Mechanical dynamic analysis of banana fiber reinforced polymer matrix composites
CH Gangadhara Rao, A Nageswara Rao
Mechanical Dynamic analysis (MDA) could be a powerful technique for the characterization of the elastic properties of polymers. MDA measures the modulus (stiffness) and damping (energy dissipation) properties of materials as they're ill-shapen beneath dynamic stress. These measurements offer quantitative info regarding the performance of materials. this method are often wont to valuate a good style of materials like thermoplastics, composites, thermosets, elastomers, films, fibers, coatings and adhesives. MDA could be a valuable technique thanks to its high inherent sensitivity and is that the most sensitive thermal analysis technique for the measure of the glass transition regions, Tg. Secondary relaxation events without delay discovered by MDA, merely can't be detected by the other thermal technique. In the gift work, Banana and glass fiber were used because the reinforcement fiber and General Purpose rosin was used because the matrix for fabrication of Natural and Hybrid fiber bolstered composites (FRP’s). it's essential to judge the elastic properties of fictitious composites for improved mechanical and thermal properties. The dynamic moduli, mechanical loss and damping behavior as a perform of temperature of the systems were studied victimisation dynamic mechanical analysis (MDA). Within the gift work MDA was administrated on a fictitious Natural and Hybrid FRP’s. The fibers thought-about ar Banana & Glass, wherever physician rosin is taken into account as matrix. For MDA analysis fiber a lot of zero.5, 0.7 & 1.0 gram with a gradient are thought-about on each Natural & Hybrid FRP’s. The Storage Modulus (E’) values are found to be most for composites with one.0 gram fiber loading, indicating that the incorporation of Banana & glass fiber normally Purpose rosin matrix induces reinforcing effects appreciably at higher temperatures. The loss modulus and damping peaks were found to be lowered by the incorporation of fiber. The peak of the damping peaks trusted the fiber content.
