The F-35 Lightning II is an all-weather stealth combat aircraft that is intended to perform warfare strike missions and electronic surveillance capabilities at speeds up to 1.6 Mach.
Composites comprise 35% of the airframe weight, with the majority being bismaleimide, as well as some carbon nanotube-reinforced epoxy, which has a tensile strength of approximately 100 times greater than steel.
Any deviations in external dimensions can interfere with stealth capabilities, and at supersonic spe
