To evaluate the fatigue strength of an actual car body in which aluminum honeycomb panels are applied as outside plates to improve pressure resistance while their requisite light weight and rigidity are being kept, fatigue tests were carried out for component models (general part and welded joint part of honeycomb panels). The results obtained are summarized as follows. (1) Fatigue strength for general part of honeycomb panels was 60 MPa (at 1 × 10^7 cycle). (2) Fatigue strength for welded joint part of honeycomb panels was 45 MPa (at 1 × 10^7 cycles). (3) Stresses of an experimental full-sized car body were under 30 MPa. Then an actual car body has a sufficiency of the fatigue strength reliability.
