A composite of the present invention is prepared by supplying a thermoplastic resin to a main feeder, supplying a plurality of carbon fiber groups to a side feeder, and extruding the same. The carbon fiber groups are formed of a plurality of carbon fiber monofilaments having a length of 6 to 8 cm and oriented in a single direction. An objective of the present invention is to provide an environmentally friendly composite capable of recycling carbon fiber-reinforced plastic scraps (CFRP scraps) and a method preparing the composite. 본 발명의 복합재는 열가소성 수지를 메인 피더로 공급하고, 복수의 탄소섬유 그룹을 사이드 피더로 공급하여 압출하는 단계를 포함하여 제조되며, 상기 탄소섬유 그룹은 6 내지 8 cm 길이의 탄소섬유 단사가 복수개로 형성되며, 단일 방향으로 배향된 것을 특징으로 한다.
