ICA: C08J003-20. APPLICATION: JP 82-143335 20 Aug 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Compns. of novolak epoxy resins, brominated bisphenol A epoxy resins, N,N,N',N'-tetraglycidyldiaminodiphenylmethane (I), dicyandiamide (I) [461-58-5], and 3,4-dichlorophenyl-1,1-dimethylurea (III) [330-54-1], with novolak epoxy resin-I ratio 65--35, form fiber-reinforced composites having good heat resistance even after prolonged exposure to moisture. Thus, Araldite EPN-1138 [39362-23-7] (novolak epoxy resin) 65, I 10, DER-511 [37260-21-2] (brominated bisphenol A epoxy resin) 25, II 3, III 5 g, and Sb2O3 were combined in Me2CO-Me Cellosolve and applied to C fiber sheets, which when dried and laminated at 130° and 7 kg/cm2 for 90 min, gave boards having interlayer shear strength at 80° 9.0 kg/mm2 initially and 7.5 kg/mm2 after 14 days in water at 71°.
