An　idea　of　hybrid　composites　containing　carbon　fiber,　aramid　fiber　and　glass　fiber　was　proposed　in　this　paper.　Carbon　fiber　with　high　strength　and　high　modulus　was　used　to　ensure　the　enhancement　of　bearing　load,　glass　fiber　with　high　rupture　strains　was　used　to　achieve　the　ductile　behavior,　and　the　progressive　stress　transition　in　hybrid　fiber　sheets　was　realized　by　the　use　of　aramid　fiber.　A　series　of　4-point　bending　experiments　were　carried　out　to　investigate　the　effects　of　hybrid　mode,　hybrid　structure　and　layer　of　fiber　sheets　on　the　flexural　behavior　of　beams　strengthened　with　hybrid　fiber　sheets.　Results　show　that,　if　the　stress　in　hybrid　fiber　sheets　can＇t　be　transferred　stably,　the　local　debonding　between　hybrid　fiber　sheets　and　concrete　will　occur,　resulting　in　the　weakened　hybrid　effects;　with　the　same　total　layers　of　fiber　sheets,　the　cracking　load,　yielding　load,　maximum　load　and　ultimate　load　of　RC　beams　strengthened　with　carbon/aramid/glass　laminated　hybrid　fiber　sheets　are　respectively　22%,　12%,　12%　and　16%　less　than　that　of　the　RC　beam　strengthened　with　single　carbon　fiber　sheets,　while　the　displacement　ductility　index　increases　20%,　indicating　that　the　carbon/aramid/glass　hybrid　fiber　sheets　can　amend　significantly　the　brittleness　of　single　carbon　fiber　sheets.　Based　on　the　experimental　research,　an　elastoplastic　section　analysis　method　is　conducted　to　predict　the　bearing　capacity　of　RC　beams　strengthened　with　hybrid　fiber　sheets,　the　results　from　the　theoretical　predictions　and　the　experiment　agree　well.
