Study on Old Newspaper Recycling Fiber-Reinforced PLA Composites

Abstract

In the research, old newspaper recycling fiber-reinforced polylactic acid composites were produced by using injection molding technology. The influences of MAPP coupling agent and newspaper alkali deinking treatment on the performance of composite materials were studied. The results showed: MAPP can effectively improve the compatibility of old newspaper recycling fibers and PLA and increase the mechanical properties of composites; the alkali deinking treatment can effective improve the adhesion of newspaper recycling fibers and PLA and increase the mechanical properties of composites.
