Description

technical field

[0001] The present invention relates to a fiber-reinforced resin composition and a molded body obtained therefrom. More specifically, the present invention relates to a carbon fiber-containing fiber-reinforced resin composition that reduces bending deformation of a molded article, and a molded article containing the same. Background technique

[0002] It is well known that fiber-reinforced polyolefin-based resins exhibit anisotropy in shrinkage rate due to fiber orientation when they are molded, resulting in bending or deformation. Therefore, their application to various applications is limited. When carbon fiber is used to reinforce polyolefin resin, compared with inorganic fillers other than carbon fiber, although the rigidity, strength, and heat resistance can be improved with a small amount of addition, it is easy to bend or deform, so This necessitates a method of reducing warpage.

[0003] Adding an elastic body (Patent Document 1) is known as a metho...
