摘要：
The effects of reinforcement morphology, volume fraction and test temperature on the flow behavior of SiC-borosilicate glass composites have been investigated in the present work. The deviation from Newtonian behavior of the matrix glass with the addition of reinforcements and subsequent shear thinning are observed. With the increase in volume fraction and aspect ratio of reinforcements, the strength and apparent viscosity of composites increase, but their rate sensitivity decreases. The activation energy for flow gradually drops with the increase in concentration of reinforcements. (C) 1998 Elsevier Science S.A.
