Abstract
Carbon fiber-reinforced titanium matrix composites were prepared by powder metallurgy. Carbon fiber (CF) powder and titanium (Ti) powder are mixed, pressed, and then sintered at a high temperature of 1300–1500 °C. The morphology and conductivity of carbon fiber-reinforced titanium matrix (Ti-CF) composites were studied. When the temperature range of the Ti-CF composites was from 1300 to 1500 °C, the porosity and resistivity first decreased and then increased. When the sintering temperature was 1350 °C, the diffraction peak of the sample was the strongest, the porosity was the smallest (4.16%), and the resistivity was the smallest (2.7 MΩ·mm). CFs have a very good strengthening effect on titanium-based composite materials.
