The melt flow index measured under the condition of a load of 16 kg is 0.06 to 300 g / 10 min, preferably 0.1.
1 to 200 g / 10 min, more preferably 0.15
A resin in the range of up to 150 g / 10 min is used. The polyacrylonitrile fiber in the present invention is an acrylonitrile homopolymer or a polyacrylonitrile polymer fiber composed of a copolymer of 90% by weight or more of acrylonitrile and 10% by weight or less of a vinyl monomer copolymerizable with acrylonitrile. It is a fiber produced by a known method for producing a polyacrylonitrile-based polymerized fiber. Preferably, the fineness is 0.5 to 50 denier, the tensile strength is 2.5 g / d or more, and the initial elastic modulus is 30 g / d or more,
Even if it has a physical property out of this range, it can be used in the present invention. The fiber length of the polyacrylonitrile fiber is preferably 0.5 to 20 mm. If it is less than 0.5 mm, industrial production is difficult. Further, in order to exert a reinforcing effect, it is preferable that the length is longer, but if it exceeds 20 mm, the polyacrylonitrile fiber is kneaded in the resin and entangled with the polyacrylonitrile fiber when the resin is extruded, resulting in dispersibility. Is deteriorated and physical properties are deteriorated, which is not preferable. In addition, polyacrylonitrile fiber is 0.1
60% by weight is added. It is preferably 1 to 50% by weight, more preferably 1 to 40% by weight.
