The invention relates to the technical field of components of aviation and aerospace crafts, and particularly relates to an all composite material lightweight fuel tank shell for an aircraft. The whole structure is divided into three sections, namely a front conical section (100), a middle column section (200) and a rear conical section (300). The concrete structure comprises a conical section shell (1), a column section shell (2), a conical section shell (3), an L-shaped ring frame a (4), an L-shaped butt joint ring frame (5), an L-shaped ring frame b (6), a small omega-shaped ring frame (7),a large omega-shaped ring frame (8), an L-shaped ring frame c (9), an L-shaped butt joint b (10), an omega-shaped ring frame (11), a U-shaped ring frame (12), a main lifting point joint (13), a stopblock (14), a rear lifting point joint (15), a concentrated force decomposition structure (16) and an I-shaped beam decomposition joint (17). A cabin section is easy to integrally design and manufacture, high in overall rigidity, light in weight, simple in structure, capable of easily guaranteeing the sealing characteristic of the box body, high in adaptability to severe environments such as saltmist and the like.
