MANUFACTURE OF SHAPE REINFORCED BY FIBER

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.
