Heat Resistance of Adhesive Joints of Heterocyclic Aramid Fibers under Static Load
Abstract
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.
期刊介绍：
Polymer Science, Series A is a journal published in collaboration with the Russian Academy of Sciences. Series A includes experimental and theoretical papers and reviews devoted to physicochemical studies of the structure and properties of polymers (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed. Online submission via Internet to the Series A, B, and C is available at http://polymsci.ru.
