ABSTRACT:
A thermal heat transfer member is disclosed for use with electronic or microwave systems. The thermal heat transfer member comprises a generally planar composite member is which elongated high thermal conductivity fibers are disposed within a matrix material. The matrix material may be an insulating epoxy or thermoplastic resin, while the fibers are elongated continuous commonly directed graphite fibers. The fiber ends terminate at a thermal contact surface which is interfaced with a heat sink. The thermal contact surface may be the transverse edge of the planar member or can be substantially parallel to the planar member. The fiber ends are inclined at an angle with respect to the plane of the planar member to provide for termination of the fibers at the thermal contact surface parallel to the planar member. Heat into the composite member is transferable along the commonly directed graphite fibers.
