The elastomeric nanocomposites having high mechanical stability and shape memory property were fabricated via in situ cationic polymerization of vegetable oil (linseed oil) in the presence of nano fly ash (NFA). The enhanced dynamic moduli and Young's modulus of nanocomposites with respect to matrix elastomers were witnessed. The vibration damping behavior of nanocomposites in wide frequency region, observed under a laboratory fabricated machine reveals their effectiveness to attenuate hazardous vibration in broad application regions. Under thermally stimulated shape memory test, the nanocomposites exhibit 100% shape recovery, and the shape recovery time improves when the content of NFA filler increases. © 2016 The Korean Society of Industrial and Engineering Chemistry.

This study deals with the preparation and characterization of elastomeric nanocomposites from renewable resources for vibration damping applications. The nanocomposites were synthesized by in situ cationic polymerization technique in the presence of organophilic montmorillonite (modified nanoclay) filler. The clay filled nanocomposites showed superior dynamic moduli in comparison with the pure elastomers. The storage modulus at room temperature (25 °C) was improved by 1.56 to 2 times with respect to pure elastomers with an increase in the filler content from 1 to 4 %. A good and stable vibration damping is observed in a wide temperature and frequency region (1-50 Hz). The loss factor, tanδmax obtained from dynamic mechanical analysis varies from 0.58 to 0.87. Under laboratory fabricated testing systems, the transient attenuation with the complete decay of applied vibration within nanocomposites demonstrates that the elastomeric nanocomposites have potential as effective damping materials.

Engineered elastomeric bio-nanocomposites from linseed oil/organoclay tailored for vibration damping

Vinylester resin matrix composites were prepared with a fly ash loading of 30, 40, 50 and 60 wt.-%. Flexural properties of the composites were investigated. It was found that the flexural strength was lowered in all the filled composites, but the flexural modulus showed a significant increase of 10,57,112% in case of 30,40 and 50 wt.-% fly-ash-loaded composites respectively, compared to the neat resin. However, there was a decrease in the mechanical properties in case of 60 wt.-% fly-ash-filled composites. The dynamic mechanical analysis was carried out to obtain information about the matrix-filler interaction at the interface. The storage modulus value at room temperature was highest for the 50 wt.-% fly-ash-filled composites, corroborating with the observed flexural modulus value. The fractured surfaces were examined under SEM and were correlated with the mechanical properties. © 2006 WILEY-VCH Verlag GmbH & Co. KGaA.
