| Résumé : |
Production costs for advanced composite aerospace components are directly related to part complexity. Touch labor content is substantial when parts with high levels of double curvature are fabricated by conventional hand lay up and autoclave cure. Automated forming processes have reduced the labor content of production parts with commensurable cost saving. However, such progresses are also limited by the level of double curvature present, as the tendency toward laminate wrinkling increases with part complexity. New material systems, based on aligned, discontinuous carbon fiber forms, offer the potential to increase the part of complexity spectrum available to these cost efficient automated forming processes. By offering additional deformation mechanisms, associated with fiber axis stretching, these materials alleviate in-plane and interply shearing requiments that constitute the principal process limitations of continuous fiber systems. This paper provides an overview of past and recent developement of this new class of material for composites forming. Examples of these material systems include LDF/PEKK, SBCF and Discotex. |
