Abstract

A novel extrusion technology has been developed for multilayer plastics processing. The starting point of this work was well known problems with conventional extrusion heads: the marks from the spider legs and the weldline of the crosshead remain in the product and weaken its mechanical and electrical properties.
Uniform flow in the die exit is also difficult to obtain in a wider operational window. Another objective was the helical orientation of fibres, layer by layer, to create cross orientated structures.
