“PRE-IMPREGNATED COMPOSITE MATERIAL WITH NO EXPIRATION DATE, AND ITS PREPARATION PROCESS”

The present invention relates to a pre-impregnated composite material with no expiration date that can monitor its curing process through resistive heating, as well as its manufacturing process. This material is based on fiberglass and a vitreous resin reinforced with electrically conductive nanoparticles. 10 Therefore, the present invention focuses on the field of composite materials that can be used, for example, in the aerospace sector, the wind power sector, the naval sector, or the automotive sector, although it can be extended to any other sector that manufactures long fiber composite materials.
