Abstract: A meso scale three dimensional finite element model was setup to model two dimensional tri-axially braided composites. Unit cell scheme is used to take into account of braiding architecture as well as mechanical behavior of fiber tows, matrix and fiber tow interface. 0°/±60° braiding configuration has been studied. A failure criterion and progressive damage evolution model taking into account fiber tow and tow interface has been applied to theoretically predict inter laminar and intra laminar failure mode. Straight sided specimen testing was carried out in both axial and transverse direction. Results obtained in the tests as well as finite element approaches will be discussed. This paper will also discuss the main feature of the model through an extensive parameter study.
