Title:
LIQUID CRYSTAL POLYESTER RESIN COMPOSITION, METHOD FOR PRODUCING SAME AND MOLDED BODY OF SAME
Document Type and Number:
WIPO Patent Application WO/2021/029265
Kind Code:
A1
Abstract:
The present invention relates to: a liquid crystal polyester resin composition which contains a liquid crystal polyester resin and carbon fibers with a sizing agent; and a method for producing this liquid crystal polyester resin composition. The content of the carbon fibers with a sizing agent is from 5 parts by mass to 120 parts by mass relative to 100 parts by mass of the liquid crystal polyester resin. With respect to the carbon fibers with a sizing agent, the adhesion amount of the sizing agent with respect to the carbon fibers is from 0.1 part by mass to 1.2 parts by mass relative to 100 parts by mass of the carbon fibers. If the carbon fibers with a sizing agent are heated from 25°C to 400°C in the air at a heating rate of 50°C/min, the mass loss rate within the range from 300°C to 400°C is less than 0.8% by mass.
