Abstract
The light carbon fiber/Ti-6Al-4V composite (Cf/TC4) investigated in the paper was fabricated by spark plasma sintering (SPS). Before the sintering process, copper (Cu) was coated on the surface of woven carbon fiber (Cf) to improve the wettability of Cf with Ti-6Al-4V alloy (TC4). The morphology, physical properties and mechanical properties of Cf/TC4 were characterized. Results show that Cf, with good interfacial bonding, is uniformly distributed in Cf/TC4. Compared with TC4 (4.4 g/cm3), the density of Cf/TC4 (3.6 g/cm3) was significantly lowered. Under the quasi-static compression condition, Cf/TC4 possesses yield and compressive strength of 1050 and 1250 MPa respectively, compared with TC4, increasing 250 and 100 MPa; Under the dynamic compression condition, Cf/TC4 possesses yield and compressive strength of 1500 and 1700 MPa respectively, compared with TC4, increasing 500 and 300 MPa.
