Shear controlled orientation technology for the management of reinforcing fibres in moulded and extruded composite materials

The controlled application of macroscopic shears to solidifying melts containing alignable constituents provides for the management of fibres in, and the production of components to close tolerances. Shear controlled orientation technology (SCORTEC) may be applied to the thermoplastic and thermoset matrix composites, and to ceramic and metal matrix composites processed with the aid of sacrificial polymer binders. The principles of SCORTEC as applied to moulding and extrusion processes will be described, together with examples of typical property enhancement possible, and potential fields of application.
