Abstract

As a completely biomass-based wood plastic composite material, a cellulose derivative (cellulose propionate, CP) composite material with added Erianthus fibers (EF) was developed. The biomass fiber EF was added to the cellulose derivative, and the rigidity of the cellulose derivative was greatly improved (tensile modulus improved by 149%). Although the strength decreased as the fiber content increased, it was revealed that it was possible to improve the tensile strength by preparing a cellulose derivative having an increased amount of residual hydroxyl groups and using it as a matrix component of a composite material (tensile strength is improved by 131%). Furthermore, it was confirmed that the thermal characteristics of this composite material are retained. Therefore, CP/Erianthus fiber achieved balanced thermal properties and better mechanical properties than petroleum-derived PP/MAPP composites.
