ABSTRACT:
A method for molding a thermosetting resin pipe having a balanced compressive strength between the axial direction and the direction normal to the pipe axis is disclosed. The method includes steps of molding a thermosetting resin in a smooth zone in the front section of a screw to such an extent that the resin after being extruded from the cylinder is capable of retaining its own shape, and orienting the resin and/or a fibrous filler randomly. An apparatus for producing such a thermosetting resin, and a thermosetting resin having a balanced compressive strength are also disclosed.
