PERFORATED COMPOSITE STRUCTURES AND METHODS THEREFORE

摘要

Method including: (a) forming a laminate structure including a plurality of uncured prepreg sheets, wherein the laminate structure comprises an initial substantially planar configuration; (b) subjecting the laminate structure to suitable first curing conditions to provide a partially cured laminate structure while maintaining the substantially planar configuration; (c) providing the partially cured laminate structure with a plurality of perforations to provide a partially cured and perforated laminate structure; (d) shaping the partially cured and perforated laminate structure; and (e) subjecting the partially cured and perforated laminate structure to second curing conditions at least partially simultaneously with or after step (d) to provide a shaped and finally cured laminate structure.
