Abstract Untreated jute‐fabric (JF) and triple‐super‐phosphate treated JF were incorporated in isotactic polypropylene (PP) to prepare sandwich composites. Untreated JF reinforced PP (UC) and treated JF reinforced PP composites (TC) were prepared using the compression molding technique at 180°C under a load of 5 tons. Both, TC and UC were irradiated by γ‐rays at various doses to produce γTC and γUC. The highest tensile‐strength ( TS ), flexural‐strength ( FS ) and Young's modulus ( E ) were observed for the composite loaded with 55 wt % JF and irradiated at a dose of 5.0 kGy and. The maximum increases in TS , FS , and E of γTC from UC are 17, 18, and 69%, whilst those of TC from UC are 12, 13, and 12%, respectively. Thermal degradation temperature of γTC and TC is found to increase significantly from that of UC, suggesting an improved thermal stability of the treated composites. All these findings are explained on the basis of fiber‐matrix interactions developed by the formation of physical and chemical bonds among JF and PP, as demonstrated by means of the Fourier transform infrared spectroscopy. © 2013 Wiley Periodicals, Inc.
