SUPPLEMENTARY NOTES ABSTRACTThis final report outlines the research results obtained under the AFOSR Grant F49620-97-1-0160 for the period from 1 March 1977 to 31 December 1999. The research was partially augmented by the AASET Grant F49620-96-1-0283 for the period from 1 July 1997 to 31 December 1999.The main objective of the research was to develop a rational design/analysis methodology for a class of 3D braided structural shapes for aerospace applications. Research was carried out with two concurrent programs -the experimental program and the simulation programinvolving design, braiding of performs, consolidation and shape forming, fiber architecture determination and description, mechanics modeling, testing, investigation of preform braidability and formability at the consolidation stage.
