  • Patent number: 5219642
    Abstract: A structural thermoplastic composite material comprises a laminate of a first layer of a fibre reinforced thermoformable crystalline polymer composite and an adherent layer of a second thermoformable polymer which has been applied to the first layer at a temperature above the melting point of the polymer of the first layer. The second polymer comprises an amorphous polymer having a Tg which is at least 10.degree. C. lower than the Tm of the other polymer, which is crystallisable in a subsequent annealing process, and which has a peak crystallisation time of at least 1 minute. Such a material can be bonded to itself or to a different material by the adherent layer at temperatures below the Tm of the matrix polymer.

  • Patent number: 4541884
    Abstract: A process of producing a fibre-reinforced composition comprising drawing a plurality of continuous filaments through a melt comprising a mixture of a thermoplastic polymer and a plasticizer for the polymer in the weight ratio between 1:4 and 99:1 of polymer to plasticizer, preferably in the weight ratio 1:1 to 19:1, the plasticizer being thermally stable at least up to the temperature of the melt and having volatility characteristics such that the plasticizer can be volatilized from the composition below the decomposition temperature of the composition but has a sufficiently low volatility at the temperature of the melt to plasticize the polymer in the melt and give a melt of reduced viscosity compared with the melt viscosity of the polymer alone. The process enables higher molecular polymers to be used in the pultrusion process and enables higher fibre contents to be achieved.
