JOINING MEMBER HAVING DIMENSIONAL CHANGE FUNCTION, JOINING STRUCTURE AND METHOD USING THE MEMBER

摘要

PURPOSE:To provide a joining member having a dimensional change function in which joining is performed with excellent strength at an optional working temperature by utilizing the dimensional change function of fiber reinforced composite material having thermosetting resin as a matrix. CONSTITUTION:A joining member 1 is formed in a shape to be inserted into a plurality of members 2, 3 to be joined by the fiber reinforced composite material having thermosetting resin as a matrix. The composite material is equipped with a dimensional change function in which compression stress given to the matrix at the predetermined working temperature is removed celed by heat treatment and the volume is increased. Therefor, both are strongly joined by heat treatment of the joining member 1.
