H34552 ABSTRACT FIBRE REINFORCED THERMOPLASTIC COMPOSITE STRUCTURES A structural thermoplastic composite material comprises a laminate of a first layer of a fibre reinforced thermoformable polymer composite containing reinforcing filaments and an adherent layer of a second thermoformable polymer. The thermoformable polymer of the adherent layer comprises either a crystalline polymer having a melting point at least 10°C below that of the first layer, or is an amorphous polymer having a glass transition temperature which is at least 10°C lower than the melting point of the polymer of the first layer, or is an amorphous polymer which may be crystallisable in a subsquent annealing process. The adherent layer is applied to the first layer at a temperature above the melting point of the thermoformable polymer of the first layer.
