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, include 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 500 nm. 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 disposed thereon, wherein said ply is substantially encapsulated in a binder matrix to form a fibre reinforced polymer composite.

An electro-optic window is provided, together with a method of manufacturing the window. The window () is made of a material substantially transparent to at least one of infra-red, visible and UV radiation and treated to have reduced RF/MICROWAVE transmission characteristics by the provision of a grid () set into at least one surface () thereof. The grid () is formed of a material selected to be either reflective or absorptive to RF/MICROWAVE radiation.

Ferrite compositions, particularly ferrite coated substrates and more particularly fiber plys coated with ferrites in fiber reinforced polymer composites (FRPC), and composites with a plurality of functionalized fiber layers, include 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 500 nm. The composition may be used to provide a ferrite composite structure comprising at least one fiber 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 fiber reinforced polymer composite.

The structural health of a structure such as an aircraft is monitored by spraying a paint formulation containing a loading of carbon nanoparticles to provide a paint layer forming part of a paint system. The paint layer forms a smart skin whose electrical properties may be monitored to determine structural health.
