MAT WITH OPTIONAL ORIENTATION OF FIBRES, AND FORMED PRODUCT OUT OF FIBRE REINFORCED COMPOSITE MATERIAL Russian patent published in 2015 - IPC D04H1/64 

FIELD: machine building.

SUBSTANCE: formed product out of fibre reinforced composite material that is isotropic and has superior mechanical strength, and mat with optional fibres orientation used as intermediate material for formation of the composite material. The mat contains reinforcing fibres, in it the reinforcing fibres comply with the following provisions i) reinforcing fibres have weight-average width of the fibre (Ww) complying with the following equation: 0 mm < Ww < 2.8 mm(1); ii) the reinforcing fibres have ratio of dispersion through average width of fibre (Ww/Wn) determined as ratio of weight-average width of the fibre (Ww) to number average width of the fibre (Wn) equal to 1.00 or more, and 2.00 or below; iii) the reinforcing fibres have weight-average thickness of the fibre that is below weight-average width of the fibre (Ww).

EFFECT: production of formed product from the mat with optional fibres orientation, where the mat has small irregularity of thickness, being uniform in terms of the mechanical strength, and has superior tensile strength and high degree of strength demonstration.
