The　Cf/TiC/Cu　composites　were　prepared　by　the　hot-pressed　sintering.　The　mechanism　of　interface　reaction　between　copper　and　carbon　fiber(Cf)　and　the　microstructure　of　composites　were　studied.　The　effects　of　Cf　content　on　the　density　and　bending　strength　of　Cf/TiC/Cu　composites　were　investigated.　The　results　indicate　that　the　transition　layer　with　TiC　as　the　main　phase　surrounding　the　carbon　fiber　is　generated　due　to　the　reaction　between　titanium　dissolved　in　the　liquid　copper　and　carbon　in　the　ternary　system　of　Cu-C-Ti.　A　film　of　Ti-Cu　compounds　maybe　covers　the　side　of　the　transition　layer　near　the　liquid　copper,　which　tightly　combines　TiC　with　copper　and　improves　the　combination　between　copper　and　carbon　fiber,　thus　the　properties　of　Cf/TiC/Cu　composites　are　improved.　When　the　Ti　content　is　certain,　the　properties　of　Cf/TiC/Cu　composites　get　worse　with　the　Cf　content(mass　fraction)　increasing.　When　the　Cf　content　is　5%,　the　synthetic　properties　of　Cf/TiC/Cu　composites　are　the　best,　the　resistivity　is　0.054　μΩ·m,　the　bending　strength　parallel　to　the　pressure　direction　is　237.90　MPa,　and　the　bending　strength　perpendicular　to　the　pressure　direction　is　237.44　MPa.
