UMIST researchers have been attempting to solve the following problems associated with making three-dimensional textile structures: 3-D structures must be woven in two-dimensional form and then converted into the desired 3-D shape; and conventional looms produce fabrics using two systems of yarns--warp and weft--which are normally arranged at right angles to each other. Fabrics used as preforms must have yarns that are oriented at 45 or 60 degree angles. UMIST's research involves the study of the T-bar or double T cross-section, where the vertical component of the T-section is required to have as reinforcement two sets of parallel yarns at right angles to each other and at an angle of 45 degrees to the warp. A second method of weaving such a structure is proposed. Research concluded that not all three-dimensional structures can be woven on conventional looms.
