“…Epoxy resins (EP) are widely used in industrial blowers, aircrafts coatings, and rocket engine, due to their excellent mechanical properties, chemical stability, and corrosion resistance [1,2,3,4,5,6]. Especially in the aircraft flying speed below Mach 1.5, EP exhibit superior light weight, corrosion resistance and fatigue resistance compared to other resins [7,8,9,10,11]. Thus, in the coating on A400M and Boeing 787 aircrafts, the epoxy resin matrix accounts for 36% and 50% of the aircraft weight respectively [12].…”
