Posouzení využitelnosti vybraných listnatých dřev pro výrobu kompozitu na bázi dřeva
Kašpařík, Matěj
The bachelor thesis deals with the issue of the possibility of replacing spruce wood in the production of OSB with hornbeam and birch wood. The purpose of the thesis is to compare selected physical and mechanical properties of OSB made of these woods with standardized properties of OSB. In the first part, the origin, characteristics and current use of OSB are presented. The second part deals with the material and methodology of all the tests performed. The following properties of the boards were investigated: moisture content, flexural strength and elastic limit, density profile, swelling, delamination and shear strength of the glued joint. In the third part of the paper, the results of the tests and their comparison with the standard requirements for OSB are presented, followed by a summary and discussion.

The bachelor thesis deals with the assessment of the usability of alder and aspen wood for the production of wood-based composite, specifically the production of OSB. It uses the experimental analysis carried out to evaluate the applicability for sheating materials of timber frame structures. First section reviews particleboard with a focus on OSB. It summarises the importance, use and production of OSB panels and focuses on alternative raw material types for the production of wood-based composites. Describes the various technological processes involved in the production of OSB. The second part focuses on the individual production operations and shows the measurement procedures carried out. It also illustrates the determined data and the statistical methods applied to them. Based on the statistically processed data of selected physical and mechanical properties of the manufactured boards, it compares and evaluates the determined values with the requirements specified in standard ČSN EN 300, corresponding to the given application.
