Described herein is a fabric comprising: first fibers oriented in a first direction; second fibers oriented in a second direction; and a stitching yarn maintaining the first and second fibers in their respective orientations, the second direction being different to the first direction, wherein the first fibers comprise glass fibers and/or carbon fibers, and the second fibers are a texturized yarn.

A sizing composition for glass fiber direct roving for producing multiaxial fabrics is provided. The sizing composition includes, based on the total solids mass of the composition, 0.1 to 5.0% by solid mass of a first silane coupling agent, 2.5 to 11.0% by solid mass of a second silane coupling agent, 3.0 to 20.0% by solid mass of a first film former, 45.0 to 75.0% by solid mass of a second film former, 0 to 5.0% by solid mass of a plasticizer, 0.2 to 4.0% by solid mass of a first lubricant, 5.0 to 20.0% by solid mass of a second lubricant, and 0.01 to 3.0% by solid mass of a pH regulator. The first film former is a multifunctional epoxy emulsion, and the second film former is a low-molecular-weight liquid epoxy emulsion.

Herein is described a shapeable fabric comprising: first fibers comprising glass fibers oriented in a first direction: second fibers comprising glass fibers oriented in a second direction; and an intermingled stitching yarn (1) comprising a plurality of infusion filaments (4) and a plurality of shaping filaments (2) that are intermingled, wherein the second direction is within 0 to 90 degrees of the first direction, and the intermingled stitching yarn (1) forms a stitching pattern through the shapeable fabric and maintains the first and second fibers in their respective orientations, and wherein the shaping filaments (2) have a melting point of less than about 150 C. and the infusion filaments (4) have a melting point of at least about 180 C.
