ABSTRACT The invention relates to a process for the fabrication of fiber-reinforced wound structures, and particularly pipe fittings, by impregnation of heat-resistant fibers with binders based on epoxy resins and 3-[1-(2'-aminoethyl)-1,3-diaza-2-cyclopenten-2-yl]-heptane and/or [1-(2'-aminoethyl)-1,3-diaza-2-cyclopenten-2-yl]-2,4,4-trimethyl-1-pentane as curing agent and commonly used fillers, pigments, dyes, accelerators, curing agents, wetting and flow-control agents, and reactive diluents. |
