Abstract: Disclosed is a method of and an apparatus for manufacturing a sheet molding compound (SMC), the method including: continuously supplying a bottom film; applying a bottom resin on the bottom film; continuously supplying a carbon fiber; spreading the carbon fiber for widening; cutting the carbon fiber into a predetermined length and distributing the cut carbon fiber on the bottom resin; continuously supplying a top film; applying a top resin on a lower surface of the top film; and laminating the bottom film and the top film such that the carbon fiber is impregnated with the resin. According to the present invention, a large tow carbon fiber is widened by spreading to improve resin impregnability, thereby being capable of manufacturing a high quality SMC having improved physical properties with low cost.

Abstract: Disclosed is a pressure vessel for storing high pressure gas, the pressure vessel including: a liner (10) provided to be a tube body of a predetermined diameter and having male thread parts (102) provided on opposite end parts thereof; inserts (20) having combining parts (201) provided on outer surfaces thereof and through holes (202) provided on middle parts thereof; a first sealing member (30) provided between the end of the liner (10) and the inner surface of the insert (20); a fastening member (40) having a female thread part (401) screwed to each of the male thread parts (102) and having a combination hole (402) into which each of the combining parts (201) is inserted; and a reinforcing wire (50) wound so as to cover an entirety of an outer circumferential surface of the liner (10).

Abstract: Disclosed is a pressure vessel for storing gas. The pressure vessel for storing gas includes a body provided with a hollow portion and configured in a cylindrical shape having a constant thickness along an axial direction thereof; a pair of caps provided with respective injection holes formed through the caps along the axial direction, having threads on an outer circumferential surface thereof, and engaging to both ends of the body to close the body tightly; a flange coupled to each end of the body, the flange having a central opening; and a metal wire wound on an outer surface of the body to strengthen the body. In addition, one end of the wire is fixed on the outer surface of the body by soldering and an opposite end of the wire is fixed on the wire wound on the body by soldering.
