The current work aims to study the mechanical properties of polypropylene /polyethylene blend (PP/PE) reinforced with treated sawdust composites. Benzoyl bromide aqueous solution and sodium bromide (NaBr) were used to treat the sawdust for 24 hr. Different weight ratios of sawdust (0,10,20,30 and 40) wt.%. were added to (PP/PE) blend and the specimens were extruded under 240oC to prepare the composite samples as well as the (PP/PE) blend. Infrared spectroscopy (FTIR) was used to study the structural properties of treated and untreated sawdust, as well as study the structure of (PP/PE) blend and its composites reinforced with sawdust. Flexural and impact strengths were studied. Thermal analysis via DSC device was also studied. Results showed that increasing the treated sawdust ratios from 0 to 40% wt. ed to increase in the values of impact strength, flexural strength and melting temperature of composite samples. Impact strength increased from 3kJ/cm2 for (PP/PE) unreinforced blend to 17 kJ/cm2 with 40%wt. of sawdust. Flexural strength increased from 8.9MPa for the unreinforced blend to 20 MPa of blend with 40 wt.% of sawdust. [ABSTRACT FROM AUTHOR] |
