Abstract

A liquid crystal polyester resin composition including a liquid crystal polyester resin, 15 parts by mass or more and 100 parts by mass or less of a carbon fiber with respect to 100 parts by mass of the liquid crystal polyester resin, and 0.001 parts by mass or more and 0.02 parts by mass or less of a fullerene with respect to 100 parts by mass of the carbon fiber.

Claims (12)

1. A liquid crystal polyester resin composition comprising:

a liquid crystal polyester resin;

15 parts by mass or more and 100 parts by mass or less of a carbon fiber with respect to 100 parts by mass of the liquid crystal polyester resin; and

0.001 parts by mass or more and 0.02 parts by mass or less of a fullerene with respect to 100 parts by mass of the carbon fiber,

wherein the fullerene is adsorbed onto the carbon fiber.

2. The liquid crystal polyester resin composition according to claim 1 ,

wherein the fullerene has a fullerene structure containing a fullerene skeleton, and the fullerene is a mixture of a fullerene having 60 carbon atoms in the skeleton portion, a fullerene having 70 carbon atoms in the skeleton portion, and a higher fullerene having more than 70 carbon atoms in the skeleton portion.

3. The liquid crystal polyester resin composition according to claim 2 ,

wherein a content of the fullerene having 60 carbon atoms with respect to the total mass of the fullerene is 50% by mass or more and 90% by mass or less.

4. The liquid crystal polyester resin composition according to claim 1 , wherein the fullerene comprises an unsubstituted fullerene.

5. An injection molded body formed from the liquid crystal polyester resin composition according to claim 1 .

6. The liquid crystal polyester resin composition according to claim 1 , wherein the carbon fiber is a carbon fiber bundle in which a plurality of single fibers are bundled, and a number of fibers bundled in the carbon fiber bundle is 3,000 or more and 60,000 or less.
