Abstract:
This paper reports the creep behavior of alkali treated jute/green epoxy composites incorporated with
various loadings (1, 5 and 10 wt%) of chemically treated pulverized jute fibers (PJF) at different envi-
ronment temperatures. Composites were prepared by hand layup method and compression molding
technique. The creep and dynamic mechanical tests were performed in three-point bending mode by
dynamic mechanical analyzer (DMA). The incorporation of PJF is found to significantly improve the creep
resistance and strain rate of composites. Three creep models i.e. Burger’s model, Findley’s power law
model and a simpler two-parameter power law model were used to model the creep behavior in this
study. The time temperature superposition principle (TTSP) was applied to predict the long-term creep
performance. The Findley’s power law model was found to be satisfactory in predicting the long-term
creep behavior. Dynamic mechanical thermal analysis (DMTA) results revealed the increase in storage
modulus, glass transition temperature and reduction in the tangent delta peak height of composites with
higher loading of PJF.
