Abstract
The effect of introduction of polyamide nonwoven materials on the thermal and mechanical properties of polymer composite materials based on phthalonitriles and a carbon fabric is studied. It is shown that the addition of 3 wt % of polyamide nonwoven material causes a 44% increase in the specific work of delamination. At room temperature elastic mechanical characteristics, such as compressive strength and compressive modulus, for the composite modified with the nonwoven material increase by 12 and 100%, respectively. According to dynamic mechanical analysis, upon reaching 169°C the melting of polyamide occurs; however, there remains the possibility to use the composites above this temperature, as confirmed by mechanical tests performed at 200°C.
期刊介绍:
Polymer Science, Series B is a journal published in collaboration with the Russian Academy of Sciences. Series B experimental and theoretical papers and reviews dealing with the synthesis, kinetics, catalysis, and chemical transformations of macromolecules, supramolecular structures, and polymer matrix-based composites (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
