Dynamic Analysis of OMMT Nanoparticle Reinforced Polyester Resin GFR-PS Foam Sandwich Laminates

Objectives: To study the effect of modified (OMMT) nanoclay polyester resin on dynamic properties of Glass Fiber Reinforced (GFR)- Polystyrene Foam (PS) sandwich laminates experimentally. Methods/Analysis: The GFR– PS foam sandwich laminates are fabricated by hand lay-up process. Free vibration test has been conducted to evaluate dynamic properties of glass laminate and sandwich laminates. The morphological picture of the nanoclay dispersion in the polymer fracture samples has been investigated by using Scanning Electron Microscopy (SEM). Findings: The dynamic properties of the nano polyester sandwich have been significantly improved at 4% of nanoclay loading. Application/Improvement: From the results it is observed that, the effect of nano particle in fabricated composite significantly increases the dynamic properties.
