An analytic model has been created which combines strength of Materials Micromechanic Theory and Laminate Plate Theory to estimate the mechanical properties of two hybrid braided architectures. These results are compared with test data to derive empirical "knockdown" factors which result from fiber crimping and jamming during the braiding process. Knockdown Factors are derived from E.., Ey, and G.,. In addition, the estimated coefficients of thermal expansion and Poisson's Ratio are compared with test data. By quantifying the empirical Knockdown Factors, more representative material properties can be utilized in engineering analysis for hybrid braided materials.
