摘要：
Effect of yarn structure on the aging of ramie fiber reinforced poly lactic acid（PLA）composites in water was investigated. The results show that ramie fibers have better dispersibility in R1/PLA composites than R3/PLA composites. There are more water absorption of R3/PLA composites compared with R1/PLA composites after aging. For both kinds of ramie/PLA composites，the interface between fiber and matrix became worse and the crystallinity of PLA is first increased and then decreased with the prolonged aging time. The R3/PLA composites has a faster aging rate，which leads to the lower mechanical properties than R1/PLA composite in late aging stage. The R1/PLA composites has better durability due to the good dispersion of the fibers，and can be used in construction work. © 2023 Tongji University. All rights reserved.
