Abstract
The shearing test of the unidirectionally reinforced aluminum matrix composite by a continuous Si-Ti-C-O fiber (Tyranno fiber(R)) was carried out to evaluate the bonding ability between the fiber and the matrix of this composite. Both longitudinal and transverse shear strengths were 0.13 GPa, and the fracture occurred at the matrix itself because of good wettability of the fiber for aluminum. The excellent compatibility of Si-Ti-C-O fiber for the aluminum matrix composite was found to be due to the mutual diffusion of aluminum atoms from the matrix to the fiber and also of silicon atoms from the fiber to the matrix after the fabrication of the composite.
