FIBER-REINFORCED MULTILAYERED PELLET, MOLDED ARTICLE MOLDED THEREFROM, AND METHOD FOR PRODUCING FIBER-REINFORCED MULTILAYERED PELLET
Document Type and Number:
WIPO Patent Application WO/2015/115408
Kind Code:
A1
Abstract:
A fiber-reinforced multilayered pellet having a sheath layer and a core layer, wherein the fiber-reinforced multilayered pellet is characterized in that the sheath layer is configured from a resin composition containing a thermoplastic resin (a1) and a fibrous filler (b1), the weight-average fiber length (Lw) of the fibrous filler (b1) being from 0.1 mm to less than 0.5 mm, and the ratio (Lw/Ln) of the weight-average fiber length/number-average fiber length being from 1.0 to less than 1.8, and the core layer is configured from a resin composition containing a thermoplastic resin (a2) and a fibrous filler (b2), the weight-average fiber length (Lw) of the fibrous filler (b2) being from 0.5 mm to less than 15.0 mm, and the ratio (Lw/Ln) of the weight-average fiber length/number-average fiber length being from 1.8 to less than 5.0. Provided is a fiber-reinforced multilayered pellet permitting a high level of filling by fibrous filler and having exceptional productivity, fluidity, and mechanical properties of the molded articles obtained therefrom.
