Abstract [eng] The aircraft wing locks are made of carbon fiber roads that are glued to an epoxy resin. Due to the features of joining the wing parts, this examination is intended to form a database of mechanical properties of such of the adhesive bond. Investigated the carbon fiber adhesive joints through experimentally and numerically. The focus is on experimental and quasi-analytic strength adhesive bonding of one-sided and two-sided balanced and unbalanced joints, a few characteristics of the connections such as breaking and adhesive bonding strength, strength and durability of the joints. The numerical simulations of three-dimensional single lap and balanced and unbalanced double lap joints and finding influences of the structural adhesive and adherend stress distribution, delamination in various regions for suggesting the best and stress reduced joints for sailplane spar connection. Experimental research is a method for determining mechanical properties, but it is very expensive, especially the cyclic loading tests. This justifies the search for alternative methods that require cheaper devices and shortens time costs. The prepared ABAQUS and MATLAB models well describe the strength and durability of the joints and can be used for design and technical diagnostics.
