Abstract : This final technical report summarizes the research results obtained under Air Force Office of Scientific Research Grant F-49620-94-O3lS, which covered the duration from 1 July 1994 to 30 September 1996. The main objective of this research is to develop a rational analysis approach which accomplishments the rapidly advancing technology in Textile Composite Materials. Key results rendered are grouped and discussed in seven categories: (1) Modeling yarn architecture in preforms; (2) Local unit-cells and global cell-composition structures; (3) Mechanics modeling for local and global properties; (4) Geometric mapping of fiber architecture due to shape change;(5) preform braidability and deformability; (6) Experiment and testing; and (7) Correlations between model prediction and test results. Detailed development in each of the categories is contained in the seven papers which are appended as a part of this report.
