The invention relates to ferrite compositions, particularly ferrite coated substrates and more particularly fibre plys coated with ferrites in fibre reinforced polymer composites (FRPC), and composites with a plurality of functionalised fibre layers The invention provides a magnetic ferrite composition for coating a substrate, said composition comprising a resin, and dispersed therein ferrite particulates, wherein said ferrite particulates have an average longest dimension of less than 500nm. The composition may be used to provide a ferrite composite structure comprising at least one fibre ply, with at least one layer of a magnetic ferrite composition deposed thereon, wherein said ply is substantially encapsulated in a binder matrix to form a fibre reinforced polymer composite. |
