FIELD: fibrous structures, in particular, glass structures.
SUBSTANCE: fibrous structure comprises at least one layer of randomly distributed continuous yarns and at least one layer of reinforcing fabric such as layer of chopped yarns. Various layers of structure are joined to one another mechanically, by sewing or stitching, and/or chemically with the use of binder. Such structure may be produced by continuous or periodic process and is preferably used for manufacture of composite materials.
EFFECT: improved permeability and good deformation extent allowing this structure to be used for manufacture of various materials, preferably glass-based composites.
