摘要

在测试异芳纶纤维粘合接头的强度时，采用了将纤维缆从拉成环结的粘合单元中撕出的方法，对比例因子的作用进行了研究。结果表明，粘合面积增加两个数量级（从 0.1 平方毫米到 10 平方毫米），接头的剪切强度就会降低一半。用 "环 "法测定的氰基丙烯酸酯粘合剂与所研究纤维的粘合接头强度值接近环氧树脂粘合剂和有机塑料的剪切粘合强度值。

The Scale Factor When Testing Adhesive Joints of Heteroaramid Threads Using the “Loop” Method

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.
