Abstract
The use of very low concentrations of carbon nanofillers selected from among carbon nanotubes, carbon nanofibers, graphene or a mixture of same in any proportions, in order to improve resistance to ageing, in particular protection against ultraviolet (UV) light, of a composite material based on a polymer matrix. A composite product comprising a composite material, the composite material stabilized with respect to UV light using a content of between 1 ppm and 0.1% by weight, of carbon-based nanofillers chosen from carbon nanotubes, carbon nanofibers, graphene or a mixture of these in all proportions, wherein the composite product is selected from yarns, films, tubes, fibers, and nonwovens.
