Epoxy resins are increasingly finding applications in the field of structural engineering. A wide variety of epoxy resins are available, and some of them are characterized by relatively low toughness. Several approaches to improve epoxy resin toughness include the addition of fillers, rubber particl
Cured unsaturated polyester resin was degraded with propylene glycol, and the degraded material was used to make recycled resin by reaction with maleic anhydride. The curing reaction for the recycled resin was faster than that of the neat resin. The mechanical properties of mixtures of neat and recy
