In this study, a combination of experiments and analyses are performed to characterize the structural response of two variable stiffness composite panels to a series of thermal and mechanical loads. This characterization covers all phases of the structure's lifetime from design through global failure. These panels are advanced composite structures in which the fiber orientation angle varies continuously as tows are laid down along predefined curvilinear paths within each ply. The panels are manufactured from AS4/977-3 graphite-epoxy prepreg using an advanced tow placement system. Both variable stiffness panels have the same nominal layup, but one panel (the panel with overlaps) has overlapping tow bands of varying thickness and the other panel (the panel without overlaps) has a theoretically uniform-thickness laminate. A conventional uniform-thickness panel with a straight-fiber [ 45]5s layup (the baseline panel) is also evaluated..."

The major objective of this book was to identify issues related to the introduction of new materials and the effects that advanced materials will have on the durability and technical risk of future civil aircraft throughout their service life. The committee investigated the new materials and structural concepts that are likely to be incorporated into next generation commercial aircraft and the factors influencing application decisions. Based on these predictions, the committee attempted to identify the design, characterization, monitoring, and maintenance issues that are critical for the introduction of advanced materials and structural concepts into future aircraft.

"Structural and Failure Mechanics of Sandwich Composites" by Leif A. Carlsson and George A. Kardomateas focuses on some important deformation and failure modes of sandwich panels such as global buckling, wrinkling and local instabilities, and face/core debonding. The book also provides the mechanics background necessary for understanding deformation and failure mechanisms in sandwich panels and the response of sandwich structural parts to a variety of loadings. Specifically, first-order and high-order sandwich panel theories, and three-dimensional elasticity solutions for the structural behavior outlined in some detail. Elasticity analysis can serve as a benchmark for judging the accuracy of simplified sandwich plate, shell and beam theories. Furthermore, the book reviews test methods developed for the characterization of the constituent face and core materials, and sandwich beams and plates. The characterization of face/core debonding is a major topic of this text, and analysis methods based on fracture mechanics are described and applied to several contemporary test specimens. Test methods and results documented in the literature are included and discussed. The book will benefit structural and materials engineers and researchers with the desire to learn more about structural behavior, failure mechanisms, fracture mechanics and damage tolerance of sandwich structures.
