Abstract: Composites comprising structural fiber and matrix resin formulated from epoxys selected from the group consisting of polyglycidyl ethers of polycyclic bridged hydroxy-substituted polyaromatic compounds and N,N,N',N'-tetraglycidyl-bis(4-amino- 3-ethylphenyl)methane with from about 6 to about 150 pbw, per hundred parts by weight of the epoxy resin components, of a solid aromatic diamine hardener, toughened with porous rigid resin particles having a spheroidal spongy structure. The resulting composites exhibit surprising improvement in interlaminar strength characteristics as measured by G.sub.IC.

Abstract: Curable thermosetting resin compositions comprising at least one cycloaliphatic epoxy resin having at least two 1,2-epoxy groups per molecule, and certain aromatic diamines having three aromatic rings in the molecule are disclosed. Resin compositions comprised of, for example, bis(2,3-epoxycyclopentyl)ether and 1,3-bis(4-aminophenoxy)benzene exhibit a highly desirable balance of physical and chemical properties which renders such compositions ideally suited for use in the fabrication of wet winding composites. The resin compositions prepared in accordance with the invention have unexpectedly low viscosity, high glass transition temperatures, high tensile properties and unexpectedly low water uptake. Accordingly, the resin compositions find particular application in the preparation of composites by wet winding procedures.

Abstract: Curable thermosetting resin compositions comprising an epoxy resin having at least two 1,2-epoxy groups per molecule, an aromatic diamine hardener, and as a cure accelerator an aromatic trihydroxy compound are disclosed. The aromatic trihydroxy compound, such as for example, phloroglucinol, n-propyl gallate, or pyrogallol, improves the cure speed of the epoxy/aromatic diamine resin system, while at the same time producing cured compositions having excellent mechanical and thermal properties. The disclosed compositions find particular application in the preparation of composites by, e.g., filament winding procedures.
