| Abstract: | In the paper, the developing history and applying background of three dimen-sionally braiding composite materials are investigated. The basic "Unit Cell" structures of 3D braiding composite materials by various braiding processes and the effect of braiding processes on mechanical properties of integral structures are studied. The emphases are paid on the comparison of various braiding process, mainly two-step process and four-step process, with laminated composites. The photoelastic coating method is used to study the phenomenon of stress concentration around the hole in the 3D braiding composite materials. Some results are obtained. To consider the structural speciality of three dimensional textures, the normal temperature RTM technique is studied to model the test samples and high quantity samples are obtained. |
