Abstract

PURPOSE:To cause compressive force by a press-forming die not to affect the eye hole-portion of a leaf spring by following method in which a bush dragging sheet, is inserted into a depression corresponding to eye hole-portion of a leaf spring formed in a lower die, and resin is filled in it and is hardened by heating under pressure. CONSTITUTION:A bush 4 dragging sheet 7 is inserted into a depression 6a of a lower die 6 which is previously formed correspondingly to an eye hole-portion 6a of the leaf spring 3. The sheet 7 is formed from a band like fiber which is penetrated by thermosetting resin and removes bubbles in it. After the predetermined resin is filled in it, they are press-formed by an upper die 5 and hardened by heating under pressure. Consequently, later working of the eye hole-portion becomes unnecessary, and the eye hole-portion of FRP leaf spring may be formed with low cost and high accuracy.
