ABSTRACT = {PLA composites containing biomass fillers from the three herbaceous plants such as reed, wheat stalk, and coconut fiber with length and diameter at the scale of several millimeters were prepared without using additives. The
reinforcement effect on the properties of PLA/biomass filler composites is investigated. The research results show
that the PLA/biomass filler composites exhibit good stiffness, flexural strength, and impact toughness. Among the
three kinds of biomass fillers, reed reinforced PLA composites show optimal mechanical properties. When filled
with 40%–50% reed, the flexural moduli of the composites are over 7000 MPa. Flexural strength retains at the
same level of pure PLA. The notch impact strength reaches to 4.50 ± 0.73 kJ/m<sup>2</sup>
, which is 2.06 times higher than
that of pure PLA. Furthermore, the introduction of biomass fillers increases the crystallization ability of PLA and
does not increase the water absorption of the composites. This research demonstrated that PLA composites prepared with biomass fillers from the herbaceous plants (namely herb plastic composites, HPCs) is a material with
good comprehensive mechanical properties while retaining the intrinsic particularity of biological sources.},
