Analiza porównawcza siły niszczącej połączenia klejowe, klejowo-nitowe oraz nitowe stopu tytanu

The article presents comparative analysis of destructive force values for adhesive, adhesive-riveted and titanium alloy riveted joints that are widely applied in aircraft industry. An analysis was conducted of three types of assembly joints: adhesive, adhesive-riveted and riveted. The two joints variants differ in the length of the lap, number and distribution of rivets. The riveted and adhesive-riveted joints include two or five rivets. Moreover, two lap lengths were applied for all the tested joint types (i.e. adhesive, adhesive-riveted, riveted) 16 and 32 mm. In the case of single-riveted joints (i.e. 2 rivets) the lap length was 16 mm, while for the other sample (5 rivets) - 32 mm. The results of the tests led to an increase of the destructive force value in adhesive joints with the increase of the lap length. The observation was not the same for riveted and adhesive-riveted joints. The comparison of those three joint types of equal lap length indicated that the difference is negligible between destructive force value for adhesive-riveted and riveted joints, while the lower values are observed for the adhesive joints.
