Zusammenfassung:Process for the production composite articles, comprising the steps of:a) providing a curable mixture comprising:30-95 wt % of filler material, -5-70 wt % of resin, selected from unsaturated polyester resins, vinyl ester resins, (meth)acrylate resins, and combinations thereof,0.5-10 phr of at least one peroxyester,0.1-2.0 phr of at least one organic hydroperoxide,the weight ratio peroxyester/organic hydroperoxide being below 14.0,the curable mixture being essentially free of ketone peroxide,b) shaping the mixture, andc) heating the shaped mixture at a temperature in the range 60-100° C. to affect hardening of the resin and the formation of an article.
