Abstract
A composite structure having isotropic strength properties and comprising a three-dimensional network of reinforcing yarns embedded in a body. The yarns are arranged in a plurality of groups, each group comprising a plurality of yarns arranged parallel with one another. The yarns of at least three of the groups are arranged so that the yarns of each of the three are directed in a mutually orthogonal direction with respect to the other two. At least one other group (or groups of yarns) is directed diagonally to the yarns of at least two of the three mutually orthogonal groups.
