Title:
FIBER-REINFORCED THERMOPLASTIC RESIN FILAMENT AND FABRICATED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2022/270320
Kind Code:
A1
Abstract:
The present invention provides: a fiber-reinforced resin filament characterized by comprising a thermoplastic resin (A), a fibrous reinforcing material (B) having a fiber length of 3-9 mm and a fiber diameter of 5-20 μm, and an elastomer (C); and a fabricated article. The present inventor has found that, with this fiber-reinforcing resin filament, a thermoplastic resin filament for 3D printing capable of being reeled in can be obtained, and that a fabricated article obtained from the heat-fusion additive fabrication carried out with this thermoplastic resin filament demonstrates favorable mechanical properties. This finding led to completion of the present invention.
