Disclosed is an impact beam structure of an automotive CFRP door. An embodiment of the present invention can simply and easily mount an impact beam on an automotive CFRP door manufactured using a CFRP material and optimize a sectional structure of the impact beam to effectively cope with side collision. Besides, the present invention provides the impact beam structure of an automotive CFRP door which can prevent deterioration of appearance of the CFRP door due to mounting of the impact beam by suitable matching with an inner panel of the CFRP door. The impact beam divided into an outer impact beam and an inner impact beam and coupled to each other is coupled to an inner panel of the automotive CFRP door to reduce the number and weight of components and increase rigidity. 차량용 CFRP 도어의 임팩트 빔 구조가 개시된다. 외측 임팩트 빔과 내측 임팩트 빔으로 분할 성형되어 서로 결합된 임팩트 빔이 차량용 CFRP 도어의 인너 패널에 결합되어, 부품수와 중량을 저감 및 강성 증대를 도모한다.
