Composite material for means of transport including polypropylene resin and long carbon fiber

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.
