Abstract: To improve fiber-metal composite structural integrity, a Fiber Metal Interpenetrating Composite Panel coated with Polyurea (P-FMICP) was prepared by braiding fibers into a perforated metal base and spraying a polyurea layer after curing with epoxy resin. Impact tests were conducted to investigate the effect of polyurea coating on the impact resistance of P-FMICP specimens. The results show that the polyurea coating improves the matrix toughness of FMICP, significantly extends the impact response time and absorbs energy, allowing the internal fibers to exhibit better tensile properties. The failure modes of the polyurea coating include shear failure and tear failure. The 2 mm thick polyurea coating increases the critical penetration velocity of FMICP by 94.92%, and energy absorption is enhanced by approximately 116 J. As the polyurea coating thickness increases, the total energy absorption of the specimen increases, but the specific energy absorption shows a decreasing trend. For P-FMICP with a 3 mm thick polyurea coating, the specific energy absorption is 1.8 J/g, which is lower than that of P-FMICP with 1 mm and 2 mm thick polyurea coatings (1.9 J/g~2.1 J/g). P-FMICP offers advantages such as lightweight and high specific strength, and research on P-FMICP provides technical references for the design of similar structures, optimization of impact resistance, and its engineering applications.
