CELLULOSE FIBER-DISPERSED RESIN COMPOSITE MATERIAL, MOLDING, AND COMPOSITE MEMBER

Title:

CELLULOSE FIBER-DISPERSED RESIN COMPOSITE MATERIAL, MOLDING, AND COMPOSITE MEMBER

Document Type and Number:

WIPO Patent Application WO/2020/116517

Kind Code:

A1

Abstract:

Provided are: a cellulose fiber-dispersed resin composite material obtained by dispersing cellulose fibers in a resin, wherein the content of cellulose fibers is at least 1% by mass but less than 70% by mass, and if the length-weighted average fiber length of the cellulose fibers measured under the measurement conditions defined below is defined as LL, and the number-average fiber length is defined as LN, LL and LN satisfy formula 1; a molding using this composite material; and a composite member using this molding. Measurement conditions: LL and LN are determined using fiber length measurement method according to pulp-automated optical analysis stipulated by ISO 16065 2001 for the dissolution residual obtained by immersing the cellulose fiber-dispersed resin composite material in a solvent which can dissolve the resin in the composite material. Formula 1: 1.1<(LL/LN)<1.5
