Bismaleimide (BMI) is a high-performance thermosetting resin widely used in the aerospace, automotive, and mechanical and electronics industries due to its chemical and mechanical stability. It can act as a protective barrier against for steel and other metallic components which serve as magnets, aircraft components. Carbon Nanofibre (CNF) reinforced BMI has shown improved performance as advanced material which has been shown here with surface morphological changes along with the chemical protection imposed by BMI.
