摘要： A process of producing a fibre-reinforced shaped article comprising extruding a composition comprising a settable fluid as a carrier for fibres at least 5 mm in length through a die so that relaxation of the fibres causes the extrudate to expand to form an open fibrous structure with randomly dispersed fibres as the extrudate leaves the die characterized in that the porous extrudate is compressed while the carrier is in a fluid condition into a shaped article. The process enables moulded articles to be formed having a random distribution of fibres the majority of which are at least 5 mm long.

摘要： Fibre-reinforced structures comprising a thermoplastics polymer and containing at least 30% by volume of reinforcing filaments extending longitudinally of the structure which have been produced in a continuous process and which have exceptionally high stiffness. The exceptionally high stiffness resluts from thorough wetting of the reinforcing filaments by molten polymer in the continuous process. The thorough wetting gives rise to a product which can be further processed even in vigorous mixing processes such as injection moulding with surprisingly high retention of the fibre length in the fabricated article. The continuous processes for producing the reinforced structures employ thermoplastics polymers having lower melt viscosities than conventionally considered suitable for achieving satisfactory physical properties.

摘要： A melt-processable composition comprising at least one polymer capable of forming an anisotropic melt and at least one other melt-processable polymer characterized in that the temperature range over which the polymer can form an anisotropic melt overlaps the temperature range over which the melt-processable polymer may be melt processed. The melt viscosity of such compositions may be very much less than that of the melt-processable polymer in the absence of the anisotropic melt-forming polymer particularly at high shear rates, corresponding to those encountered during moulding and extrusion operations. On the other hand at low shear rates and particularly when the concentration of anisotropic melt-forming polymer does not exceed 5% by weight increases in melt viscosity are obtainable which are valuable in fabrication processes operated at low shear rate where retention of form stability is required.

摘要： A method of producing a fibre reinforced structure by melt impregnation of continuous fibres with a thermoformable polymer melt comprising pre-wetting the filaments of the fibres with a composition containing a melt plasticizer for the thermoformable polymer, prior to introducing the pre-wetted fibres into the melt, optionally removing the plasticizer when the composition contains a polymer miscible with plasticizer to leave polymer coated filaments and introducing the pre-wetted filaments into a polymer melt, optionally a polymer melt containing a metal plasticizer for the melt and preferably removing the plasticizer from the composition by volatilization.The pre-wetted polymer coated filaments are useful materials as reinforcing fibres for use in processes other than direct melt impregnation. They can be used in the process known as film stacking impregnation or in processes involving initial impregnation using particulate polymers or alternatively in conventional extrusion compounding.

摘要： A process for impregnating a fibrous product, said fibrous product being a fabric woven from reinforcing fibres or a fabric of randomly disposed fibres, with a matrix polymer comprising causing partial impregnation of the fibrous structure by introducing the fibrous structure into a molten composition comprising the matrix polymer and a melt plasticizer for the matrix polymer and subsequently causing substantially complete wetting of the filaments of the fibrous structure by volatilizing the melt plasticizer from the partially impregnated structure at a temperature at which the polymer is molten, the melt plasticizer being thermally stable at the temperature of the melt and having volatility characteristics such that the plasticizer can be removed below the decomposition temperature of the melt but sufficiently involatile at the temperature of the melt to permit the viscosity of the melt to be reduced by comparison with the melt viscosity of the polymer at the same temperature. When a woven fabric is employed thermoformable composites can be obtained having short beam shear strength values at least 0.7 times the tensile strength of the plastics matrix material of the composite.

摘要： Compositions containing a polymer of PTFE and a polymer capable of exhibiting an anisotropic melt characterized in that the compositions contain between 0.05 and 99.5% of PTFE and 0.5 to 99.95% by weight of the polymer capable of forming an anisotropic melt. The presence of a minor amount of the anisotropic melt-forming polymer, that is, from 0.5 to 50% by weight of the composition enables the processability of PTFE to be improved, even to the extent of providing an injection mouldable PTFE composition. Compositions containing 20 to 50% by weight of PTFE confer benefits on anisotropic melt-forming polymers, such as lubricity and greater versatility in fabrication operations. Concentration of 0.05 to 5.0% by weight of PTFE are particularly suitable for modifying the viscosity characteristics of the low melt viscosity anisotropic melt-forming polymers so that such anisotropic melt polymers are less subject to problems such as flashing and jetting during moulding.

摘要： Articles are blow moulded from thermoplastic polymeric materials containing high proportions of fillers such as glass fibres. The method comprises extruding the filled polymeric material through a die having a mandrel for constraining the material into a tubular shape; coextruding between the die and the outer surface of the material, a liquid having a freezing temperature lower than that of the material; cooling the liquid and the outer surface of the material during their passage through the die to a temperature below the freezing temperature of the material but above the freezing temperature of the liquid while maintaining the inner surface of the material molten; squeezing the extrudate at suitable intervals to fuse the molten inner surface together and thereby seal discrete lengths; and inflating the sealed lengths to conform to a surrounding mould to produce laminar shapes which are then foamed-filled to give stiff panels.

摘要： 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.
