Fibre-resin composite body for providing electromagnetic shielding, comprising an electrical contact strip and method for making same

摘要

A method for fabricating a fiber-resin composite body for providing electromagnetic shielding. The body has a resin-impregnated fiber fabric and an electrically conductive fiber fabric, wholly or partially impregnated with resin material, one surface of the conductive fiber fabric having an uninsulated area wholly or partly covered with an electrical contact strip made of a wire mesh, which provides an electrical connection with the electrically conductive fiber fabric. The method includes placing the electrically conductive fiber fabric and the resin-impregnated fiber fabric in a mold, placing the wire mesh of the contact strip directly on the electrically conductive fiber fabric, covering the wire mesh of the contact strip with a sealing tape, and filling up the wire mesh of the contact strip completely with uncured resin material from the resin-impregnated fiber fabric so that only a front side thereof forms a contact surface free of resin. The method also subsequently cures the uncured resin and removes the sealing tape after the curing step has at least substantially ended.
