All-plant fiber composite as a candidate for fully biodegradable material

摘要

Plasticization of China fir sawdust was carried out in the present work to prepare natural resources based plastics. It was found that thermoplasticity and mechanical properties of the chemically modified wood flour changed with the substitution reaction conditions. By compounding sisal fibers and the plasticized fir sawdust, unidirectional laminates were manufactured similar to conventional thermoplastic composites. Such an all-plant fiber composite material is characterized by easy processing, environment friendly and low cost. Instead of chemical heterogeneity of conventional composites, physical heterogeneity of the current natural fiber composite is favorable for interfacial interaction.
