A triaxial fabric comprising: a first plurality of yarns oriented parallel to each other within the plane of the fabric, a second plurality of yarns oriented parallel to each other within the plane of the fabric and a third plurality of yarns oriented parallel to each other within the plane of the fabric wherein, (i) the first, second and third pluralities of yarns (11, 12, 13) have a yarn orientation that is different from each other, (ii) the second plurality of yarns is interwoven with the first plurality of yarns. (iii) the third plurality of yarns is not interwoven with either the first or second pluralities of yarns, (iv) each yarn of the first plurality of yarns passes, in a repeat pattern and in order, over one yarn of the second plurality of yarns, over one yarn of the third plurality of yarns, over one yarn of the second plurality of yarns and then under one yarn of the second plurality of yarns, under one yarn of the third plurality of yarns and then under one yarn of the second plurality of yarns, and (v) each yarn of the second plurality of yarns passes, in a repeat pattern and in order, over one yarn of the first plurality of yarns, over one yarn of the third plurality of yarns, over one yarn of the first plurality of yarns and then under one yarn of the first plurality of yarns, under one yarn of the third plurality of yarns and under one yarn of the first plurality of yarns, characterized in that the yarns of the second plurality of yarns have an average linear density greater than or equal to the average linear density of the yarns of the first plurality of yarns and the yarns of the third plurality of yarns have an average linear density greater than the average linear density of the yarns of the second plurality of yarns and less than three times the average linear density of the yarns of the first plurality of yarns. a first plurality of yarns oriented parallel to each other within the plane of the fabric, a second plurality of yarns oriented parallel to each other within the plane of the fabric and a third plurality of yarns oriented parallel to each other within the plane of the fabric wherein, (i) the first, second and third pluralities of yarns (11, 12, 13) have a yarn orientation that is different from each other, (ii) the second plurality of yarns is interwoven with the first plurality of yarns. (iii) the third plurality of yarns is not interwoven with either the first or second pluralities of yarns, (iv) each yarn of the first plurality of yarns passes, in a repeat pattern and in order, over one yarn of the second plurality of yarns, over one yarn of the third plurality of yarns, over one yarn of the second plurality of yarns and then under one yarn of the second plurality of yarns, under one yarn of the third plurality of yarns and then under one yarn of the second plurality of yarns, and (v) each yarn of the second plurality of yarns passes, in a repeat pattern and in order, over one yarn of the first plurality of yarns, over one yarn of the third plurality of yarns, over one yarn of the first plurality of yarns and then under one yarn of the first plurality of yarns, under one yarn of the third plurality of yarns and under one yarn of the first plurality of yarns, (i) the first, second and third pluralities of yarns (11, 12, 13) have a yarn orientation that is different from each other, (ii) the second plurality of yarns is interwoven with the first plurality of yarns. (iii) the third plurality of yarns is not interwoven with either the first or second pluralities of yarns, (iv) each yarn of the first plurality of yarns passes, in a repeat pattern and in order, over one yarn of the second plurality of yarns, over one yarn of the third plurality of yarns, over one yarn of the second plurality of yarns and then under one yarn of the second plurality of yarns, under one yarn of the third plurality of yarns and then under one yarn of the second plurality of yarns, and (v) each yarn of the second plurality of yarns passes, in a repeat pattern and in order, over one yarn of the first plurality of yarns, over one yarn of the third plurality of yarns, over one yarn of the first plurality of yarns and then under one yarn of the first plurality of yarns, under one yarn of the third plurality of yarns and under one yarn of the first plurality of yarns, the yarns of the second plurality of yarns have an average linear density greater than or equal to the average linear density of the yarns of the first plurality of yarns and the yarns of the third plurality of yarns have an average linear density greater than the average linear density of the yarns of the second plurality of yarns and less than three times the average linear density of the yarns of the first plurality of yarns.
