High temperature mechanical properties of high toughness metallic filament composites with polyimide and epoxy matrices

High toughness metallic filament was produced by glass-coated melt spinning. The high temperature mechanical properties of the composite consisting of the filaments uniaxially aligned in polyimide and epoxy matrices were investigated at the temperature range from 423 K to 573 K.

The Young's modulus of the composite (Ec) of the polyimide composite at temperatures up to 573 K was higher than that predicted by the linear function of the filament content (Vf) and the filaments fractured tightly in contact with the matrix. The epoxy resin composite had a excellent high temperature mechanical properties in spite of the low Tg of the resin and large thermal expansion mismatch between the filaments and the resin. The value of Ec at 573 K was higher than that of a linear function of the Vf and tensile strength of the composite (σcu) at 573 K agreed with the simple law of mixture. It is considered that some heat reaction of the resin occurred by incorporating the metallic filaments.
