Zusammenfassung:A method comprises preparing or receiving a polyetherimide precursor solution including (i) a solvent comprising water, aliphatic alcohol, or a mixture thereof; (ii) an amine additive comprising a secondary or tertiary amine; and (iii) a polyetherimide precursor dissolved and dissociated in the solvent. The method further comprises at least partially coating or impregnating one or more reinforcement structures with the polyetherimide precursor solution and polymerizing the one or more polyetherimide precursor reagents to form a polyetherimide matrix such that the one or more reinforcement structures are at least partially embedded in the polyetherimide matrix to provide a composite article.
