TITLE EPOXY RESIN FORTIFIERS BASED ON AROMATIC AMIDES INVENTORS Paul Douglas McLean Andrew Garton Robert Fredrick Scott Susan Elizabeth Gransden ABSTRACT OF THE DISCLOSURE The reaction product of (i) an aromatic amide having the amine group of the amide attached to an aromatic ring, and (ii) a mono- or di-epoxide, has been found to be a good fortifier of epoxy resins. Epoxy resins have been found to attain increased strength and modulus (yet not brittle) by compounding: (a) a resin-forming polyepoxide, (b) an amine curing agent for (a), and (c) the above fortifier; and heat curing the mixture. Strengths as high as 130-150 MPa and modulus values to as high as 5000 MPa have been achieved yet with a ductile mode of fracture.
