Abstract
Implementation of “green laws” in several countries hasgeneratedrenewed research interest in natural fiber reinforced composites in different industrial sectors such as automotive, construction, building and electrical. In this study, we have investigated the effect of chemical treatment of hemp fiber on thermal and mechanical properties of hemp fiber composites with recycled high density polyethylene matrix. The chemical composition effect on thesurface modification wasanalyzed by means ofFourier transform infrared spectroscopy (FTIR) and the thermal stability of composites properties were studied bythermo gravimetric analysis (TGA). The mechanical properties of the composites were testedin accordance to ASTM D790 with fiber volume fractions in the range of 20-40%. The results showed that the chemical treatment of hemp fiber improved the thermal stability of the fiber. The maximum flexural strength of hemp fiber composites of 44.6MPa was observed with the composite containing 40% fiber volume fraction.
