Vliv ligninu ve funkci plniva na pevnost lepených spojů materiálů na bázi dřeva
 Klonová, Sára
Analysis of the effect of lignin added in various amount to binders containing thermoreactive resins commonly used for bonding wood-based materials is a main theme of this thesis. Itʼs also related to a similar problem analysed in the bachelor thesis – influence of added lignin into heat-activated adhesives, so it can complete already obtained results with some new findings by a change of analysed wood-based material. Practical part of this thesis is focused on a strength of adhesive joints bonded with binders that contain different amount of lignin. Adhesives are applied on a surface of testing samples made of ash and larch and then climatized in a various moisture condition. The tensile strength, shear tensile strength and flexural strength of adhesive joints are being tested. Thesis provides application of obtained results of utilisation of lignin as filler of adhesives used for bonding wood-based materials exposed to specific physical – mechanical factors in practice.
