The tensile properties of Al and Sn reinforced by E-glass fiber and SiO2 glass fiber were investigated. These composites were fabricated by the vacuum hot press process, using the foil metallurgy technique(1). The quantity of the glass fiber is up to 40 vol% in Al and up to 20 vol% in Sn. The conditions for pressing were as follows; 2 hours at 600°C in Al composites and 5 hours at 200°C in Sn composites under a pressure of 420 kg/cm2.
The composites reinforced by SiO2 glass fiber are more strengthened than that of E-glass fiber in Al and Sn, because of the difference in heat resistivity between the two kinds of glass fibers. And the Sn composites are also more strengthened than the Al composites. These results seem to be mainly due to the strength decrease in glass fiber, since no interaction between fiber and matrix has been observed by electron probe micro-analysis and microscopic examination and no fiber damages have been found during the fabrication. Moreover the relationship between the shear stress of matrix, τm and critical aspect ratios has been discussed.
