Abstract

Liquid oxygen compatibility is the key to evaluating whether carbon fiber reinforced epoxy composites (CF-composite) can be used in liquid oxygen environment. In this work, DOPO-PGE was prepared to improve the liquid oxygen compatibility of epoxy resin and CF-composite. The FTIR, ¹H and ³¹P NMR spectrum was used to confirm the chemical structure of DOPO-PGE. According to the UL94 test results, TG-FTIR, char residue analysis, and XPS analysis, the mechanism of DOPO-PGE affecting the liquid oxygen compatibility of epoxy resin is mainly attributed to the fact that the radical PO^[rad] released in the initial thermal decomposition stage of DOPO-PGE/epoxy can capture the highly active radical H^[rad], ^[rad]O^[rad], HO^[rad] and terminated the radicals’ chain exothermic reactions. The CF-composites show better liquid oxygen compatibility than epoxy resin matrix. However, the long-term liquid oxygen immersion can deteriorate the liquid oxygen compatibility of CF-composites.
