The aim of the Doctor's thesis was to develop plywood product with higher specific bending strength and stiffness properties in comparison with the traditionally produced plywood. The tasks of the thesis were: (1) to create plywood with I-core, corrugated core and plywood with one direction grain veneers in outer plies; (2) to test bending strength and stiffness characteristics; (3) to research of I-beam dimensions and geometrical parameters of higher specific strengthen plywood; (4) to develop solutions for manufacturing plywood of a large size with corrugated core; (5) to validate the plywood bending strength and modulus of elasticity calculation method for LVS ENV 14272:2003, based on the experimental results, reached by using plywood of different thickness; (6) to develop the proposals to improve the method (taking in account all veneers regardless of their grain direction).
