  • Bonding thermoplastic layers via electrical heating
    Patent number: 4871412
    Abstract: A method of bonding a thermoplastic layer (22), such as APC-2, to a substrate (21) in which the thermoplastic layer (22) comprises electrical conductors such as carbon fibres, embedded in thermoplastic material such as PEEK. The method comprises placing the thermoplastic layer (22) in contact with the substrate (21); and inducing electric currents in the conductors whereby heat generated by the currents passing through the conductors causes thermoplastic material to bond the layer to the substrate.
