20150037561 | EPOXY RESIN FORMULATIONS FOR TEXTILES, MATS AND OTHER FIBROUS REINFORCEMENTS FOR COMPOSITE APPLICATIONS - This invention relates to epoxy resin formulations for preforms to be used in molding processes, especially resin transfer molding processes and to methods for preparing the performs. The epoxy formulation is based on liquid or solid epoxy resins blended, with medium to high molecular weight, phenoxy resins. These formulations are highly compatible with epoxy curable injection resins, and more over are reacted in the polymeric matrix, without reducing the glass transition temperature (Tg) of the cured composite material. | 02-05-2015 |
