However, further addition of clay led to negative effect on mechanical properties of
the HDPE/bamboo composite system. For the bamboo fiber-reinforced system, the
tensile strength increased almost linearly with increase of the MAPE content. Further,
the bending modulus and strength increased with MAPE loading up to the 4%–6%
level, but they began to decrease when more MAPE is added.
