| Popis: | 1. For aluminum reinforced with steel fibers, increasing the fiber concentration to 50–60 vol. % produces only a small increase in the electrical resistivity of the composite. At higher fiber concentrations the rate of ascent of theϱ vs Vf curve sharply increases. 2. For titanium base composites reinforced with molybdenum fibers, at low reinforcing phase contents (of the order of 10–20 vol.%) the electrical resistivity of the composites decreases by a factor of more than 2 to 3 compared with the resistivity of the matrix. Subsequently, the rate of fall ofϱ slows down. 3. The experimental curves of resistivity vs composition and temperature for all the composites investigated are similar in character to the curves obtained analytically; however, the experimental values are slightly higher than the calculated results, by 3–4% for the aluminum base composites and by 10–12% for the titanium base composites. |
