An experimental loom was devised for the development of small samples of triaxially woven fabrics and was used to weave experimental amounts of fabric from coarse string, 3-ply, 840-denier nylon yard, and from graphite yarn. The shedding and warp yarn indexing motions are controlled by a series of cams mounted on a cam roll. The sequence of cams can be changed to produce various weave patterns changes in weave pattern can also be produced for any particular cam roll by varying the sequence of shedding and indexing motions. The nylon triaxial fabric and a range of square orthogonal fabrics woven from the same yarn were evaluated for various structural and mechanical properties. The stability of the triaxial fabric is much greater than that of an orthogonal fabric with the same percentage open area. The triaxial fabric exhibits greater isotropy in its bending behavior and a greater shear resistance than a comparable orthogonal fabric.
