    Abstract:
    Extrusion processing offers a new method by which pulps from recycled papers and sludges can be processed at ultra-high consistencies to form useful products. However, the method must surmount two problems. First, the fiber suspension must be made to flow homogeneously to achieve good formation. Second, processing equipment must disperse fiber flocs and transport the highly concentrated suspension. Through the extrusion method, mills can manufacture structural fiber composite materials with consistent, predictable properties. Stiffness losses caused by moisture can be controlled by the addition of crosslinkable resins.
