GAČR No. 18-10907S „Mechanical characteristics of polymer adhesive joints in civil engineering applications considering environmental effects and ageing“  2018-2020

An effectiveness, load-bearing capacity and safety of adhesive joints are influenced by quality, integrity and durability of adhesive bonds between adhesive and substrate. Project „Mechanical characteristics of polymer adhesive joints in civil engineering applications considering environmental effects and ageing” was focused on assessment of environmental ageing resistance of two adhesives to various metal substrates often used in civil engineering with the objectives to contribute to understanding and quantification of the ageing process of the structural adhesive joints. The prediction of mechanical properties of a joint under exposure to a certain environment is a complicated task due to the mutual interaction of various degrading effects, such as temperature, UV-radiation, moisture.
