Abstract
IMPROVEMENTS IN THE MANUFACTURE OF REINFORCED POLYESTER LAMINATES, characterized by that, they consist of using flat molds, perfectly smooth and polished, that are heated to a temperature of 80º, then applying on them one or two layers of polyester resins catalyzed to the 5 % of methyl ethyl ketone peroxide and after exactly 10 minutes, are placed on said layers of resin, printed fabrics or decorative papers, depending on the desired finish, even when it is not necessary to use these fabrics or papers, in which case sheets that resemble frosted glass will be obtained; then placed fiberglass embedded in polyester resins catalyzed by 4% methylethyl ketone peroxide, finally smoothing the surface placing the molds in hot press, using temperatures of 120º for 5 minutes, finally and after 36 hours at least , the plates obtained are polished to give them a matt, semi matt or glossy finish.
