Aluminum matrix hybrid composite reinforced with tungsten oxide particles (WO3p) and aluminum borate whiskers (ABOw), which have great specific gravity difference was fabricated by squeeze casting. The hybrid composite was observed by scanning electron microscope (SEM). The ultimate tensile strength, yield strength and elastic modulus of the hybrid composite are higher than those of matrix, but the elongation of the hybrid composite is relatively low. On the fractured surfaces of the composite the WO3p fractured and ABOw debonded from the matrix. The bonding strength of interface between reinforcements and matrix was found to be very weak comparatively. (C) 2008 Elsevier Ltd. All rights reserved.
