The thermal behavior of hemp-poly lactic acid composites with both untreated and chemically surface modified hemp fiber was characterized by means of activation energy of thermal degradation. Three chemical surface modification employed were; alkali, silane and acetic anhydride. Model-free isoconversion Flynn–Wall–Ozawa method was chosen to evaluate the activation energy of composites. The results...
This study investigates the effect of silane and NaOH treatments of hemp fiber on the thermal and thermo-mechanical properties of hemp-high density polyethylene composites. The results indicated that thermal stability of composites decreased with increase in fiber loading and treated composites had higher thermal stability in comparison to untreated hemp composites. Dynamic mechanical analysis revealed...
