Abstract
The role of the scale factor has been studied when testing the strength of the adhesive joint of heteroaramid fibers using the method of tearing out the tow from the adhesion cell formed by a loop pulled into a knot. It has been established that the shear strength of the joint decreases by half with an increase in the gluing area by two orders of magnitude—from 0.1 to 10 mm2. The value of the strength of the adhesive joint of cyanoacrylate adhesive with the studied fibers determined by the “loop” method turned out to be close to the values of shear adhesive strength for epoxy binders and organoplastics.
