According to the present invention, disclosed is an impact-absorbing reinforcement structure for center pillars including a high-strength section, a medium-strength section, and a low-strength section, divided from each other and integrally formed. The high-strength section is composed of carbon fiber reinforced plastic (CFRP) formed by impregnating carbon fiber with a resin and is disposed at an upper region of a vehicle center pillar. The low-strength section is composed of a composite material formed by impregnating carbon fiber and olefin-based fiber with a resin, has lower strength than the high-strength section, and is disposed at a lower region of the vehicle center pillar. The medium-strength section is composed of a composite material formed by impregnating carbon fiber and olefin-based fiber with a resin, has strength between the strength of the high-strength section and the low-strength section, and is disposed at a central region of the vehicle center pillar.

    본 발명에 의한 센터필라용 충격 흡수 레인프 구조는, 고강도부, 저강도부, 중강도부 영역으로 구분되는 일체형 센터필라용 충격 흡수 레인프 구조로서, 상기 고강도부는, 탄소섬유에 수지가 함침된 탄소섬유 강화 플라스틱(CFRP) 재질로 형성되어 센터필라의 상부에 배치되고, 상기 저강도부는, 탄소섬유 및 올레핀계섬유에 수지가 함침된 복합 재질로 형성되어 상기 고강도부의 강도보다 낮은 강도를 가지고, 센터필라의 하부에 배치되며, 상기 중강도부는, 탄소섬유 및 올레핀계섬유에 수지가 함침된 복합 재질로 형성되어 상기 고강도부의 강도와 상기 저강도부의 강도 사이의 강도를 가지고, 센터필라의 중앙부에 배치되는 것을 특징으로 한다.
