Triaxial textile armature, process for producing triaxial textile armatures and composite material part

摘要

A triaxial textile armature is provided for making composite materials. The armature includes a central layer of axial yarns cross-linked by bias yarns extending in a first and a second direction the bias yarns extending in the first direction passing through the central layer of axial yarns in even intervals between axial yarns of the central, and the bias yarns extending in the second direction passing through the central layer of axial yarns in odd intervals.

1. Triaxial textile armature for making a composite material comprising a central layer of axial yarns, cross-linked by bias yarns extending in a first and a second direction, characterized in that the bias yarns pass alternatively over two axial yarns of the central layer and then pass under two axial yarns of the central layer, the passing through the central layer of axial yarns being separated by one interval between axial yarns of the central layer in order to prevent the bias yarns extending in the first direction and the bias yarns extending in the second direction from passing through the central layer of axial yarns in the same interval, the bias yarns extending in the first direction passing through the central layer of axial yarns in even intervals between axial yarns of the central layer, and the bias yarns extending in the second direction passing through the central layer of axial yarns in odd intervals.
