A dry granulation process using a twin-screw extruder for granulating a powder mixture which includes at least one active ingredient and at least one carrier. The process includes steps of kneading the powder mixture in the screw barrel of the twin-screw extruder at a barrel temperature below a melting point of the at least one active ingredient and a melting point or a glass transition temperature of the at least one carrier to provide a kneaded powder mixture, and extruding the kneaded powder mixture to form granules. Granules and tablets produced using the dry granulation process in the twin-screw extruder are also provided.

A carbon fiber-reinforced thermoplastic resin composition includes a thermoplastic resin (A), a carbon fiber (B), and a titanium compound (C), an amount of the thermoplastic resin (A) being 10 to 65% by weight, an amount of the carbon fiber (B) being 35 to 90% by weight, based on 100% by weight of the total amount of the thermoplastic resin (A) and the carbon fiber (B), and an amount of the titanium compound (C) being 0.01 to 5 parts by weight, based on 100 parts by weight of the total amount of the thermoplastic resin (A) and the carbon fiber (B).
