RESIN COMPOSITE TYPE DAMPING PLATE EXCELLENT IN HEAT RESISTANT PEALABILITY AND RESIN PROTRUSION RESISTANCE, AND PRESS-MOLDED BODY AND CASE COVER FOR HARD DISK DRIVE USING THE DAMPING PLATE

摘要

PROBLEM TO BE SOLVED: To improve the reliability of an instrument by improving the cleanliness and confidentiality of a case cover by improving the peeling of a resin composite type damping metal plate (hereafter called a damping plate) and the protrusion of a resin at a baking temperature. SOLUTION: In the resin composite type damping plate and a press-molded body and the case cover for a hard disk drive using the damping plate, the intermediate resin layer of the damping plate is made a heat-curable amorphous viscoelastic body 20-80 mass% in gel fraction.
