Abstract
PURPOSE:To increase the rigidity and to decrease the internal loss, by laminating by bonding the graphite flake particles on an aluminum foil or an aluminum alloy foil by means of the resin into a pipe form. CONSTITUTION:A graphite resin layer 3 coated with a graphite flake 4 having 40-80mum thickness is provided on the surface of an aluminum foil 2 having <=40mum thickness. To increase the adhesive strength, an adhesion reinforcement resin layer 3 having 2-10mum thickness is provided on the rear side. These roll-up materials are wound around the outer circumference of a steel core material to receive an application of heat and pressure for hardening.
