Abstract
The dynamic behaviour of fiber reinforced composites plays a significant role on the performance of the laminated composite materials. In the present study the dynamic characteristics of cellulose Glass Epoxy Composites (CGEC) and Cellulose Kevlar epoxy composites (CKEC) were investigated and compared with pristine glass epoxy (GE) and Kevlar Epoxy (KE) composites using Dynamic Mechanical Analyzer (DMA). Cellulose particles were liquefied in organic solvents such as Acetone, Dimethylformamide (DMF), Ethanol and Sodium Hydroxide (NaOH) to inspect the settling time and it was found that cellulose particles settled in short interval of time in solvents and hence NaOH was used to make solution as better dispersion with high settling time was observed with NaOH. The Glass and Carbon plies were coated with Cellulose using semi automated coating technique. The DMA test was conducted in accordance with ASTM 1867-13. The tests results revealed that initially all the samples exhibited high storage modulus but there was a small drop in storage modulus in the temperature range of 50-70˚C and considerable drop in storage modulus was observed in the temperature range of 70-90˚C and also it was found that composite laminates changed in state from solid to elastic beyond glass transition temperature (Tg)
