Title:
THERMOPLASTIC RESIN COMPOSITE MATERIAL, THERMOPLASTIC RESIN COMPOSITE MATERIAL PARTICLE, AND MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2021/256471
Kind Code:
A1
Abstract:
Provided is a thermoplastic resin composite material and a thermoplastic resin composite material particle which contain a cellulose fiber, can yield a molded article having excellent mechanical properties such as strength, and exhibit excellent molding processing properties by exhibiting excellent fluidity when molten. This thermoplastic resin composite material contains a cellulose fiber, a compatibilizer and a thermoplastic resin and is characterized in that the cellulose fiber contains essentially only a fiber having a fiber diameter of 1-50 µm and a fiber length of 10-400 µm, the compositional ratio based on the mass of the cellulose fiber and the mass of the thermoplastic resin is 10:90-80:20, and the thermoplastic resin composite material is such that the standard deviation of the areal ratio occupied by the cellulose fiber relative to a prescribed area is 15% or less in 10 arbitrary cross sections of the thermoplastic resin composite material.
