This present work focuses on a self healing mechanism incorporated within a carbon fiber reinforced polymer (cfrp) airframe of aircraft that is capable of curing micro cracks within the matrix autonomously (i.e. without human interaction, electric, chemical or thermal triggers)and restores the material properties, by a special polymerization reaction involving chemicals. in today’s aviation, the rigors of flight demand active research efforts aimed at the synthesis of robust materials that can withstand various extremes. the efficacy of incorporating a self-healing mechanism with reference to the airframe of lockheed’s f-35 lightning ii, (with a monomer di cyclo penta diene (dcpd)–healing agent in the presence of grubb’s catalyst) by using carbon nanotubes as re-inforcement of the polymer matrix is discussed. carbon fiber can be coupled with carbon nanotubes as they are comparatively stronger, lighter and have better mechanical and thermal properties. the nanotubes are coated over the carbon fiber in an aligned manner. the healing agent (dcpd) is alternatively laminated within the polymer matrix and the catalyst (grubb’s) is premixed with the matrix in the vicinity. when a crack is formed, dcpd, being a less viscous monomer, flows across the crack plane, reacts with the embedded catalyst by a ring opening metathesis polymerisation (romp) and solidifies and heals the affected surface. this will result in structures with longer lifetimes and lesser maintenance. the project is carried out theoretically and validated by experiments. the obtained results are compared with those of the present aerospace materials.
