Static load tests were carried out for component models and an experimental full-sized 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. The results obtained are summarized as follows. (1) Tensile strength for general part of honeycomb panels were 240〜250 MPa. (2) Tensile strength for welded joint part of honeycomb panels were 194〜198 MPa. (3) Bending strength of a honeycomb panel was approximately 170 MPa. (4) Shearing strength of a honeycomb panel was at least 77 MPa. (5) Stresses of an actual car body were under 30 MPa. Then an actual car body has a sufficiency of the strength reliability.
