.my hanafi@eng.usm.my Recycled newspaper (RNP)/ carbon black (CB) Recycled newspaper (RNP) silica hybrid Tensile properties Composites Link to publisher's homepage at http://onlinelibrary.wiley.com/ Comparison was made between the properties of recycled newspaper (RNP)/carbon black (CB) and recycled newspaper (RNP)/silica hybrid filled polypropylene (PP)/natural rubber (NR) composites. The properties studied were mechanical, thermal, and morphological. These composites were also subjected to natural weathering, i.e., the tropical climate in Penang, Malaysia, for 6 months. The incorporation of CB and silica at all weight ratios of RNP/CB and RNP/silica hybrid gave increases in tensile strength, elongation at break (EB), Young's modulus, melting temperature (Tm), heat of fusion of composites (ΔHf(com)), crystallinity of composites (Xcom), and the crystallinity of PP (XPP). As expected, the tensile properties (except for Young's modulus), Tm, ΔHf(com), Xcom, and XPP of the composites exhibited lower values after weathering than before weathering. The extent of chemical degradation was studied by Fourier transform infrared spectroscopy, and the results showed the formation of several functional groups, i.e., hydroxyl, hydroperoxide, vinyl, carboxylic acid, and ketone. At the same filler weight ratio, the composites filled with RNP/CB hybrid showed higher values of tensile strength and EBbut lower values of Young's modulus, ΔHf(com), XPP, and XPP, as compared to those with the RNP/silica hybrid under weathering conditions. The good retention in tensile properties indicated that the replacement of RNP by CB and silica improved the weatherability performance of the PP/NR composites. 2014-06-16T03:57:37Z 2014-06-16T03:57:37Z 2008 Article Journal of Vinyl and Additive Technology, vol.14(3), 2008, pages 142–151 1083-5601 http://onlinelibrary.wiley.com/doi/10.1002/vnl.20156/abstract http://dspace.unimap.edu.my:80/dspace/handle/123456789/35557 10.1002/vnl.20156 en Wiley |
