摘要

摘要研究了 SVM 杂环芳纶纤维和氰基丙烯酸酯胶水粘合接头的耐热性，其依据是由拉紧成结的线圈形成的粘合单元中的粘合失效温度。首次获得了纤维与聚合物基体粘合接头在恒定剪切应力静载荷下的耐热性数据。以两种胶水为例，说明了胶水和纤维中的填料对聚氰基丙烯酸酯玻璃化转变温度和粘合接头耐热性的影响。计算了粘合失效的活化能，并证明粘合接头的热稳定性与剪切应力的关系属于阿伦尼乌斯类型。

Heat Resistance of Adhesive Joints of Heterocyclic Aramid Fibers under Static Load

The heat resistance of adhesive joints of SVM heterocyclic aramid fibers and cyanoacrylate glue has been studied based on the adhesion failure temperature in an adhesion cell formed by a loop tightened into a knot. For the first time, data on the heat resistance of adhesive joints of fibers with a polymer matrix under static load with constant shear stress have been obtained. Using the example of two types of glue, the influence of filler in the glue and fibers on the glass transition temperature of polycyanoacrylate and the heat resistance of the adhesive joint is shown. The activation energy of adhesion failure was calculated, and the dependence of the thermal stability of the adhesive joint on the shear stress was shown to be of the Arrhenius type.
