Abstract

Graphical abstract: Highlights: Mechanical and creep properties of BFRPCs with various fiber loadings were studied. BFRPC with 60 wt% fiber exhibited the best flexural properties and creep resistance. The E ′ of BFRPCs above the T g of rPLA increased with increasing fiber loading up to 60 wt%. 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. Abstract: The present study investigates mechanical properties and creep resistance of bamboo fiber reinforced recycled PLA composites (BFRPCs). The results revealed that the modulus of rupture and modulus of elasticity of BFRPCs increased with increasing bamboo fiber loading up to 60 wt% and then declined sharply as the fiber increased further. Short-term accelerated creep tests on BFRPCs were conducted at a series of elevated temperatures by time–temperature superposition principle. As a result, the BFRPC with 60 wt% fiber exhibited the best creep resistance among all the BFRPCs, and then decreased when the fiber loading was more than 70 wt%.
