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 withTi-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(4.4g/cm3),the density of Cf/TC4(3.6g/cm3)was significantly lowered.Under the quasi-static compression condition,Cf-/TC4 possesses yield and compressive strength of 1050 and 1250MPa respectively,compared with TC4,increasing 250 and 1OOMPa; Under the dynamic compression condition,Cf/TC4 possesses yield and compressive strength of 1500 and 1700MPa respectively,compared with TC4,increasing 500 and 300MPa.
