- Abstract
The aim of the following study was to examine the contractual compression strength and modulus of elasticity when compressing (MOEC) of three different wood composites with various structure types: softwood (coniferous) plywood, OSB and laminated particleboard 24 mm thick. The biggest MOEC value was performed by the particleboard laminated 24 mm MOEC equalling 70.00 N/mm². The second was found by the OSB panels, equalling 63.03 N/mm². Last, but with MOEC value close to OSB, was softwood plywood with MOEC of 62.44 N/mm². The lowest compression strength was observed by OSB samples, with a value of 2.75 N/mm². The second lowest value has been performed by coniferous plywood (2.80 N/mm²). The highest compression strength occurred by the particleboard laminated 24 mm, equalling 3.31 N/mm². Density shares and density profiles of the samples were also analysed, all of the examined composites performed U-shaped density profile The results of the study showed that there is no significant correlation between density and obtained parameters under compression. Observation of density share let the Authors conclude conversely than the results showed. It is supposed that the key factor affecting the compression performance of samples was the adhesive area and solid glue content within the composites. It is assumed that the bigger total contact surface of wood particles coated with adhesive resin, so the sum of the effective (gluing particles) surfaces of the adhesive joint is the better mechanical properties can be performed. This is why the laminated particleboard gave the best mechanical properties, while the worst were observed by the softwood plywood.
