Reinforcing wood by surface modification

The principal goal of this work was to establish quantitative evaluation of this effect. Samples with varying content of the polymer were subjected to stretching in order to determine material constants of single layers. To determine the influence of polymer content in the wood-polymer composite (W-P C) on its strength, the sample was subjected to the cylindrical bending. These experiments showed that the surface modification of wood resulted in uniform distribution of the stresses in the beam cross section. Numerical calculations of plates made of natural wood whose surface was modified and was subjected to bending, confirmed the results of laboratory tests.
