“…It is known that the bond strength decreases when the amount of powder added to the pure adhesive is higher than a certain amount (threshold value). In the studies verifying this statement, metal powders are generally used as the additives [44]. The results of the experiments performed using olive pomace, walnuts, and mussels with a size of 38 µm are consistent with the literature.…”

The most important advantages of adding additives to adhesives are increasing the bonding strength and reducing the adhesive cost. The desire to reduce costs as well as the need for environmentally friendly and health-friendly products have paved the way for the recycling of waste materials and the use of cheaper natural materials as additives. In this study, mussel, olive pomace, and walnut powders in different ratios (5%, 15%, and 30% by weight) and in different sizes (38 and 45 µm) were added to an epoxy adhesive. The steel materials were joined in the form of single-lap joints by using the obtained adhesives with additives. These joints were subjected to the tensile test and the strengths of these joints were examined. SEM images of the bonding interface were taken, and the distribution of the powders was examined. When the powder size was 45 µm, bond strengths increased in all additive ratios compared to the pure adhesive, while for 38 µm powders, the strength value increased only at the 5% additive ratio. In joints with 45 µm powder additives, the strength increased by up to 38% compared to the pure adhesive, while this rate was determined as 31% for 38 µm.

“…This bonds fail in a cohesive mode (failure within the adhesive) due to the high stress levels generated in the adhesive, which indicates that the adhesion to the metal surface is stronger than that of the interior part of the adhesive. Kavak and Altan (2012) investigated epoxy resins fi lled with particles of 63/37 Sn-Pb. Their experimental results show that bonds prepared by adhesive which was modifi ed, adding the amount of 5 wt% of 63/37 Sn-Pb powder, are of hogher mechanical strength than bonds which are prepared by adding aluminium powder with diff erent ratios as 5, 25, 50 wt%.…”

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 fi llers. These fi llers increase some mechanical characteristics of adhesives and not last they can decrease resultant price. The paper focuses on a possibility to fi ll 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 fi ller -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 signifi cant diff erence comparing with the unfi lled adhesives. This priece of knowledge opens a possible way of a material usage of the glass powder in the area of the adhesive bonding.
