Abstract

This study is to investigate the wear behaviour of several bagasse-polymer-cement composites with different ratios of styrene butadiene latex (SBR) content; 3%, 6% and 12%. The main precursor; sugar cane were chopped into 5mm in length and randomly dispersed within the matrices bagasse-polymercement composites with 6% of SBR content was found to gain the highest value of hardness. They were selected to irradiate to dose of 10kGy and 20kGy of electron beam irradiations, in order to modify the microstructure of bagasse-cement composites. It was noted that tensile strength was greatly improved with greater irradiations dose. The sliding wear test was conducted in a dry sliding condition against hardened carbon steel of +60 HRC of 1 m/s. Under a pin-on disk configuration, the tests were carried out at 10N and 50N of load range in a room temperature (~25 √ęC). It was found that composites with 6% of SBR content which exposed at 20kGy irradiation showed the best wear resistance with 463-5.2!10^(- 4) Mm"/Nm, at both low and high load. Observation by the scanning electron microscopy on the microstructure of the irradiated composites indicated that the voids within the matrices were greatly reduced, which therefore increase the mechanical properties, as a whole, than there of unirradiated areas. Finally, the predominant wear mechanism on this case were mostly plastic deformation, ploughing, fragmentation of were debris on the matrix, excessive determination of fibre surface followed by delimitation and fiber removal.
