Epoxide polymer matrices for high-strength and heat-resistant composites

摘要

Results of an investigation of the strength and thermophysical characteristics of epoxide materials based on epoxidated amines, resorcin, para-oxybenzoic and isocyanuric acids, and cycloaliphatic resins, i. e., vinylcyclohexene dioxide, in comparison with diane resin ED-20 and epoxidated phenol-formaldehyde novolak are presented. It is shown that the investigated epoxides contain 29-45% of epoxy groups, and cured polymers on their basis have maximal values of physicomechanical characteristics for the materials of this class described in the literature.
