Abstract
Composite textile material for the production of composite articles, consisting of a multilayer structure, the various layers being joined together by needling. It is characterized in that it comprises at least two woven layers: one of which is based on yarns with high mechanical performance (for example aramid); and the other of which is based on yarns of another kind and more particularly continuous filament glass yarns, the two woven layers being bound together by needling so that a minor part of the high mechanical performance fibres is implanted within the woven glass yarn structure.
Claims4
A composite material having a planar, aerated structure, for use in the production of composite structures that includes:
- a multi-layered structure consisting essentially of at least two superimposed woven yarn layers, one of said yarn layers being formed of non-twisted glass filaments and the other of said yarn layers being formed of non-twisted strands selected from the group consisting of aramid and carbon fibers having a higher mechanical strength than the glass filaments;
- and
- needling means for joining the two woven layers so that a portion of the strands of high mechanical strength are implanted within the glass filament yarn.
