%X An analytical laminate model was newly proposed to predict the ultimate strengths of two-dimensional tri-axial braided composites under in-plane loadings. The composite was modeled as a laminate possessing four plies. Among these four plies, there were three plies consisting of unidirectional fibers along with surrounding matrix and one ply containing only matrix. A progressive ply failure analysis was performed. A series of experiments were conducted. The present model was verified experimentally by using our and other researchers¡¯ data. Moreover, we compared this model¡¯s results with the numerical ones obtained by us. The results show that the present model has the potential to predict the effective elastic properties and ultimate strengths of two-dimensional tri-axial braided composites. Finally, the effect of the braid angle on the mechanical properties of a two-dimensional tri-axial braided composite was explored based on the mentioned model
