    摘要： A process for continuously manufacturing fiber reinforced plastic compounds is proposed comprising the steps of

    a) feeding a first stream of material to an extruder, wherein the said first stream of material comprises at least one fibrous component and at least one polymeric non-fibrous component,
    b) optionally feeding a second stream of material to the extruder, wherein the said second stream contains at least one polymeric non-fibrous component,
    c) melting the polymeric non-fibrous component(s) and mixing them with the fibrous component(s) in the extruder,
    d) transporting the mixture obtained in step c) through the extruder, thereby optionally passing a degassing and/or a pressure building zone,
    e) releasing the mixture obtained in step d) into a die,

    wherein at least one of the fibrous components of the first stream of material is a waste fibrous component.

    摘要： The invention relates to a single screw extruder having a means for the introduction of additives and to a method of introducing additives into a silicone rubber composition in the aforementioned extruder. A single screw extruder (1) comprising an elongate barrel (100) having an inlet (7) for introducing a polymer into the extruder and an outlet (5) for discharging extruded polymer from the barrel (100), a rotatable screw (6) axially disposed within the barrel (100) for advancing polymer in the extruder from the inlet (7) to the outlet (5), one or more additive introduction means (2) for introducing one or more additives at one or more predefined positions along the barrel (100) of the single screw extruder (1) between the inlet (7) and the outlet (5). Immediately upstream of the or each additive introduction means (2) there is provided, on or around the screw (6), a plug (12) having a plurality of apertures (20, 20a) which is adapted such that, in use, the only way for polymer or polymer/additive mixture to move downstream of the plug (12) is by passing through the apertures and that, having passed through an aperture, the polymer or polymer/additive mixture is subjected to a reduction in pressure and is simultaneously mixed with an additive from the one or more additive introduction means (2), prior to transportation of the resulting polymer additive mixture to the outlet (5). The extruder is typically used for the addition of additives such as cross-linkers and/or coloured pigments into high consistency silicone rubbers.
