A fiber reinforced gas turbine engine component

A gas turbine engine component comprises a fiber reinforced matrix. The matrix includes a crosslinked matrix including an R 1 group and an R 2 group, and/or an M group. The R 1 group and R 2 group independently comprise the formula: wherein V is a tetravalent substituted or unsubstited aromatic monocyclic or polycyclic linking structure; and R is a substituted or unsubstituted divalent organic radical. The structure for R 2 is different from the structure for R 1 . The M group, when present, is selected from the group consisting of a diamine structure, a dianhydride structure and an end group structure, with the M group being in the reacted or unreacted form. The crosslinked matrix has a glass transition temperature and a thermal oxidative stability sufficient to provide component stability for operational temperature up to about 550 °F.
