Abstract

This article describes preparation of polycyanurate binder, processed by the method of resin transfer molding (RTM). By the methods of HPLC, IR spectroscopy and DSC analysis the reaction of cyclotrimerization cyanate ester resin in the temperature range of 130 to 150°C is studied. The optimum mode of heat treatment is found for cyanate ester oligomer allowed to implement almost 100% conversion of the functional groups to obtain heat-resistant polymer matrix with Tg≥250°C on the basis of the received results. Fiberglass and carbon plastics based on the binder have a high level of strength properties, both at room and at elevated temperatures. The work is executed within the implementation of the complex scientific direction 13.1. «Binding for polymer and composite materials of constructional and special purpose» («The strategic directions of development of materials and technologies of their processing for the period till 2030»)
