The present invention relates to an interior/exterior material for a vehicle. According to the present invention, a surface material (24) and a backing material (26) are bonded by hot melts (28, 30) to upper and lower sides of a main body (22) foamed and molded with polyurethane (18, 20) by combining a corrugated cardboard (12) between upper and lower glass mats (14, 16). The corrugated cardboard (12) used for foaming and molding the main body (22) has inlet holes (38, 44) formed between cardboards (34, 40) attached to an upper surface or upper and lower surfaces of a corrugated medium (32) to allow the inlet holes (38, 44) to delay a penetration speed of the polyurethane (18, 20) for the corrugated cardboard (12), thereby minimizing a usage amount of the polyurethane, and allowing a sufficient amount of the polyurethane (18) required for bonding with the corrugated cardboard (12) to remain even in the upper glass mat (14).

    본 발명은 자동차용 내/외장재에 관한 것으로, 상하글라스매트(14)(16) 사이에 골판지(12)를 결합하여 폴리우레탄(18)(20)으로 발포성형한 본체(22)의 상하에 표면재(24)와 이면재(26)를 핫멜트(28)(30)로 접합형성하여 구성하되, 본체(22)의 발포성형 시 이용되는 골판지(12)는 골심지(32) 상면 또는 상하면에 접착되는 판지(34)(40)에 유입공(38)(44)을 형성하여 상기 유입공(38)(44)이 골판지(12)에 대한 폴리우레탄(18)(20)의 침투속도를 지연시켜서 폴리우레탄의 사용량을 최소화하면서 상부글라스매트(14)에도 골판지(12)와의 접합에 필요한 충분한 량의 폴리우레탄(18)을 잔류시켜줄 수 있도록 한 것이다.
