INJECTION-MOLDING OF SICW AL2O3 COMPOSITES

This investigation is a feasibility study of the injection moulding of alumina matrix composites reinforced with silicon carbide whiskers. T he flow properties of the ceramic/polymer blend with various polymeric binder systems were studied. The dispersion of the silicon carbide wh iskers in the ceramic/polymer blend from two mixing routes were compar ed. The ceramic weight composition and whisker length degradation of t he ceramic injection mouldings with various whisker content were explo red. As silicon carbide whisker may cause wearing on the processing eq uipment, an investigation on the samples' iron content was also carrie d out.
