An adhesive bonding can be ranged among technologies of materials bonding which are used in all industrial branches. It plays its important role also in an area of the construction of agricultural machines, e.g. tractors, harvestors etc. Utility properties of adhesives can be extended by using various types of fillers. These fillers increase some mechanical characteristics of adhesives and not last they can decrease resultant price. The paper focuses on a possibility to fill the adhesives showing increased lap-shear tensile strength. These adhesives are used e.g. for adhesive bonding of coach bodies in an automotive industry so that is why it is possible to apply them also in the agricultural area. Laboratory experiments describe the lap-shear tensile strength of rigid adherents which were bonded with adhesives with a variable concentration of micro-particle filler – a glass powder. T-test used for a comparison of the shear strength of the bonds created with the adhesives with 5 vol.% of the glass powder did not evidence a statistically significant difference comparing with the unfilled adhesives. This priece of knowledge opens a possible way of a material usage of the glass powder in the area of the adhesive bonding.
