Composite material for hot press molding and hot press molding

摘要

PROBLEM TO BE SOLVED: To provide a polyarylene sulfide resin composite material capable of producing a hot press molded product having excellent heat resistance and excellent dispersibility of a filler, and a hot press molded product using the same. SOLUTION: The polyarylene sulfide resin powder contains a polyarylene sulfide resin powder and a filler. The polyarylene sulfide resin powder has an average particle size of 5 μm or more and 100 μm or less, and a melting point Tm1 measured by a differential scanning calorimeter of 250. The above-mentioned problems are solved by using a composite material for hot press-molded articles, which has a temperature of not less than 300°C and not more than 300°C, and an average circularity measured by a dynamic image analysis method of not less than 0.70 and not more than 1.00. The water content of the polyarylene sulfide resin powder measured by a Karl Fischer moisture meter is preferably 0.1 ppm or more and 750 ppm or less. [Selection diagram] None
