Description:
In this present work, the nano filled (Multi walled carbon nano tube) glass and sisal fiber reinforced hybrid composites were fabricated with varying the wt. % of MWCNT’s by 0%, 0.5% and 1% respectively. Compression molding technique is used to fabricate the composites and are subjected to dynamic analysis over a range of temperature (30-190 °C) at the frequency rate of 5Hz. The effect of temperature and nano filler on storage modulus (E′) loss modulus (E ″) and damping efficiency (tan δ) are determinedby using dynamic mechanical analyser (DMA). The shear and loss modulus obtained maximum values for 0.5wt.% MWCNT composites. Damping value is higher for 1wt.% MWCNT incorporated composites. By using ultrasonic probe sonicator, nano fillers are mixed in to the epoxy resin to prepare a modified resin. The dynamic properties are evaluated as per as ASTM standards.
