The present invention relates to a vehicle panel with improved peel resistance and impact resistance, which comprises: an outer panel made of a first material; an inner panel made of a second material and coupled to one surface of the outer panel; and a thermosetting resin adhesive layer with elasticity interposed between the outer panel and the inner panel, and bonds the outer panel and the inner panel. The thermosetting resin adhesive layer is coated in a honeycomb structure. According to the present invention as described above, since deformation energy generated by different elongation ratios due to thermal deformation of the outer panel and the inner panel made of different materials is absorbed through a deformation behavior of the interposed thermosetting resin adhesive layer, the peeling among the outer panel, the inner panel, and the thermosetting resin adhesive layer is able to be prevented. In addition, the inner panel is prevented from being easily broken due to an external impact as the shock transmitted from the outer panel is dispersed and transmitted to the inner panel through the thermosetting resin adhesive layer.

    본 발명은 내박리성 및 내충격성이 향상된 차량용 패널에 관한 것으로서, 제 1 소재로 이루어진 외패널 및 상기 외패널의 일면에 결합되고, 제 2 소재로 이루어진 내패널 및 상기 외패널과 상기 내패널 간에 개재되고, 상기 외패널과 상기 내패널 간을 상호 접착하며, 탄성을 가지는 열경화성 수지 접착층을 포함하되, 상기 열경화성 수지 접착층은 허니컴 구조로 도포되는 것을 특징으로 한다. 상기와 같은 본 발명에 의하면, 서로 다른 소재로 이루어진 외패널 및 내패널의 열변형에 따른 상이한 연신율에 의해 발생되는 변형에너지를 개재되는 열경화성 수지 접착층의 변형 거동을 통해 흡수함으로써, 외패널 및 내패널과 열경화성 수지 접착층 간이 박리되는 문제를 방지할 수 있게 된다. 또한, 외패널로부터 전달되는 충격을 열경화성 수지 접착층을 통해 내패널로 분산시켜 절달함에 따라 외부 충격에 의해 내패널이 쉽게 파손되는 것을 방지할 수 있게 된다.
