Dynamic Mechanical Analysis on Jute Fiber Reinforced Polymer Composites for Patella Implant

Natural fibres possess convincing properties when reinforced in polymers. In this study, JFRPs viscoelastic behaviour at low and elevated temperatures were explored. The present work focuses on the fabrication of jute reinforced polyester based polymer composites with different fiber compositions. Untreated long Jute fibres and mat structured Jute fibres were used for preparing the specimens. The Dynamic Mechanical Analysis (DMA) test was carried out on selected developed Polymer Matrix Composites (PMC). Density of selected PMCs are nearly equal to the bone density. So, PMC specimens were considered to carry out thermal analysis using DMA. In particular, by dynamic mechanical analysis experiments, properties such as storage modulus, loss modulus, tanδ and glass transition temperature were determined. It was found that the storage modulus (E’) recorded above the glass transition temperature (Tg) varies with increase in temperature. Along with the previous research of material properties for possible bioimplantation, this Tg value is identified for possible implementation as patella bone implant. The loss modulus (E”) and damping peaks (Tan δ) values were found to be reduced with increasing matrix loading and temperature.
