Abstract
The thermal and dynamic mechanical properties of jute fibre reinforced high density polyethylene (HDPE)/ ethylene-propylene-diene terpolymer (EPDM) composites were studied. The fibre loading was varied between 10 and 30 wt%, and at each fibre loading, four compatibiliser doses were used. Dynamic parameters (storage flexural modulus (E'), loss flexural modulus (E”), loss factor or damping efficiency (tanδ) were determined in a resonance frequency mode. The storage modulus increased with increasing fibre content and a further increase was observed with the addition of compatibiliser. The tanδ was decreased by an increase in fibre content because of the restricted mobility of the polymer chains caused by the fibres. A marginal shifting of the transition was observed with an increase in the compatibiliser dose at constant e fibre loading. A low concentration of fibre increased the crystallinity of HDPE because it acted as a nucleating agent.
