摘要： A process for making a molded composite comprising the following steps: reacting a reaction mass containing a polyepoxide, in the proportion of about 20% to 50% with respect to the reaction mass, a diol, in the proportion of about 10% to 20% with respect to the reaction mass, a hardener, in the proportion of about 20% to 50% with respect to the reaction mass, in the presence of an accelerator in the proportion of about 0.5 to 10.0% with respect to the reaction mass either alone or in solution with compatible diluents, to obtain an epoxy resin mix having intrinsic viscosity in the range of 100 to 850 cPs, pouring the resin mix in a mold having an in-situ glass fiber scaffold at a mold temperature in the range of 45 to 50 C. and applying pressure to the resin mix in the mold to form a compressed green composition: partially curing the compressed green composition at a temperature in the range of 60 to 80 C. to obtain a partially cured composite; and further curing the partially cured composite at a temperature in the range of 80 to 90 C. to obtain a fully cured composite. The composite is used for structural applications like windmill blades, yachts, domes, ships made from a composite made in accordance with the process as mentioned herein.
