Document Type and Number:
WIPO Patent Application WO/2022/168459
Kind Code:
A1
Abstract:
A resin composite which comprises a resin and cellulose fibers, and is obtained by kneading the resin and pre-fibrillated cellulose fibers with a single- or multi-screw kneader. The pre-fibrillated cellulose fibers are ones which are obtained by mechanically processing a pulp and in which the content of fibers having a length of 0.1-0.5 mm, excluding 0.5 mm, is 40% or higher but less than 58% and the content of fibers having a length of 1.5-2.0 mm, excluding 2.0 mm, is 5% or higher but less than 10%. The cellulose fibers contained in the resin composite comprise 50 vol% or more cellulose fibers having an average fiber width of 1 μm or less.
