$a Production of high strength plywood from birch wood $f Vladimir Shamaev, Tatiana Efimova, Tatiana Ishchenko 215 $c Tab. 320 $a Lit. 330 $a Possibility for obtaining high strength plywood from birch veneer ( Betula pendula Ehrh . ) superior to beech ( Fagus Ehrh . ) plywood is studied. Plywood testing for ultimate split strength in adhesive layer, tensile strength and modulus of elasticity in static bending was conducted in accordance with the applicable Russian Standards . The experimental results showed that the samples of birch plywood, manufactured using processed ultrasonic adhesive, composed of hydrogel nanocrystalline cellulose and further processed with a pulsed magnetic field, have higher physical and mechanical characteristics: ultimate split strength on adhesive layer is increased up to 3.0 MPa, tensile strength under static bending – up to 118 MPa . Pressed birch plywood regarding strength in shearing on adhesive layer exc eeds beech plywood 2.5 times . Ultimate strength in static bending of pressed birch plywood increases by two times compared to standard birch plywood. 463 -1
