A layered bamboo-plastic composite (BPC) consisting of bamboo (Phyllostachys makinoi) particles and
polypropylene was investigated. The influence of the layering conditions, including the thickness and bamboo
content in various layers, was the focus in terms of the
physicomechanical and creep properties of the BPCs. The
results showed that a three-layered BPC (BPC3L) with a 1:3:1
thickness ratio and with top/bottom layer containing 40%
bamboo exhibited the best specific flexural properties. An
accelerated creep test approach was applied, known as
the short-term stepped isostress method (SSM), to predict
the long-term creep behavior of BPC3L. The results indicated that the creep master curves, which are constructed
from different SSM testing parameters, agree well with
the long-term experimental creep data and that the creep
resistance of homogeneous single-layered BPC was better
than that of BPC3L.
