FIELD: chemistry.
SUBSTANCE: invention relates to fibrous reinforcing materials - fibrous fillers or blanks for composite material and refers to band-like dry fibrous reinforcing material. Band-like dry fibrous reinforcing material (tape from gaps containing unidirectional reinforcing material) has channels or flow paths created by inclusion of a layer of separated bundles of fibres held by at least one adhesive layer. Invention covers also method and device for production of unidirectional tapes containing gaps.
EFFECT: invention provides creation of improved band-like fibrous dry reinforcing material due to better resin impregnation and/or more orientations in multi-axial structures, providing cost-effective production of composite materials.
