PURPOSE: To make strength large to endure pressure or tension by using a plate made of titanium group metal as a metallic thin plate and boring a hole which passes through the respective layers of thin plates and sheets to pass a connecting member through the hole on complex materials.
CONSTITUTION: A link member is united by laminating metallic thin plates 1, 3, 5, 7, 9, 11, 13 and fiber reinforcing resin sheets 2, 4, 6, 8, 10, 12 alternatively. Every metallic thin plate 1, 13 is made of titanium group metal having 5-500μ in thickness. A hole 100 is bored to be extended in the direction to pass through the respective layers of the metallic thin plates and the resin sheet, i.e. a passing direction. Thus, its strength is increased and it can be endured pressure or tension enough.
