Title:
RESIN COMPOSITION, MOLDED BODY, AND METHOD FOR PRODUCING RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2024/062840
Kind Code:
A1
Abstract:
The present invention provides a resin composition in which natural fibers are dispersed in a resin. The resin composition makes it possible to obtain a molded article having enhanced bending characteristics (bending strength, bending elastic modulus) and enhanced tensile characteristics (tensile strength, tensile modulus of elasticity). The resin composition includes a thermoplastic resin (A) and natural fibers (B). The average fiber length of the natural fibers (B) as measured by imaging with X-ray computed tomography (X-ray CT) is 32 μm or greater. When a cross section of the composition taken in the transverse direction is imaged by a scanning electron microscope (SEM) and a 1.8 mm × 1.2 mm range is measured, the ratio of the number of the natural fibers (B) to the average size (μm) of the natural fibers (B) (number/average size) in an image of the range captured at a working distance of 6.5 mm and x75 magnifying power is at least 400.
