Abstract
The invention comprises a flat or shaped fabric structure of yarn groups each yarn group comprising a plurality of yarn subgroups, each group positioned for covering an area. The structure comprises at least a first group of flexible yarns densely covering an area , the yarns within the first group following substantially parallel paths in a first direction and forming a stack with at least a second group of flexible yarns densely covering substantially the same area, the yarns within the second group following substantially parallel paths in a second direction; the yarns in the first group arranged to cross the yarns in the second group, optionally containing other groups of yarn, the yarns in the upper-most subgroup of the stack are connected to the yarns in the bottom-most subgroup of the stack either directly of through the yarns in other subgroups providing an interlaced fabric structure.
