Experimental Investigation of Mechanical Properties of Moringa Oleifera Gum Filler Reinforced Bio Polymer Composite
Abstract
The effects of Moringa oleifera gum biofiller on the mechanical, viscoelastic, and biodegradability properties of epoxy-based composite materials were investigated in this study. Moringa oleifera biofiller gum was incorporated into the epoxy resin at varying volume percentages (4, 8, 12, 16, and 20 v/v%). Composite samples were produced using the hand-layup method. The experimental analysis revealed enhancements in the mechanical strength and viscoelastic properties, such as storage modulus and glass transition temperature of the composites, particularly at a biofiller volume fraction of 12% v/v. Thermal examination showed an increase in the thermal stability of the composite, which was attributed to the integration of Moringa oleifera gum biofiller. Scanning Electron Microscopy (SEM) imagery demonstrated a homogeneous distribution of Moringa oleifera gum biofiller throughout the epoxy matrix up to a biofiller volume fraction of 12% v/v, better than that of the unfilled composites or those with higher filler incorporations. This improved dispersion suggests an enhanced interfacial bonding between the biofiller and matrix, which in turn leads to superior mechanical properties and overall composite performance. The outcomes of this research highlight the significant potential of Moringa oleifera gum biofiller in advancing the performance and environmental sustainability of epoxy composite materials.
