ABSTRACT:
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.degree. C. below that of the first layer, or is an amorphous polymer having a glass transition temperature which is at least 10.degree. C. lower than the melting point of the polymer of the first layer, or is an amorphous polymer which may be crystallizable 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.
