Layered product, electromagnetic-shielding molded object, and processes for producing these

Applying a sizing agent as a water dispersed sizing agent to a continuous carbon fiber bundle consisting of 20,000 to 150,000 filaments, controlling the packing density in a range of 5,000 to 20,000 D/mm, cutting the carbon fiber bundle in a wet state of 10 to 35 wt % in solution content at the time of cutting, and drying with vibration at a solution content of 15 to 45 wt % before drying.

Process for producing chopped carbon fibers

A bundle of short chopped carbon fibers impregnated with a sizing agent, the short fiber bundle having an average weight per unit length of 1.7 to 4 mg/mm in the fiber length direction and a coefficient of variation of 30 to 60% in the distribution of weight per unit length in the fiber length direction.
