Abstract
The truss type honeycomb panel is three laminar structure that sandwiched a core part molded as wave pattern with two pieces of plates. The core parts of the wave shape molded by press or extrusion molding and produced more relatively easily than general honeycomb panel with a core of the hexagon. This truss type honeycomb panel was analyzed, and it was examined the influence that core shape gave stiffness and strength of the whole panel. The maximum stress became higher in a neighborhood of the joint with the core part and the surface plate. The stress did not decrease when fillets added to the joint parts,. When a cross-section of the core part became triangular, strength and stiffness increased.
