An attempt has been made in the present work to prepare hetero structured biobased benzoxazine-epoxy matrix composites using dairy farm waste based carbon as reinforcement. The prepared cow dung carbon(f-CDC) reinforced hetero structured biobased benzoxazine-epoxy composites and hetero structured benzoxazine-epoxy (HSBBz-EP) matrix are characterised using different analytical studies viz., FTIR, DSC, TGA, antimicrobial and anticorrosion studies in order to confirm the characteristic properties of the composites suitable for advanced applications. Data resulted from different analysis and characterisation ascertain that the prepared 5wt% f-CDC/HSBBz-EP composite sample possesses high glass transition temperature (199.90), better hydrophobic (water contact angle 113.60) behaviour , improved corrosion resistance (99.4%) in 3.5wt% NaCl solution, enhanced antibacterial (10mm) activity and higher thermal stability (293.8°C) with 5% weight loss. From the above results, it was concluded that the dairy farm waste based carbon reinforced biobased benzoxazine-epoxy composites developed in the present work can be used for different industrial applications.
