Abstract
The tensile strength of the aluminum tungsten fiber composite by the foil metallurgy technique and the aluminum graphite fiber composite by the high pressure casting technique were measured at the room and high temperature (450°C).
The aluminum tungsten fiber composite metal was made by the 17.3μ thickness aluminum foil and the 96μ, 16.8μ diameter tungsten fibers. The tensile strength and the young's modulus of these composites were measured at the room temperature. The fracture surfaces were observed by the electron scanning microscope.
The tensile strength of the aluminum carbon fiber composite metals (carbon fiber volume fraction: 5%, 8% and 16%) were measured at the temperature range from room temperature to the 450°C. Then the fractured surfaces were also observed.
The continuous tungsten fiber composite was excellent at the high temperature as expected from the rule of composite, but the tensile strength of the carbon fiber composite was not enough to the calculated value from the rule of composite.
The effective and economical production technique of the fiber reinforced metals are not yet found in this report.
