Zusammenfassung:	A method for molding fiber reinforced articles with superior mechanical properties by injection molding. The method comprises heating a mixture of molding compound and chopped fiber to produce highly viscous substance. Pressure is applied to force the substance through an elongated injection slot oriented perpendicular to the major axial dimension of the finished article, causing the fiber planes to become oriented in a unique whorled, accordion like manner. The unusual fiber plane orientation reinforces the article such that it is resistant to crack propagation.
