Abstract

To improve the toughness of the PLA/corn stalk composite, the introduction of polypropylene carbonate(PPC)was used. The PLA/PPC/corn stalk(PLA/PPC/CS)composite was prepared using a combination of melt extrusion and hot pressing. A single factor experiment was designed with hot pressing time, hot pressing pressure, and hot pressing temperature as variables, and the impact, bending, and tensile properties of the PLA/PPC/CS composite as evaluation indicators.The results showed that the hot pressing time, hot pressing pressure, and hot pressing temperature had significant effects on the mechanical properties of PLA/PPC/CS composites.The final optimized hot pressing process is: hot pressing time is 10 min, hot pressing pressure is 7.5 MPa, and hot pressing temperature is 190 ℃.

Key words： wood-plastic composite materials; polylactic acid; polypropylene carbonate; hot pressing process; mechanical property
