Using the method of surface grinding, temperature of 80 ℃, and contact pressure curing, double-side adhesive repair of edge-cracked thick aluminum alloy plates is conducted by carbon fiber / bismaleimides composite materials. Performance of static and fatigue before and after repair is tested, and its kerosene resistance is examined by aging of high and low temperatures and normal temperature oil immersion test. The results show that the average damage load after repair increases from 94.313 kN to 143.593 kN, an increase of 52.25%; the fatigue life increases from 2 019 cycles to 34 698 cycles, an increase of 16.19 times; the critical crack length increases from 13.5 mm to 27.5 mm; the crack growth rate reduces from 2.72 mm/1 000 cycles to 0.59 mm/1 000 cycles. Under the oil immersion 300 cycles of high and low temperatures and 180 d of normal temperature oil immersion tests, the fuel has no effect on the fatigue performance of the test piece, and the repaired test pieces have no significant effect on the kerosene quality.
