Mechanical properties and extended creep behavior of bamboo fiber reinforced recycled poly(lactic acid) composites using the time–temperature superposition principle

•Mechanical and creep properties of BFRPCs with various fiber loadings were studied.•BFRPC with 60wt% fiber exhibited the best flexural properties and creep resistance.•The E′ of BFRPCs above the Tg of rPLA increased with increasing fiber loading up to 60wt%.•Nearly perfect superposition of master curves was obtained using the TTSP method.•The modulus of all BFRPCs reduced in the range of 27–40% over a 30-year period.
