    Abstract: The present invention relates to an apparatus and a method for manufacturing a soft magnetic composite using ultrasonic vibration and a soft magnetic composite manufactured using the ultrasonic vibration. More specifically, the present invention relates to the apparatus for manufacturing a soft magnetic composite using ultrasonic vibration including: a die that has a putting-in space as an open space in which a powder material is put; a punch set that is inserted into the putting-in space and presses the powder material; an ultrasonic vibration applying unit including ultrasonic vibrators which are arranged along a circumference of an outer die surface of the die and are provided to come into contact with the die; a main body that is positioned below the die and is formed to slide around the die toward an outer circumference; and a control unit that controls a frequency of the ultrasonic vibrators depending on a degree of pressure of the punch set, a method for manufacturing a soft magnetic composite using ultrasonic vibration, and a soft magnetic composite manufactured using the same.

    Abstract: The present invention relates to a poly(ethylene-aliphatic diene)-g-polystyrene-based copolymer having an improved mechanical property and heat resistance, and a method for preparing the same. More particularly, the present invention relates to a poly(ethylene-aliphatic diene)-g-polystyrene-based copolymer, which includes an ethylene-aliphatic diene copolymer as a soft segment and a polystyrene-based polymer grafted to the soft segment as a hard segment, and a method for preparing the same.The poly(ethylene-aliphatic diene)-g-polystyrene-based copolymer has elasticity equivalent to that of SBS or SEBS, and improved mechanical properties such as tensile strength and heat resistance, thereby being used as a substituent for SBS or SEBS.

    Abstract: The present invention relates to a composite material for a transport, including a polypropylene resin and a carbon long fiber, and more particularly, to a fiber reinforced composite material composition for a transport including 40-90 wt % of a polypropylene resin, 5-60 wt % of a carbon long fiber having a fiber diameter of 1-50 μm and a weight average fiber length of 20-150 mm, and 0.3-10 wt % of a compatibilizer. The compatibilizer includes one selected from the group consisting of an ionomer, a copolymer of propylene-polar monomer, a modification water added polymer and combinations thereof. The composite material has improved interface properties between the polypropylene resin and the carbon long fiber owing to a specific compatibilizer, improved rigidity, impact resistance and heat resistance, and may be applied to various fields requiring the fiber reinforced composite material as well as various transports including an automobile.
