The invention refers to a method for manufacturing a ring-shaped gasket (1) for an aircraft, comprising the following steps: providing a rod (2) made of prepreg composite material; providing a mold (3) having a female part (4) and a male part (5), at least one of the parts (4, 5) having a groove (6) with the ring-shaped desired configuration; placing the rod (2) onto the female part (4) and set the male part (5) over the ring-shaped rod to obtain a ring-shaped preform (7); applying vacuum to debulk the ring-shaped preform (7); curing the ring-shaped preform (7) to obtain a ring-shaped cured preform (9); and demolding the ring-shaped cured preform (9) to thus obtain a ring-shaped gasket (1).
