【MOLDED ARTICLE OF COMPOSITE RESIN CONTAINING FIBERS
Appl. No.: 16/814,648
Filed: Mar. 10, 2020
Applicant: Panasonic Holdings Corporation, Osaka (JP)
Inventors: Toshifumi Nagino, Osaka (JP); Masashi Hamabe, Osaka (JP)
Patent No.: US 11,660,791 B2
Date of Patent: May 30, 2023
In a method producing a molded article of a composite resin containing base resin and fibers, the composite resin containing a fibrous filler in the base resin and the fibrous filler including natural fibers with a fibrillated part on each end of the fibrous filler in a fiber length direction, the base resin and the fibrous filler are charged into a melt-kneading device. The base resin is melted and the molten base resin and the fibrous filler are kneaded in the melt-kneading device, thereby fibrillating only the ends of the fibrous filler. The obtained composite resin is discharged from the melt-kneading device and formed into a pellet shape, with the molded article of the composite resin produced by molding the pellets.

MOLEDE ARTICLE AND MOLDING METHOD THEREOF
Appl. No.: 15/842,337
Filed: Dec. 14, 2017
Applicant: Panasonic Holdings Corporation, Osaka (JP)
Inventors: Yuki Mita, Nara (JP); Shouma Nishino, Osaka(JP); Hideo Mine, Nara(JP); Masashi Hamabe, Osaka (JP); Toshifumi Nagino, Osaka (JP);
Patent No.: US 10,596,737 B2
Date of Patent: Mar. 24, 2020
A molded article 1 is made of a resin material 3 containing cellulose fibers 2. The molded article 1 has a surface portion 4 that is in a range satisfying T F≦0.1×T where T is the thickness of the molded article 1 and T F is a distance from the surface of the molded article 1, and the molded article 1 satisfies D F≧1.1×D where D is an average cellulose concentration of the overall molded article 1 and D F is an average cellulose concentration of the surface portion 4. Thus, the molded article suppresses an increase in bending modulus while considerably improving a tensile modulus.
