In the present work, amine-functionalized Prosopis juliflora carbon (APJC)-reinforced diphenyldiaminomethane-based cardanol benzoxazine (DDCBz) composites have been developed and characterized with a view to utilizing them for possible load-bearing and corrosion-resistant applications. Chemical structure of the DDCBz was ascertained using Fourier transform infrared, Proton nuclear magnetic resonance and Maldi mass spectroscopy. The 5 wt% APJC/DDCBz composites exhibit good hydrophobic character, thermal stability and mechanical properties compared to those of neat matrix and other wt% of APJC-reinforced composites. Similarly, glass transition temperature (Tg) and water contact angle of composites are enhanced according to their weight percentage concentration. Results from corrosion studies indicate that the mild steel specimens coated with DDCBz matrix and APJC/DDCBz composites offer enhanced corrosion resistance. Data obtained from different studies infer that the APJC-reinforced DDCBz composites possess an improved thermal stability, thermomechanical behaviour, hydrophobic characteristics and corrosion-resistant properties, which make them suitable for high-performance thermal and corrosion-resistant applications.
