Pevnost lepeného spoje ve smyku materiálů na bázi dřeva v extrémních podmínkách
Hromádka, Petr
This thesis deals with the issue of adhesive joints under extreme conditions. The aim of this work is to determine influence of temperatures -30 °C, +23°C, +70 °C on maximal tensile strength of adhesive joint and to determine which adhesive has the best results when used on specific agglomerated materials. Manufactured samples (chipboard, chipboard press-veneered by spruce, fibreboard, beech plywood board) were used in process of solving the task. These samples were used in accordance with standard ČSN EN 205. Data were processed by software and evaluation was accomplished by using statistical methods. As a result of a detailed research the adhesives appropriate for use in extreme conditions on Earth were determined. Contribution of this work is clarification of the impact of exposure temperature, type of adhesive and interaction between temperature of exposure and type of adhesive. Based on obtained results appropriate type of adhesive for given temperature during maximal tensile stress can be recommended.
