Abstract
A new type of ceramic short fibers(ASZ fibers) was developed to fabricate cost effective metal matrix composites having mechanical properties superior to those reinforced with current commercial fibers such as Saffil or SiO₂ short fibers. Effect of the preform sintering temperatures on the mechanical properties of the Al alloy composites reinforced with ASZ fibers were studied to evaluate the composites as automotive applications. Both the crystallization sequence of the ASZ fiber and morphological change of the hinder used to prepare the preform were studied to determine the appropriate sintering temperature suitable for the preform fabrication, thereby enhance the mechanical properties of the resultant composites. Mechanical properties of the squeeze cast composites were measured as a function of the preform sintering temperature. Observations using SEM were carried out on the fracture surface of the fibers to analyze the varying mechanical properties associated with the sintering temperature. Interfacial reaction between the fiber and the matrix was discussed based on the experimental results obtained from SEM and TEM.
