Abstract
A chemical formulation having at least one polymer resin and an imine-based reactive diluent. The polymer resin is selected from selected from bis-Schiff base resins, phthalonitrile resins, benzoxazine resins, polyimide resins, phenolic resins, bismaleimide resins, polyether sulfone, and polyether ether ketone. The imine-based reactive diluent has the structure of Formula (A): where R10 is an aliphatic moiety or a hydrogen and R11 is also an aliphatic moiety or a hydrogen. Associated methods of making a polymer composite include infusing the chemical formulation into a carbon fiber reinforcement to form an uncured resin embedded composite and curing the uncured resin embedded composite to form a fiber-reinforced polymer composite.
