Preparation and mechanical properties of palm fiber/polylactic acid composites

In recent years, the demand for environmental friendly materials based on biodegradable polymer and natural fiber has growth interest. In this work, a biodegradable composite from polylactic acid (PLA) and oil palm empty fruit bunch (palm fiber) were prepared by compression moulding. However t...
