In order to establish the application of a superplastic alloy as a matrix of fibre reinforced metals, bonding of fibre with metal matrix was investigated on the hot pressed composites. A superplastic zinc alloy was used as a metal matrix and a SiC multifilament fibre tow was embedded as a reinforcement in the composites. A bonding characteristic was investigated using an optical microscope.
Enough spreading of the fibre tow and favorable bonding of the matrix metal required a sufficient flow of metal matrix. The effect of bonding temperature on the bonding characteristic was negligibly small in the temperature range between 473 and 523 K. The bonding characteristic became critically worse as the number of fibre tows increased and the thickness of matrix metal plate decreased. The metal mold set in a hot press restricted the matrix metal flow, resulting in a poor bonding. The bonding characteristic in the composites was favorable without using the metal mold.
