TL;DR: In this article, the major findings of the Montana State University Composite Materials Fatigue Program from 1997 to 2001, and is intended to be used in conjunction with the DOE/MSU composite materials Fatigue Database.
Abstract: This report presents the major findings of the Montana State University Composite Materials Fatigue Program from 1997 to 2001, and is intended to be used in conjunction with the DOE/MSU Composite Materials Fatigue Database. Additions of greatest interest to the database in this time period include environmental and time under load effects for various resin systems; large tow carbon fiber laminates and glass/carbon hybrids; new reinforcement architectures varying from large strands to prepreg with well-dispersed fibers; spectrum loading and cumulative damage laws; giga-cycle testing of strands; tough resins for improved structural integrity; static and fatigue data for interply delamination; and design knockdown factors due to flaws and structural details as well as time under load and environmental conditions. The origins of a transition to increased tensile fatigue sensitivity with increasing fiber content are explored in detail for typical stranded reinforcing fabrics. The second focus of the report is on structural details which are prone to delamination failure, including ply terminations, skin-stiffener intersections, and sandwich panel terminations. Finite element based methodologies for predicting delamination initiation and growth in structural details are developed and validated, and simplified design recommendations are presented.

TL;DR: In this paper, a light-weight stiff celled composite sandwich panel is used to protect the LCD against breakage in a laptop computer using vibration-isolated threaded fasteners and double-sided adhesive foam tape.
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.
