Liquid crystal polyester resin composition

摘要

A liquid crystal polyester resin composition having an apparent melt viscosity of 10 to 100 Pa .sec at a shearing rate of 1000 sec<-1 >and at a flow temperature +40° C., obtained by compounding 10 to 100 parts by weight of an inorganic filler in the form of fiber and 10 to 100 parts by weight of an inorganic filler in the form of plate based on 100 parts by weight of a liquid crystal polyester resin, wherein the liquid crystal polyester resin contains at least 30% mol of a repeating structural unit of the following formula A1 and has a flow temperature of 270° C. to 400° C., the inorganic filler in the form of fiber has an average fiber diameter of 0.1 to 10 mum and a number-average fiber length of 1 to 100 mum, the inorganic filler in the form of plate has an average particle size of 5 to 20 mum, and the ratio (F/P) of the compounding amount (F) of the inorganic filler in the form of fiber to the compounding amount (P) of the inorganic filler in the form of plate satisfies the following equation;
