Zusammenfassung:	The present invention relates to a bumper beam structure for a vehicle and a manufacturing method of the same. According to an embodiment of the present invention, the bumper beam structure for the vehicle comprises: a first beam body made from thermoplastic fiber composite materials to have a first crash box unit; and a second beam body engaged with the first beam body and made from thermoplastic fiber composite materials to have a second crash box unit. The crash box unit consists of a first and second crash box. According to the present invention, the first beam body and the second beam body of the bumper beam structure for the vehicle are formed by using two or more kinds of thermoplastic fiber composite materials, and the crash box unit is formed by engaging the first beam body with the second beam body, thereby maintaining high strength and hardness by the complementary action of the two or more kinds of thermoplastic fiber composite materials. 본 발명의 일실시예에 따른 차량용 범퍼 빔 구조체는 열가소성 섬유복합소재로 이루지고, 제1 크래시박스부가 형성된 제1 빔바디와, 상기 제1 빔바디에 결합되고, 열가소성 섬유복합소재로 이루어지고 제2 크래시박스부가 형성된 제2 빔바디를 포함하고, 상기 제1 크래시박스부와 상기 제2 크래시박스부가 결합되어 크래시박스부가 형성된다. 본 발명에 의하면 2종 이상의 열가소성 섬유복합소재를 이용하여 차량용 범퍼 빔 구조체의 제1 빔바디와, 제2 빔바디를 형성시키고, 제1 빔바디와 제2 빔바디의 결합에 의해 크래시박스부를 형성시킴에 따라, 2종 이상의 열가소성 섬유복합소재의 상보적 작용으로 높은 강도와 경도를 유지할 수 있는 차량용 범퍼 빔 구조체를 얻을 수 있다.
