ABSTRACT:
A LCD in a laptop computer is resiliently mounted to a light-weight stiff celled composite sandwich panel that protects the LCD against breakage. The composite panel comprises a layer of lightweight preferably aluminum honeycomb celled material that is sandwiched between inner and outer sheets of graphite epoxy material. The carbon fibers comprising the graphite epoxy material have their axes parallel to a plane of the composite panel and exhibit a high strength modulus, whereas the axes of the honeycomb cells are normal to the plane of the composite panel. The LCD is mounted to the composite panel using vibration-isolated threaded fasteners, and/or using double-sided adhesive foam tape. In addition to providing an attachment surface for electronic printed circuit boards, the composite panel advantageously provides a large dissipation area for thermal management.
