Abstract: Uncured epoxy resin for use in making prepreg for aerospace applications. The resin includes an epoxy resin component comprising difunctional epoxy resin, trifunctional epoxy resin and/or tetrafunctional epoxy resin and a sufficient amount of [3-(4-aminobenzoyl) oxyphenyl]4-aminobenzoate (3-ABOAB), as a curing agent, such that the uncured resin can be stored at room temperature of at least 6 weeks and wherein the uncured resin can be fully cured in no more than 2 hours at a temperature of between 175° C. and 185° C.

Abstract: An alternate resin-coated paper material for use in making honeycomb. The alternate resin-coated paper material is made from a paper that contains from 30 to 50 weight percent aramid fibers and from 50 to 70 weight percent of non-aramid fibers. A fire retarded phenolic resin is incorporated into the paper to make it self-extinguishing in less than 10 seconds with a self-extinguishing burn length of less than 12 inches when exposed to a 12-second vertical flame in accordance with the vertical burn test requirements set forth in 14 C.F.R. Part 25.583. The fire retarded phenolic resin includes a phenol formaldehyde resin and a phosphorous-containing fire retardant.
