Abstract
Epoxy–guar gum-based composites are advanced materials that combine the excellent mechanical strength and chemical resistance of epoxy resin with the renewable and biodegradable characteristics of guar gum. These composites hold significant potential to meet the growing demand for high performance and environmental sustainability in the aerospace, automotive, and construction industries.In the present study, the dynamic mechanical properties of epoxy– allyl guar gum composites were evaluated using Dynamic Mechanical Analysis (DMA). The primary objective was to analyze the effect of incorporating allyl guar gum (AGG) with Different Degree of substituition DS-0.0389, DS-0.06 at various concentrations into the epoxy resin matrix. DMA tests were conducted to determine values for storage modulus, loss modulus, and tan δ across a range of temperatures and frequencies.The results revealed that the incorporation of Allyl Guar Gum significantly influences the viscoelastic behavior of the composites. Lower Concentration 0.5Phr) of AGG led to improved mechanical performance,
The thermal stability of the composites was also investigated using Thermogravimetric Analysis (TGA), providing insights into changes in decomposition temperature and char residue.
