ABSTRACT:
An epoxy resin based composite is described with improved damping properties along with good strength and modulus of elasticity. The composition comprises a stiff epoxy such as epichlorohydrin-bisphenol A diglycydyl ether epoxy mixed with a flexible epoxy such as linoleic dimer acid glycidyl ester epoxy and a flexible cross-linking agent such as a long chain amine-fatty acid amide. The composition in admixture with high modulus fibers such as graphite forms composites with high damping properties, good strength and high modulus of elasticity. Typical uses for the composites of the present invention are flexural beams for hingeless-bearingless rotors and acoustical barrier material.
