Braiding is the novel textile technology which promises improvements in properties of composite material and being to meet the requirements of automated fabrication. Our purpose is to clarify the mechanical properties of braided composites. In this paper, we discuss the tensile properties of the flat plate with flat blading construction. The tensile specimen is made from glass fibers and epoxy resin by hand lay up method. Two kinds of the specimens are also fabricated for comparison purposes : a specimen with a braided flat bar cutting the side edge and a specimen reinforced with plain woven cloth. It is shown in the tensile test that the strength of the braided flat bar is larger than that of the other specimens. This reason for this finding is that the transverse crack leading to fracture in the braided flat bar is not initiated from the side edge where reinforced fibers are continuously oriented. This compared with the other types of specimens which consist of cut fibers at the side edge.
