Bamboo　fiber-reinforced　composites　(BFRC)　have　gradually　attracted　the　interest　of　researchers　due　to　their　excellent　mechanical　properties.　However,　the　age　factor　can　affect　these　composites＇　mechanical　properties　and　weaken　them.　This　study　aims　to　explore　the　mechanical　properties　of　BFRC　subjected　different　aging　tests.　First,　the　BFRC　is　prepared　from　raw　bamboo　through　a　series　of　technological　processes.　Second,　the　BFRC　sheets　are　processed　into　tensile　and　compressive　samples　with　different　directions.　Third,　the　samples　are　treated　with　a　cold-hot　test　and　a　UV　dry-wet　test,　respectively.　Finally,　quasi-static　experiments　are　carried　out　to　study　the　mechanical　properties　of　aged　BFRC.　The　results　reveal　that　the　BFRC　has　significant　anisotropy.　The　tensile　strength　of　BFRC　parallel　with　the　axis　of　the　reinforcing　fiber　is　as　high　as　148.53　MPa.　It　is　26.47　times　greater　than　the　tensile　strength　of　BFRC　perpendicular　to　the　axis　of　the　reinforcing　fiber.　The　mechanical　responses　and　SEM　images　show　that　the　UV　dry-wet　test　significantly　affects　on　the　BFRC　compared　to　the　cold-hot　test.　It　dramatically　reduces　the　mechanical　properties　of　the　BFRC.　The　SEM　images　further　indicate　that　cracks　occur　on　the　surface　of　BFRC　samples　under　the　UV　dry-wet　test.　In　addition,　two　aging　tests　have　an　interactive　effect　on　BFRC,　which　can　reduce　the　sensitivity　of　BFRC　to　a　UV　dry-wet　environment.　These　results　are　expected　to　deepen　the　understanding　of　the　mechanical　properties　of　BFRC　and　provide　guidance　for　its　applicable　conditions.　©　2023
